Description:
The Kryptonite 12mm Heim Steering Hardware Kit is built for riders who demand more strength than the factory setup can provide. Upgrading from the OEM 10mm pin to a heat-treated 4140 chromoly 12mm design significantly increases shear strength and reduces the risk of failure under aggressive steering loads.
Designed specifically for tie rods using a 5/8” through-hole heim joint, this kit includes precision CNC-machined components and high-misalignment spacers to maintain proper articulation without binding. Metric Grade 10.9 hardware ensures secure clamping force, while the durable zinc-plated finish protects against corrosion in harsh off-road environments.
If you’re building a custom heim steering setup or upgrading an existing system, this kit delivers the strength, precision, and reliability required for serious trail riding, racing, and hard use.
