Front Upper A-Arm Heim Joint Upgrade DIY Kit Fits: Wildcat XX (2018–Current) and Tracker XTR
Tired of replacing worn-out spherical bearings in your front upper A-arms? Our DIY Heim Upgrade Kit is the ultimate solution for riders looking to increase durability and performance on the trail or track. This upgrade converts your OEM-style outer pivot to a traditional FK heim joint, offering increased strength, longevity, and serviceability.
The factory cast bearing housings are known weak points, often cracking under stress. Our upgrade replaces them with precision-engineered 4130 chromoly weld-in bungs and premium FK rod ends, giving you a more rugged and reliable suspension system.

(2) Custom 4130 Chromoly Weld Bungs
(2) FK Bearings Rod Ends
(2) Jam Nuts
(4) Custom Stainless Steel High-Misalignment Spacers (Compatible with OEM Hardware)
