TRZ Motorsports Billet Upper Ball Joints - 0° Angle - Stock Length - 1 Pair (5108 / K5108) - UBJH0-1
Precision Billet Upper Ball Joints for 5108 / K5108 Applications
The TRZ Motorsports Billet Upper Ball Joints are engineered for cars using the 5108 / K5108 upper ball joint platform, including popular GM muscle car and drag racing platforms such as the 1967 - 1969 Camaro, 1964 - 1974 Nova, and 1964 - 1972 A-body. Each pair is CNC-machined in-house for maximum precision and strength, providing a major upgrade over OEM-style ball joints.
These stock-length 0° angle ball joints are ideal for vehicles at stock to mildly lowered ride heights, where maintaining proper A-arm angle and ball joint articulation is critical. Built using 6061 billet aluminum housings, 17-4 stainless studs, and stainless Teflon-lined COM bearings, they deliver smooth travel without the need for rubber boots.
Each kit includes all required hardware - castle nuts, cotter pins, and Grade 8 fasteners - making these a bolt-in upgrade for aftermarket upper A-arms designed for the 5108 / K5108 interface.

Frequently Asked Questions
When should I choose the 0° angle version?
The 0° option is best for stock or slightly lowered cars where the upper A-arm sits close to level at ride height.
Do these work in factory upper A-arms?
No. These are designed for aftermarket upper A-arms that use the 5108 / K5108 ball joint interface.
