Description:

Built for the Toughest Conditions.

The Kryptonite SS Centerlink Upgrade is engineered to dominate in strength and performance. Based on the proven design from the H1 Military Hummer, this heavy-duty centerlink outperforms anything available from the factory on non-Hummer GM HD trucks. It’s the perfect solution for drivers looking to strengthen their steering system while maintaining factory geometry and alignment specs.

This centerlink upgrade kit is designed for use with Kryptonite Tie Rods only. It comes complete with new inner tie rod ends and is compatible with both OEM and aftermarket idler and pitman arms.

This is not just an upgrade—it’s a serious steering overhaul built for lifted, worked, and abused GM HD trucks.
