I'm learning a lot here.  I have noticed know one has mentioned shocks and towing, is that a different conversation?

It should be in here also since the shocks control the motion of the truck, loaded or unloaded.  The Bilsteins tow far far better than the stock NHT shocks did.  The NHT were too bouncy and couldn't handle a load as well.

I bought my 18 Z71 (5.3L, 3.42 rear end) for the purpose of towing a 21ft TT.  Loaded trailer about 5200lbs and hitch weight of about 600lbs plus 200lbs to 300lbs of junk in the bed of the truck.

The truck has just over 800 miles and I have made a few close to home trips with the trailer. What I have noticed is how much the rear end bounces when going over bumps i.e. road to bridge joints/transitions. Somewhat unnerving at times.  I'm just wondering if another brand of shocks might reduce some of that bouncing motion.  I have thought about bags, but shocks might be the place to start.

I'm 70 and retired so this is not a daily drive and no mods.  The Ranchos are "OK", but they do seem to let you know every bump and as mentioned in another post, make you feel like a bobble head.

The Bilsteins took all of the bounce away.  It absorbs the bumps without issue.  I tow a 7000lb car/trailer combo and I dont even know it is back there now.  Very stable.

 

Airbags will not help with the bouncing, but will help with squat and leveling the load.  I also have a set of Firestone Ride Rite air bags on my truck to keep it level when loaded up.

Correct the Bilstein 4600's and 5100's are basically an "all around" shock that's built for better control in standard driving conditions, better off road performance for general off roading and 4 wheel driving, and better towing performance.  It really doesn't excel in a specific area of use more than the other.  It's an upgrade to your stock Tenneco's/Rancho's so essentially how you would use your stock truck is how you should still use it with these Bilsteins, but with an upgraded performance in these all-around areas of use.  These shocks aren't built for say taking your truck off of jumps 20' into the air.  The 5100's are good for up to a 1" rear lift and they will level your front end.  Anything more than that and you should consider other equipment.  But these are the best shocks you can buy in my opinion for a stock truck or a leveled truck that won't be abused too terribly much outside of what we'll call "normal" truck usage.

Coming from my 09 Silverado, which really didnt tow all that well, I had just put a set of 4600 on the rear. It did improve. Then I traded it in on my 15, which tows soooo much better. Doesnt bounce around nearly as much as the 09 did. Im almost scared to swap out anything suspension wise lol.

I came from a 2000 3/4 ton that was all stock.  Being a 3/4 ton it really wasn't bouncy, but I didnt care for the 4 speed and the lack of power at highway speed.  This '18 NHT blows the old 3/4 ton out of the water, and it only got better with the Bilsteins.  If you're happy with the truck now no need to change anything, but if the rear bounce starts to bother you upgrading to the 4600 or 5100 will make it better.

I found the best deal on them at 4wheelParts. $345 free shipping.

That was with a coupon code at the time.

That's not bad at all,I just cant see taking off the Ranchos and spending 350 dollars when I only have 37,000 miles on my truck. I do agree they are ruff riding. The bilstiens will definitely be a good investment down the road though.

If they are rough riding now, they are shot.

Mine were shot at 40k

You do not have to buy all 4 at once.

The rears are about $75 a piece.

$106 each for the front.

The 5100's are nice but there are other brands very similar in design, function and cost.

Pro Comp and Eibach just to name a couple.

If I was using my truck as a daily drive or to run errands the Rancho's would be fine for now, but as I plan to use it mostly to tow, I decided to order a set of Bilstein 4600's for the rear and deal with the other end after the first of the year. 

The wife can't quite figure out why I have to get new shocks for a brand new pick-up.  And while I agree with her, I did do my best to explain why. 

I haven't told her about the fronts.   :sigh:

Chris,

 

The stock ranchos are bricks. Thanks for chiming in and please vote!

I have heard positive reviews on the 9000xl's  How do you like them?

