About this kit

1.5-2 Inch Leveling Kit with M1 Monotube Shocks (2020-2025 HD), fitment-checked

Two parts, one box: Rough Country 959440 combines leveling kit 9594 — the forged torsion bar keys that set 1.5-2 inches of front lift — with M1 Monotube shock pair 770795P. It covers 2020-2025 Chevrolet Silverado and GMC Sierra 2500 HD and 3500 HD in 4WD and RWD, but not AT4X or ZR2 trucks running Multimatic DSSV dampers.

The 1.5-2 inch front lift in this package comes from kit 9594's forged torsion bar adjuster keys, with M1 Monotube shock pair 770795P included to handle damping. Listed applications run across the 2020-2025 Chevrolet Silverado 2500 HD and 3500 HD and GMC Sierra 2500 HD and 3500 HD, both drivetrains, from WT and Pro up to Denali Ultimate. Installation is fully bolt-on, with no cutting or welding. AT4X and ZR2 trucks are not supported. Shipping weight: 25.58 lb.

What’s in the box

Kit contents

Priced components are sold separately here, so a worn shock or arm can be replaced on its own later.

Rough Country shares subassemblies across kits, so individual package labels can carry broader application ranges. The complete 959440 kit fits the vehicles shown in the fitment section above.
