First off, wanna say this forum has been very informative. I’m ordering a 2021 GMC 3500 AT4 diesel and I wanna get it lifted. I’m torn between the Cognito 4 inch performance lift and the BDS 6.5 lift. I like the fact that the Cognito comes with the UCAs, idler and pitman arms but, I like the warranty of the BDS. I’ve called both companies and was told that they have not tested their lifts on 2021s yet, but how much could the suspension change between years? They didn’t redesign the suspension between last year and the 2021 that I’m aware of. I’ve got the rims and tires (Fuel Vapor 20x9 with 1mm offset and Fuel Gripper AT 37x12.50 R20) picked out. I also would like to do the least amount of trimming as possible. I don’t wanna do a leveling kit, I would like to keep the ride as best as possible. I did a leveling kit (UCAs keys shocks) on an 2500 avalanche and I didn’t care for the ride, so a leveling kit is out of the question. Pros, cons on either one of these would be greatly appreciated. Thank you in advance. Sent from my iPhone using Tapatalk
