TRZ Motorsports Billet Upper Ball Joints - 10° Angle - Stock Length - 1 Pair (5108 / K5108) - UBJH10-1
High-Angle Billet Upper Ball Joints for Ultra-Low 5108 / K5108 Applications
The TRZ Motorsports 10° Angle Stock Length Billet Upper Ball Joints are engineered for aggressive, ultra-low ride height setups where the upper A-arm sits at a steep uphill angle at static height. Designed specifically for vehicles that use the 5108 / K5108 upper ball joint style, these units maintain proper articulation and help prevent binding on low-slung drag and street/strip builds.
With a built-in 10-degree stud angle, these ball joints allow smoother travel and better geometry for radically lowered cars. Each assembly is machined 100% in-house using 6061 billet aluminum housings, 17-4 stainless steel studs, and Teflon-lined stainless COM bearings for maximum durability. No boots required - these are built to take race abuse.
While extended-length versions improve camber curves, this stock-length version is ideal when you want the 10° correction without altering control arm height or suspension positioning.

Frequently Asked Questions
Who should choose the 10° angled version?
Anyone running a very low ride height where the upper A-arm is angled sharply upward at rest. The 10° angle prevents bind under compression.
Does the 10° angle reduce suspension travel?
It may reduce extension travel depending on your arm and chassis geometry. It is optimized for low stance cars prioritizing compression movement.
