This Duramax stage 4 leveling kit is a great addition to your 2020 - 2025 GMC/Chevrolet HD 6.6L Duramax. To use it, first, make sure your vehicle is not an AT4X or ZR2 truck with DSSV shocks as it won't fit. When installing, follow the provided instructions carefully. The adjustable torsion key allows you to get a lift of 1 to 2 inches in the front. You can install the included Kryptonite parts like upper control arms, ball joints, and sleeves to complete the setup. For maintenance, regularly check the shocks for any signs of wear or leaks. Also, keep an eye on the alignment pins and cam bolt kit. If you notice any issues with alignment or the parts seem bent or damaged, replace them as needed. Remember, don't adjust the lift more than 2 inches over the stock height, or you might end up with front shock failure.
