2020-2025 Duramax Stage 4 Leveling Kit w/ Fox Shocks (KR20STAGE4FOX)

Fits

Note: Will NOT fit on AT4X & ZR2 trucks equipped with DSSV shocks

For those who appreciate quality and durability without breaking the bank; this stage 4 leveling kit is one of the fastest, safest, and easiest ways to get a modest 2" front lift in your Duramax. Featuring forged torsion keys that are designed to grab the “flat” of the torsion bar for a tighter, sturdier fit. And Fox shocks with superior dampening control and no harsh top-outs, are particularly effective if you plan on running larger, more aggressive tires.
