2020 Silverado rear blocks

[Rfg14silverado]

I’m looking to do a 2.25” leveling kit in the front and also want to add a 1” block in the rear but I can’t find any 1” lift blocks for 2019-2020. Does anyone know if the Blocks from previous years work?

I believe they already have a 1.25 block stock, so this 2.25 block from readylift.com will give you the 1" you are looking for.

I have a set of factory blocks somewhere That will work. Any of the old blocks will work, just need longer u bolts.

My truck is a 2020 rst 6.2L 4wd.  Has no block from the factory

None of these trucks have blocks, its totally different from the previous style. The only ones that do are the gm lift trucks like the trailboss or at3.  I have a 1 inch block and u bolt kit from motofab in the classifieds, still new in the box.   I called to order it, they didnt have the 19-20 on the site yet.

 

I didnt use it since I put on a 3 inch icon instead.

This is quite interesting.  My 2019 didn't have factory blocks either but it has little 1/4" thick tapered shims.  Yours doesn't have them.  ReadyLift told me to remove them and I was hesitant to do so because everyone else with same lift has them still installed.

Suspensionmaxx is the only I have found to have a 1.5 block with a shock extender.  I decided just to go with the ready lift  2” front,  still have 1/2 rake.  There were/are no other blocks that I’ve found for the Denali with Arc. Would like a 1 inch at some point.

What are you doing for wheels and tires? I was thinking of getting the 3" Fabtech or 3-1/2" RC but both of those say aftermarket wheels only and I am not ready to pull the trigger on any wheels just yet. I also do not want my wheels/tires sticking out like roller skates.

That’s weird. I was starting to think they forgot to add a block in mine.   My truck is only 1.25” lower in the front than the rear 

so a 2.25” in front and 1 block  would be a nice lift/level

I put a 1.5 block in the rear when I did my 3 inch. It's not tapered so I left the shim in. No vibrations and so far so good.

 

Both the 3 inch and 3.5 come with upper control arms. With stock wheels they rub the tire. When I put my icon  coilovers on I used rough country upper arms, the tire clearance with stock wheels was about 3/16. Not enough for me. I put on 1/4 spacers up front and it's good to go.

I have ReadyLift UCAs with their 4".  I have about 1/4" clearance between tire and arm.

Interesting my 2020 doesn’t have the leaf spring block nor does it have this 1/4” shim either and I have a low speed vibration between 28-10 mph. I am thinking this forward 1/4” shim would fix my pow speed vibration

I have a 1" block on mine that came from performancelifts.com  https://performancelifts.com/fabtech-2019-current-silverado-sierra-1500-1-block-u-bolt-kit.html

Where did you get your 1.5" block?
