Does anyone know who makes differential drop kit for 2019-2021 GMC Sierra 1500? I installed RC 3.5 lift kit, but there is some kind of noise coming out of somewhere in the front. and the shaft spinning sound is getting bigger and bigger.

Hi All, Newbie here in the forum.. Vehicle: 2021 GMC Sierra 1500 Denali I took the truck to the shop for 3.5 inch lift, earlier. The guy who works there said if I lift my truck, GMC is going to void my entire warranty. I wonder if this is normal? I was also told that most of the lifted trucks have transmission oil leaking issues, so I will need to install a front differential drop kit. Does GMC has such issue for only 3.5 lift? Thank you guys in advance!

@redwngr it is just for passenger and It is not for a hard core offroad. I will probably go for off road comping some times. @DustSierra I agree.. I bought 3.5 RC lift kit and Method MR701 17*9 wheels.

Hello! I got my 2021 GMC Sierra 1500 Denali(5.3l) 3 month ago and this is my first truck so I don't know too much about trucks. I wanted to lift it for about 4 inches(using lift kit) and get the black off-road wheels and tires. Just lifting no cutting.. Does anyone have the same set up like I wanted to do? I really need your help to choose lift kits, wheels and tires for my truck. Could you guys please share your experience? Thank you so much.
