I know there are a lot of Bilstein fans here, so I'll try to not step on any toes...

 

My truck is a 2007 Silverado Classic 1500 Crew Cab.  I bought the truck used in 2010, and it's been a great truck.  About 4 years ago, I decided to replace the factory original shocks on the truck.  After doing a lot of reading, including posts on this site, I bought a set of Bilstein 4600 series shocks for the truck.  I haven't been happy with the ride comfort ever since that day.  The truck has felt like it has no suspension whatsoever in the rear.  The issue was especially noticeable on going over all the joints on a concrete interstate highway.  I experimented around with different air pressures in the rear tires, and I even tried running a small amount of air in my air bags, which I normally keep empty when not pulling  a trailer.  Nothing made the ride acceptable to me.

 

Finally, a couple of weeks ago, I put the original shocks back on the rear.  It rode much better than it did on the Bilsteins.

 

I wanted the Bilsteins to work.  I raced dirt cars for 28 years, and the best shocks I ever had on any of my cars were Bilstein's S9Z series shocks.  I also ran shocks from Afco and Pro over the years, and the Bilsteins were superior to those.

 

I have no doubt that if I was driving my truck off-road, the Bilsteins would probably be the absolute best shocks I could buy.  However, I don't drive my truck that way.  It runs around town and up and down the highway, and I occasionally use it to pull my 20 foot car hauler.  I'm getting old, and a nice smooth ride is important to me.  The Bilsteins just didn't give me what I wanted.  I guess I'll also add that I've got a set of 4600 series Bilsteins on my '96 model crew cab dually, and I am happy with them there.  I know that truck is never going to give a smooth ride no matter what shocks I put on it.

 

I'm going to buy another set of shocks for my truck.  I've been doing a lot of reading again, and I know that I won't buy any more monotube shocks.  I'll definitely put twin tube shocks on it.  I've looked at "stock replacement" shocks that advertise OEM ride quality from all the customary brands like Monroe, KYB, and some others that I've never even heard of.  Right now, I am leaning toward the AC Delco "Professional" line of shocks, which I assume are probably made by Tenneco, and probably virtually identical to Monroes.

 

I guess I really don't have a question here, but if anybody wants to offer any comments, I'd love to read them.

I am sorry your bilstein experience wasnt up to par.  I went with the 5100's on my Z71 and was kicking myself for not doing it sooner.  That being said, you have to find what is good for you.  For me I found my truck improved in keeping my tires to the road in almost any condition, which made for better cornering, stopping and take offs.  I also noticed that I didnt have as many hydroplaning issues in wet weather.  Can I ask if you set the shocks before you installed them? It just seems very odd that it felt like you had no suspension at all, and that is most always the case with worn shocks.

It felt like the opposite of worn shocks.  It felt like the shocks weren't allowing the springs to do their jobs.  It felt like the shocks were a couple of swedge tubes that had the chassis locked into position.  The tires would just bounce along the highway because there was no give in the suspension.

yeah that is odd for sure.

Update:

 

After driving the truck for a couple of weeks, I was still unsatisfied with the ride quality.  I started playing around with air pressure in the rear tires and weight in the back of the truck...

 

I now have the Bilsteins back on the rear of the truck.  I am carrying 180 pounds of dead weight in the back of the truck, and I have the rear tires a couple of pounds below the pressure prescribed on the door jamb.  I am now satisfied with the ride quality.

 

The Bilsteins are good shocks.

Yep, tire pressure and extra weight, that what I would try. Sounds like it worked for you. Sometimes its hard to get the tires and shocks to work together as a suspension system, but once you get it dialed in - your good to go. I think a lot of people underestimate how important the tires are in the suspension. They find out quickly when they get those big 24" wheels, with super thin rubber band tires wrapped around them. 8 ply heavy duty tires make for a rough ride too. You probably already know all of this, but some readers don't.

A number of years ago, Nascar teams started measuring the spring rates of tires, and used that in their weekly setup prep for races.  It was another way to gain an advantage, and of course, it drove up expenses....

 

Nascar banned the practice.

I can see how measuring the performance of the tires would be useful, but how would Nascar ban the practice?

 

Speaking of Nascar, I bought a used oil cooler at auction. It came from the Richard Petty Nascar race team. I installed it on my ATV. It did not make my ATV as fast as a Nascar though...

A truck with a 2K pound payload capacity is sprung and shocks valved for 2K pounds of payload. Without the load it is both over sprung and over dampened and usually highly digressive. Add some E rated tires or aggressive A/T's on big rims????? Rides like an empty dump truck. 

 

It's a method OEM's use because it uses the fewest cheap parts and 'right' for the maximum load when carried to keep backsides out of jail. 