    • How many miles were on the truck when you bought it and was there some form of oil change history generated through a dealer or an independent shop although not much would show up if the owner had changed their own oil. Just curious if it was a maintenance issue or if there was something off from the start, surely one would think the original owner would have realized it was using a lot of oil, its hard to go back in time and find out the true story of mysteries like this. Well hopefully the warranty company will go for it and just install a new engine, that would be the ideal outcome.    I still have so few miles on my truck as per not quite 9000 and will be changing the oil shortly which has around 2700 miles on it or so and its down so little on the dipstick from where it was at the beginning of this oil change that I could make the "claim" that it uses no oil but in reality would be a very small amount, less than a 1/16 of an inch. Just driving empty/not towing and easy driving so hard to say what it would do if it had a load behind it for oil consumption. So far very impressed with the very minimal oil usage. 
    • I have a 2015 Silverado and sometimes I can not get in to the truck. I use the key to unlock the driver door. Something is locking the truck when I unlock it, last night I left the truck open and this morning it was locked with the mirrors folded in. This happens while driving so it is now a safety issue. I reach down for the folding button and they open, then they close again.  Any advice, thank you,   Ed
    • Did you ever find a resolution to this? my 2019 Silverado 1500 is showing the exact same headlights issues with the exact same symptoms.  would help a ton if anyone has any advice on this or better yet a known solution..
    • Wawa and Meijer here have ethanol free (88 & 89) I use for my mower and lawn equipment.  Its not much more than reg.  I paid $3.29 a few weeks ago.  
    • tl; dr I've now reached the 6th floor of hell. I'm chronicling my journey for my morning readers.   Pulling the top of the intake apart was moderately easy but it involved a lot of parts, connections, and minutae. I was preparing for the new fuel lines to arrive ("nut and bolt kit" it's called). The fuel line connections are notched and held in place by the manifold and a metal plate with a T27 screw.   It's on the back of the intake, under the firewall, with little clearance, and two hard metal fuel lines in the way. I was using Franken-tools (weird combinations of 1/4 inch ratchet with/without an extension, with a bit holder for my T27) to get in there. One of my sockets and bits fell off and has yet to emerge on the floor. I lost a second setup and that's when I almost started throwing tools. But that was the point at which I had gotten traction on the Torx head, and it promptly stripped. No more traction.   I started humming "1-877-kars-4-kids" because I was about at that point. You know what? I'm $1500 into this thing and I can make it disappear just as quickly. This isn't fun anymore. I had spent a lot of time already "tidying" around the engine bay: Fixing all the "someone's been here before!" BS. The truck has been exclusively dealer- and shop- serviced and I'm reminded of why I never let other people work on my cars unless absolutely necessary.   Speaking of dealer service. This truck has a 1" stack of records going back to 1995. I put them all in an excel spreadsheet, date/mileage/description.   The CPI spider has been replaced 4 times in 85k miles. The EGR? Another 4. Multiple, multiple O2 sensors. One Cat. 4? Sets of plugs and wires, and I swear half the stack is diagnosis paperwork for "misfire, runs rough, extended crank, dies at stoplights".   GM was producing some proper crap back then. And it was still well within the era of brittle/crappy plastic. (Windows 95 was released the same month this truck was sold new, we HAD the technology!!)   There (was) a plastic shroud around the evaporator core and HVAC fan in the engine bay. I noticed a chunk of it missing so I poked at it some more and it literally shattered. Touched it some more and pieces were crumbling off. Had a good laugh. Clearly whatever plastic garbage they were using had broken down over 30 years and was literally turning to dust. That was a good half hour of using a shop vac to remove the rest of it.   Back to it.   I was going to give up for the evening but then decided I'm already level 10 pissed off at the stripped screw: G* D* it, give me my tools back -- and my JOY. We'll do this the hard way: The whole intake is coming off.   Blazer won Round II. After finally finding and accessing the 12 intake bolts and using a pry bar to unseat it from the heads, it popped loose in an explosion of gunk and grime raining down into open ports. Awesome.   6 times I reminded myself: Be careful of the temperature sender on the front of the intake.   YEAH, I forgot again and snapped it clean off in the removal. Add another $20 to the ever-growing list of new parts this thing is consuming.   The shame is, long before removing the intake, I had changed the oil in prep for Tuesday's momentous fuel line replacement that was going to be the magic fix and I'd have a running Blazer to tool around in this next weekend. The intake removal, including raining gunk, also gushed dirty coolant all over the valley. Of course it did. Welp, there goes another $35.   I now need an intake gasket set, bolt set, coolant temp sensor, another 5 quarts of oil, some RTV. Don't worry, I've already got 3 new jugs of Dexcool and a thermostat waiting. I'll fill it with clean water first to get it running, dump it, and then add the Dex later on in case... well, let's not go there. I'm only tearing this down once, next time the truck is going on Marketplace for FREE.   Oh, and I'm going to need vacuum hose for all the stupid connections placed at the rear of the engine which have since disintegrated. Come on, GM....tell me you don't do that anymore?   Oh, and the ears on the distributor where the cap screws down are both cracked. I mean, why not put a new distributor in it too. You get a distributor, YOU get a distributor, Everyone gets a new distributor!   This truck isn't out of the woods yet...I'm already questioning how much more time I'm willing to sink in.
