Yellow/Blue = 4600

Silver/Black = 5100

 

Both a big upgrade over the stock shocks. Go with the 4600 if you want to keep stock height or are needing maximum control for towing or want to run a leveling spacer. Go with the 5100 if you want to level the truck without a spacer or if you like to go offroad.

Running stock 16 1500 crew z71. I have a Leer cap on back which probably adds 300 lbs and already squats the back a bit over stock. Would there be a noticeable benefit to just do the rears with 4600 or 5100 simply because I can do it myself? I don't go off road that much and would like a smooth ride on the highway.

 

Do the 5100s that are adjustable, do they actually raise the front all by themselves? Or is it just to account for a seperate lift or spacer? If I wanted to raise the front say an inch to level it out a bit would you need to replace other suspension parts and get an alignment, or is all you need the are the 5100s?

Thanks

5100 front shocks have a circlip that raises a perch that the coil spring rests on. Raising the circlip raises the front of the vehicle. I have mine set at the third setting which leaves me about 1" of rake. I also have a topper (ARE) on mine.

 

You will need an alignment if you raise the vehicle.

Thanks for the info. How was the ride quality after the 5100s with the cap on the back? I noticed adding the cap alone really tamed the rear bounce from how it drove with an empty bed.

You should only see improvements in the way it handles and carries the weight of the cap. We recommend you go with the 5100s. The front shocks have an adjustable spring seat to level out the front. All you need is the shock set, they come with everything required to install and level the vehicle, no additional parts needed :)

Well to be honest I'm not too thrilled with the rear ride. It's a little jarring. I had a Tacoma with Bilstein 5160 rear reservoir shocks that rode much nicer. I may put the stockers back on.

Could I clear a 285/50/22 Nitto G2 with Bilstein 5100? That is a 33.2" tire at 11.2" width. Or even without any mod? The stock 285/45/22 is 32.1" and also 11.2" width.

 

275/60/20 fit without any modifications--that's a 33" at 10.8" width.

It will depend on the offset & backspace of your wheel, that tire is wide and may rub the upper control arm. Height wise it should be no problem to fit with the BIlstein opn the top setting.

So, according to the pdf, are we really only looking at 1.8 of front lift on the Sierra/Silverado with the 6112's?

 

Anyone know if these numbers are confirmed?

 

Thanks.

Not confirmed yet - check out this thread for the most recent 6112 info: http://www.gm-trucks.com/forums/topic/190363-bilstein-6112-coilovers-5160-rear-shock-interest-thread-50-sets-co/?hl=6112

I have been thinking of putting lowering shackles on mine to try and even the rake. Would either of these shocks be good for this. I would like to take some of the bite out of the Z60 harshness. Sprinkle GSM in front would really probably help. I am 2wd and extended cab.

 

What the heck does Sprinkle GSM in front would really probably help. My phone must have auto corrected that. I was thinking springs in front would probably really help.

 

Would my truck benefit more from 4600 or 5100's? I am wanting some of the Z60 harshness taken away. Expansion joints on the interstate and bridges currently suck.

LOL! If you are lowering the truck, go with the 4600 as they are shorter than the 5100s.

 

Thanks man for the reply. At this time I only want to lower the rear with shackles. No plans for the front.

I have a 2017 CCSB 4X4 with the 6.2L (L86) and Max Trailering Pkg. I tow a 34' Airstream trailer (9,100 pounds and 1,100 tongue weight. I want to maintain the factory ride height, but I'd like a more controlled ride, especially towing. I want the damping to be more controlled...not harsh.

 

Would the 4600 series Bilsteins be an improvement over the factory shocks?

 

Thanks,

 

Steve

Are their any Bilstein's for lifted trucks? I have a 7" lift on mine but I'm not too impressed with the shocks that came with it.

    • I was using recirc/max air. Especially if it really hot i start out by lowering the front windows a little with regular ac the go to recirculation after a few and rolling windows up. And it does not have the newest refrigerant. It has per the info under the hood r134. Not the new r1234yf.  
    • tldr; Shade tree mechanic stumped by variable displacement AC compressor.   Not Silverado related, but for my 2000 Camaro SS. I've never really used the AC since acquiring the car a good handful of years ago. I plan to take it on a trip this summer so I wanted to make sure the AC was in good shape. On an 73 degree day in the shop with the car idling I set the AC on "Max", temp set to cold, and fan on hi. The compressor turned on and air turned nice and cold.   I let it run for several minutes but noticed the compressor never cycled off. The engine was up to temperature enough that it began cycling the cooling fans on high. I had a set of manifold gauges hooked up and it was consistently at about 25 psi on the low side and between 200 and 225 psi (warm engine) on the high side. Per temperature charts, the low side is low (should be 30-35) and the high side is a little high (up to 170 per chart). I read the low pressure as potentially being under-charged underscored by a continually running compressor This was also underscored by temp readings of mid-20 degrees at the vents. Not just cold, freezing cold. Switching off the AC but leaving the HVAC fan on high produced a deluge of condensation underneath the vehicle. I was getting ice buildup on the evap core most likely.   The low reading (25psi) concerned me that the compressor wasn't switching off so I swapped out the pressure switch. No change in behavior, still ran constantly.   The AC clutch works fine as it engages/disengages with the HVAC switch on command. The compressor relay is good as I swapped it with two different known good relays just to be sure. Having eliminated that, and the pressure switch, I added refrigerant, thinking the constant run and low "low" pressure were signs of a slight undercharge. Makes sense, the car is 26 years old and it doesn't appear the AC system has ever been touched.   Adding some R134a didn't meaningfully change the low side pressure. And that's when a lightbulb flashed upstairs. While I consider the car "old", it's possibly "new" enough to have a variable displacement compressor. Did some reading and sure enough. Dangit. I don't work on these for this reason.   Adding refrigerant means the compressor will just compensate and won't really change pressures until it's severely overcharged or undercharged. But at least I wasn't getting ice/frost anymore, but instead high 30 degree temps out of the vents. That's more normal, but with variable displacement now I have no idea where my charge level is at. It's probably overcharged now. The high side even with the engine radiating serious heat was never really over about 225.   The static pressure at room temperature is dead on, before and after the charge. Both high/low equalize after some rest.   I'm thinking I'll need to take it to a shop. I want the proper charge level so I'm not working the compressor too hard. The only way to get an accurate charge is to evacuate and then re-charge with the exact amount specified for the system -- at least that's what I'm reading.   Anyone here with modern automotive AC knowledge?  
    • Mine is in the shop for the AC now. While it did get cold after a bit, it would take a while to even start to cool the air at all. Turns out the compressor was bad and cycling. 
    • I call B.S. when I first moved to Texas my first house would only cool to 80 with the Texas heat. The AC tech said it was normal at 100 degrees outside. I remodeled the house put in a new AC. I could hang meat. My cars may need recirculating to start. Once moving it switches to regular AC and I could hang meat. Living in Texas no one would put up with only 20 degrees difference. 
    • AC in home or auto only cool down 15-25 degrees from outside temp, but what will help is to put the ac in recirc mode this will recirc the Inside cabin air rather then trying to cool down the outside hot air, I always have mine in recirc mode.
