Kryptonite Torsion Bar Adjuster Kit KRKN11 | 2011-2026 6.6L Duramax

Upgrade or replace the factory torsion key adjustment hardware on your 2011+ Chevrolet Silverado or GMC Sierra 2500HD/3500HD with this heavy-duty Kryptonite adjuster bolt and key stop kit. Designed as a direct replacement for the factory components, the kit combines high-strength Grade 10.9 hardware with forged key stops for dependable performance in stock, leveled, and compatible lifted applications.

Kryptonite widens the retention cuts in the key stops to provide additional angular movement when used with leveling kits and non-torsion-bar-drop lift kits. This design helps keep the adjuster bolt better centered in the torsion key as suspension geometry changes, reducing unnecessary stress while retaining the available torsion key adjustment range.

Both the 14mm adjuster bolts and forged key stops feature a gold zinc coating for increased corrosion resistance and long-term durability. Whether replacing worn factory hardware or optimizing an existing suspension setup, this kit provides a durable, straightforward upgrade for GM HD trucks.