 

I bought new springs (leaves) from Deaver that were 15% lighter, have 11 leaves and hung them in Sulastic hangers and control them with King Piggy Backs gas shocks. Something similar up front. Does it ride like a Caddy? Nope but my dental work stays put, my arthritic back is happy and the tires stay on the ground in the wash board sections. Could not be happier. That said...could have done it cheaper looking in the rearview mirror. Could have used the lightest 2007 factory spring or even run mono leaf removing the second and overload from the set it came with, Sulastic and FOX remote N2. Both of the shocks mentioned are LINEAR valving. HUGE difference in 'hit'. 

 

What about loosing the load capacity? Two words. AIR BAGS.

Since the tires are issued to the teams when they arrive at the track each week, the teams were measuring the spring rates of the tires at the track.  That made it easy for Nascar to police it.

 

Nascar bans practices and changes rules all the time to cut expenses for the teams, to protect teams from themselves.  A perfect example was the with the impact guns used to change tires on pit stops.  Some of the teams were spending a fortune on R&D to develop faster guns that could shave fractions of seconds from their pit stops.  Nascar stepped in a couple of years ago with spec pit guns, and started issuing them to the teams each week.  Then some teams started using helium to drive the guns faster than they were designed to operate, and the guns started failing.  Nascar stepped in again and ordered the teams to use only nitrogen to drive the spec guns.

I raced in under some sanctions whose rules were pretty much, "If we didn't tell you that you could...you can't". They even went so far as to say that only the inspectors inspection tools were valid and only by the methods and skills that particular inspector was capable of. HIS gauge only, calibrated to HIS traceable standard. Of course there was variance from track to track so you had to learn how far OFF the edge you could build and be competitive. Guess who won all disagreements?

 

What a way to run a Rodeo. Oh, I knew what they were doing. Trying to avoid the NASCAR Dutch boy fairy tail  type rule modification. It was off the rails before the ink was dry. :nonod:

 

Best outfit I raced under was NHRA. But even that pig doesn't fly straight. Big money teams do not like little guys winning and will protest you into bankruptcy.

I raced dirt cars for 28 years.  Most local dirt tracks did their own thing, and rules enforcement was always spotty.

 

I did race a number of years under a sanctioning body (IMCA) that used the rulebook as a way to make money.  If a parts manufacturer did a sponsorship deal with them, they would spec parts from that manufacturer.  The parts suppliers and the sanctioning body were all making money on the backs of the racers.

 

ETA:  IMCA has spec'd things like heads, intakes, carburetors, a-frames, transmissions, rear ends, and even crate engines.

Oh yea. Know that rule. LOL. How about when the parts manufacture has that deal, has it's own "factory backed" team and the team gets first pick of stock! Don't they call that hunting in a baited field? :rollin:

 

We use to do things like order 32 rods. Hand select the best 8 after inspection and pay the restocking fees. Which makes things fair and above board and your still doing your part to find the best. Except if the stock has been picked over by the factory teams before delivered to stock. 😡 They would go over a thousand rods and keep the top 10%. (Stock and Super Stock classes were worst of the bunch). And they all did it.

 

A factory backed team could buy a "Body in White" at 20% of floor cost. Private teams paid up full and had to strip a car to 'White'. IF you had a friend with a backing MAYBE you could buy the car on the floor at cost with a wink and a nod.

      New to Me 2010 SLE (Quirks, Issues)

      By davester · Posted

      not all plugs will be used.  gm uses more generic harnesses that support most/all options, and if your truck doesn't have a specfiic option, the plug won't be used (commonly will have a dummy insert in the plug , or it'll be taped up, but some may just be left as is).  But it's sldo possible some p.o. has installed the wrong/cheaper parts that aren't correct for your vehicle...

      New to Me 2010 SLE (Quirks, Issues)

