Fabtech K1157M 2-3.5" Lift Kit with Ball Joint Upper Control Arms & Stealth Shocks

The Fabtech K1157M suspension lift kit delivers 2-3.5 inches of increased ride height for 2020-2021 GM 2500HD trucks, enabling fitment of 35-inch tires while providing a more level, aggressive stance.

• 2.25-inch OD x .250-inch wall DOM bushing barrels for heavy-duty applications
• Additional 1 degree of caster built in for improved steering stability and returnability
• Ball joint angle optimized to allow full suspension travel without binding

Forged Torsion Bar Keys:

• Heavy-duty forged steel construction replaces factory keys
• Provides adjustable ride height to work in conjunction with new upper control arms
• Allows fine-tuning of front suspension height within the 2-3.5 inch range

Stealth Monotube Shocks:
