I have a 2007 2500HD Double Cab 2WD. I installed and rotated Motofab torsion wrenches. I have 18x9 wheels wrapped in 33x10.8" Nitto tires. These arms are said to be for trucks with a torsion wedge that gives 2 additional degrees of positive camber. But I had to turn the keys all the way out to set the camber to 0. As a result, the upper wishbones rode on the frame bulge. I'll probably end up ordering the standard angle arms and lowering the keys a bit. Pretty disappointing. Hours of work on a truck and $180 for a pair. + the cost of normal weapons. live and learn You can buy an upper arm camber kit for about $40 that gives +/- 1.5 degrees if needed. Sprayed them with AT 205 Reseal to rejuvenate them. But in the near future there will be a transition to the upper control levers cognito.
