Give your 2011–2019 GM HD a true 6-inch stance and room for larger tires with a Pro Comp system built for strength, geometry, and daily drivability. Purpose-built components correct CV and steering angles on these IFS/torsion-bar trucks while heavy-duty crossmembers and knuckles add durability for work or weekend trails.