      By fm2176 · Posted

      First off, I'm not trying to just get easy advice/fixes for the issues I've noticed so far.  I'll be combing through the site via searches and such, and if past experiences are any indication, should find what I need.  For the sake of conversation, though, I figured I'd post the handful of things I've noticed in the 12 hours since buying my 2010 SLE CCSB.     Indicator lights: Airbag and TPMS.  The tire pressures aren't reading for any of the wheels, so I'm pretty certain the sensors were either removed, are damaged, or are otherwise inoperable.  I used to mount and balance tires 25 years ago but am pretty much ignorant when it comes to TPMS.  My 2006 didn't have the sensors and this might be the fourth vehicle I've owned that does.     Radio: Rear speakers aren't working.  I removed the driver's side rear door panel and checked the speaker and wiring.  I also removed the sill and b-pillar covers to check the wiring.  A few minutes of Google Fu showed that this is potentially a head unit issue.    Switches: Power mirrors don't turn left/right.  I ordered replacement driver's door switches that should arrive tomorrow.  The windows and locks work but it was only about $20 for all of them.  The driver's side rear window switch lets the window down but won't put it back up.  I think the passenger rear doesn't work at all.  In the coming days/weeks, I'll break out my multimeter to check all of that.   Unknown wiring harness: There's a box attached to the front driver's side of the engine compartment, right where the second battery shelf is located.  There are three plugs, one of which looks like it fits a standard headlight-style bulb (9007 or similar).  It doesn't look like it's plugged into anything.  I'll do some digging and if I don't see anything elsewhere on the site, post some pictures here.   Unknown plugs on brake booster: There are at least two female plugs on the brake booster that aren't being used.  I think it might be a replacement/aftermarket, so maybe those are used for a different application, as there don't seem to be any unplugged harnesses and no indicator lights are on.   Little squeaks when turning: Sounds almost like a bushing around the bed of the truck.  I'll have to pay close attention as I get more familiar with the truck.   Clunk on acceleration: possibly the infamous drivetrain clunk.  My 2006 had it and I'm just not familiar enough with this truck yet to fully grasp what it is.   Anyway, my apologies for the vague and all over the place post.  This truck is new to me, and it's been four years since I drove my 2006.  With 200k miles, I know I'll need to learn this truck quickly to avoid having any major issues, despite being confident it's got much more life to it.  My 2006 had nearly 320k on it when I parked it (nearly 300k of which I put on the truck), and it was still drivable then, though I suspected the head gasket might have blown.  I'd hoped to have that truck back by now, but it's gone forever, as I detailed in my reintroduction thread.

      I always drive in Sport mode. With more driving, I am finding the initial response when accelerating is much quicker now🖕 Lou

      Is it an optical illusion in the pic or is the truck really squatting that much horribly?

      It's Been a Long Time...

      My initial introduction was here.  It's hard to believe that I last posted in February 2013, having just deployed to Kyrgyzstan.  Since then, I've retired from the military and the 2006 Sierra SLT Z71 that first brought me to these pages was lost.  I went forward to Afghanistan in March 2013 and did a lot of sitting behind a computer on brigade staff.  Within 18 months of getting back to the States, I was selected for Drill Sergeant duty, after which I moved back to Virginia (my home state and where I served from 2004-2008).  That '06 Sierra did a lot of driving between Louisiana, Georgia, and Virginia, and ended up with nearly 320k miles by 2022.  By then, the registration had been expired for a couple of years, but the pandemic had all but eliminated tickets for such transgressions.  Admittedly too, I usually drove my wife's SUV or son's car the 2-3 times a week I had to report to work.  Teleworking sure was fun while it lasted.   I started my retirement leave four years ago and stored the Sierra at my sister's house.  A big mess was made when her fiancé passed while she was taking care of business out-of-state in late-2024, and his son pretty much mismanaged everything to do with the estate.  Even so, I was assured that my truck was safe... until it wasn't.  I found out that my truck had been scrapped about four months after the son took over everything.  There's nothing I could do; I'm 1000 miles away and it was technically abandoned property since he'd even trespassed my sister from her own house (she had no claim to it as she wasn't married, and the fiancé was the sole owner).     Anyway, today I got my second Sierra.  This is a 2010 SLE 2WB CCSB with a little over 200k miles on it.  It's got the 5.3L I'm familiar with and should handle what I need it for.  Hauling stuff that won't fit in the Transit Connect (yep, I sold out, but that's the wife's vehicle) and towing a few times a year tops.  The price seemed decent, considering how much people sell their trucks for in the Deep South: $4500.  I've seen similar trucks listed for more than double that.  I got it from a coworker who left his tag on until we transfer the title next week (Louisiana requires a notary for transfers), so I've been driving it all day.  The rear speakers don't work, which is one of the things that brought me back to these forums earlier.  I can't say how active I'll be as a poster, but I'll be scouring the archives while I find out every little thing I can about the 2010s and particular nuances/problems with my truck.   It's definitely not a GMC, but I got another Willys Jeep a few months back as well, so I'm almost at the same place I was when I first joined gm-trucks.com.  My old 1960 DJ3A was sold back around 2010 or 2011; my current Jeep is a 1946 CJ2A.  So, I've got a slightly newer GMC and a much older Jeep.  I kind of wish I still had that F-250 I had way back when too.  The Dakota is long gone and was technically my brother's truck, though I had it registered and insured.  The F-250 had to go when my grandmother's house was foreclosed on due to mismanagement around 2012 or so.     Hopefully anyone that made it this far isn't too annoyed.  I tend to be long-winded, but I'll be doing more reading than posting in the coming months.
