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!
