‘21 RST 6.2 Standard Bed sits low

[Swellchevelle]

I’m looking to slightly raise this truck at all 4 corners. It seems to sit lower than other similar trucks. Id my combo built to ride lower? RST  with the 6.2L engine and 6’6’ bed. Towing hitch seems really low and it squats with an unloaded 16’ equipment trailer. Should I look at helper springs, also interested in the active rear suspension helper (longitudinal coil spring). My only upgrade was swap of stock 18” rims/ tires for 2024 ZR2 20” rims with stock tires.

2024 Colorado ZR2 comes with 17s.  Silverado and Silverado HD come with 18s.  I don't think you have what you think you have.

 

If you want to lift your truck at all 4 corners, get a proper lift kit.

 

If you want to help eliminate your rear sag when towing I recommend Sumo Springs, weight distribution, or airbags.

I feel like my 21 6.2 RST has sagged over time.  I initially installed a 1.5 front lift, and after install thought I should have went with 2” because back still seemed too high, so I bought a .5 bottom of strut spacer.   Never installed it, because soon enough the rear started sagging, so much so that I installed a 1” rear spacer to level it back out. Now it looks like the front is starting to sag, so I may install the .5” front spacer after all.

The wheel swap I did was from a 2024 Silverado ZR2 to be clear not a Colorado. Saw the truck it came off basically a Trail Boss with a 6.2L

Do you believe the springs are just not adequate? I haven’t had this issue with any other truck.

Trucks are designed to squat with a load on the back.  Its normal.  

 

If it bothers you, bags, RAS or Timbrens/Sumo Springs.  

 

Just to be clear on the wheels/tires, the ZR2 is only optioned with 18 inch wheels only with a 275/70R18 tire.  If you got 20s, sounds like they were from a Trail Boss?  Or someone swapped 20s on to a ZR2.

I believe my truck rides alot better than my 15 or 18. Maybe because the springs are softer.  I know that when I lowered my spare tire down and lifted it up, I was surprised how much the truck sagged just from installing the spare tire, I watched the rear bumper go down as I lifted the spare tire back in place.  I can't say the springs are adequate or not, but they seem to have "settled" over time.

I went to Chevy's website before posting.  I find it interesting that now you're changing your story from what you posted in your original post.
