Lift kit with spacers question.

[BigDaddyG]

Guys,

I have searched 4 inch lift etc on here, didn't really find anything. Below is my question. if there is a thread, direct me to it and I apologize in advance.

I have a 2021 Sierra AT4 6.2L. I am installing a 4" RC lift kit, Fuel Covert 20x10's -18os, 35x12.50 Toyo MT. Anybody have a setup like this or close?

Do I need spacers? Some builds show with, some show without. Are people using them to help with the fitment of the tire/wheels, or are they simply using them for a slightly wider stance?

If you do you spacers, what brand are most GM guys running? I know enough about spacers to know better than to go cheap.

Thanks in advance guys.

Custom wheel offset is what is confusing me. Some builds similar use spacers, others do not. I will checkout the other. Thanks for the info.

In that case it depends on the wheel size, backspacing, tire height and width. Good luck.

Would love to add a 4” lift to mine also. I just can’t get to where the smaller tires don’t bother me. Can’t wait to see the route you go and see some pics!

The 4" lift on an AT4 will be the equivalent to a 6" lift on a standard Sierra/Silverado 1500. The only issue with the 2019+ models is the brake caliper has the protruding piece that sticks out towards the wheel. Some people have had issues with wheels not fitting correctly bc of this. Custom Offsets recommend 0.375in bora spacers on most wheel purchase for these trucks, which is what I did and have plenty of clearance. I'm running a 2019 AT4 w/ BDS 2.5" Coilover kit on 33x12.5x20 on 20x10 w/ -19 offset. I had rubbing issues in the front so I removed the valance, cut the valence screw tabs, and tucked the wheel well liner forward on the front of the truck. Still have miner rub in the front at full crank due to the mud flaps. Waiting on the mudflap delete pieces to come in the mail and that will fix that.
