2011-2025 Duramax Shock Extension Kit (KRSE11)

Note: Excludes 2024+ AT4X/ZR2 with DSSV shocks.

Unlock your GM diesel truck’s suspension potential with the Kryptonite Shock Extension Kit. Retain factory shocks while gaining full down travel for smoother off-road performance. Perfect for leveling or mild lift setups without compromising ride quality.
