2021 GMC 2500HD AT4 on 37s
Wanting to level or lift my lml. Ready lift, fabtech and cognito all make systems yet they utilize different parts to achieve the proper steering and cv angles. I want my truck to be able to tow/haul like stock. The fabtech incorporates new steering knuckles while the others don't. Readylift and suspension maxx use differential lowering kits as part of their lift/ level. Just looking for help working through these kits differences and what is best for my truck. Thanks guys!
