Our Performance 2.0 LSC kit for the 11-19 Chevrolet/GMC 2500/3500 HD’s takes our FOX leveling kit to the next level. We utilize the same Camburg 1.25" uniball upper arms but combine them with FOX’s 2.0 Performance LSC Series front and rear shocks. This combination of parts not only improves the ride and handling on-road but more so off-road with the larger diameter shocks and remote res. for added oil capacity and cooling. The LSC compression adjusters give you the ability to fine tune the ride softer or firmer depending on how you’re using your truck. With the upper arms these shocks increase wheel travel and give you the ability to adjust the factory torsion keys to lift the front end all while improving the ride. Aftermarket torsion keys are not needed and are a waste of. Improved ride both on and off-road Eliminates weak upper ball-joint Increased wheel travel Corrected suspension geometry Compression shock adjustment Made in the USA 1-2" lift Improved ride and handling Increased wheel travel Made in the USA.
