ReadyLift 4" SST | Silverado

Cobra003 · June 23, 2020

Has anyone attempted to put 35x12.50x20 on their truck with this lift?

The wheels I am looking at are 20x9 with a 1 offset or 20x10 with a -18. But ReadyLift says 20x9 0 Offset and 35x11.50. I'm assuming that requires no cutting or fabricating? I think wider is better (obviously not always the case) but its hard for me to visualize the 20x9 and 1 offset. How much poke would it have? How much cutting/fabricating would I have to do to get the 20x10 and 35/12.50's?

Wider isn't really better unless you are doing real soft surfaces.

The 4 inch kit explicitly states no off road use soo.

With the wheel wheel restrictions I would just stuck to their spefications.

Their pic is with 20x9 0 offset 295/65 R20, 11.5s

Red one is with 12.5s had to trim the wheel wheel corners with a sawzall.

Interesting that the 2" SST material for the AT4 & Trail boss doesn't state this...

ReadyLift Kits in general are not recommended for any high level of flex. Yes they can be used “offroad” at the deer lease or a dirt road but if you’re planning to go wheeling with your vehicle I strongly recommend a full suspension setup such as BDS, FabTech, Icon, etc

Not all too much. We do this at my shop pretty frequently. Most trucks it’s just fender, splash guard, and liner trimming. Some trucks require having the crash bar cut (Namely F150s) but I haven’t experienced that at all with Silverado 1500s

"This kit is not compatible with Trail Boss, AT4 or Denali editions. Use of Auto 4 Hi feature not recommended.....Note: NOT intended for off-road use or abuse."

It didn't say that a few months ago.

I assume, since we know they max out the driveline angles (reliability unknown yet), It's probably a uphill full lock off camber turn on slickrock for instance. Or if you somehow manage to flex it to where it actually picks a front and rear wheel off the ground.

still curious why ReadyLift is so insistent on not using Auto high I know the first generation autotrak xfer boxes from like 2001 era had some clutch issues. But I'm not aware of any now.
