Feature:
Performance Tuned Valving– Vehicle-specific damping to control steering feedback and reduce bump steer
2.0” Aluminum Body – Dissipates heat faster than steel for consistent performance under load
Internal Floating Piston (IFP) – Separates oil and nitrogen gas to prevent fade and maintain damping control
6061-T6 CNC Machined Components – Precision-built for strength, durability, and long-term reliability
Robust Seal Pack System– Multiple seals protect against contamination and extend service life
Heavy-Duty Fabricated Steel Construction – Built to handle the added stress of oversized tires, rough roads, and demanding use without flexing or deformation

Description:
In 2015, GM moved to an electronically assisted steering system on their HD trucks and eliminated the factory steering stabilizer entirely. While the updated steering system improved overall steering effort and responsiveness, real-world driving showed there was still noticeable feedback transferred through the steering wheel, especially on trucks running larger tires, aftermarket wheels, leveling kits, and upgraded suspension components.
After extensive testing, we found that adding a properly matched steering stabilizer significantly improved steering feel, stability, and driver confidence, even with the factory electronic assist steering system. While GM designed these trucks around stock wheel and tire setups, many HD owners demand more from their trucks both on and off-road.
Developed in collaboration with FOX, this kit combines a proven FOX 2.0 Performance Series stabilizer with a heavy-duty Kryptonite fabricated mount engineered specifically for trucks not equipped with factory stabilizer tabs. The result is improved steering control, reduced shimmy and road feedback, and a more stable, predictable driving experience.
The FOX aluminum body stabilizer features an Internal Floating Piston (IFP) design for consistent damping performance and fade resistance under demanding conditions. Combined with Kryptonite’s fabricated steel mounting system and easy-install slotted bracket design, this kit delivers a clean, durable solution for leveled and lifted GM HD trucks running larger wheel and tire combinations.
