KRYPTONITE SHOCK EXTENSION KIT 2011-2022

If you’ve leveled your 2011–2026 Silverado or Sierra HD, you’ve likely reduced your available droop travel without realizing it. The factory shock becomes the limiting factor, causing the suspension to top out early and creating a harsher ride over dips, uneven terrain, and everyday road imperfections.

The Kryptonite Shock Extension Kit is designed to correct that issue by spacing the upper shock mount to provide up to 1” of additional shock length. This allows your factory-length or OE-equivalent shocks to cycle through more usable travel, restoring droop that is lost when adding a leveling kit.

When paired with Kryptonite or other aftermarket upper control arms, this kit allows the suspension to fully utilize the improved geometry and travel range. The result is better ride quality, improved front-end compliance, and reduced stress on your shocks during normal driving and off-road use.
