TRZ Motorsports Billet Upper Ball Joints - 10° Angle - 1" Extended Length - 1 Pair (5108 / K5108) - UBJH10-1E
Extended-Length 10° Billet Upper Ball Joints for Ultra-Low 5108 / K5108 Setups
The TRZ Motorsports 10° Angle, 1? Extended Length Billet Upper Ball Joints are purpose-built for ultra-low ride height cars that place the upper A-arm at an aggressive uphill angle at static ride height. Designed for vehicles using the 5108 / K5108 ball joint, these billet assemblies maintain proper articulation while improving camber behavior through suspension travel.
The combination of a 10-degree stud angle and 1-inch extended length helps avoid binding on slammed setups while reducing camber change during compression and extension. While travel gains depend on the user's exact suspension components, this configuration is ideal for drag cars and pro-touring builds that run very low static height.
Machined 100% in-house, these ball joints feature 6061 billet housings, 17-4 stainless studs, and Teflon-lined stainless COM bearings. No rubber boots required - these joints are built for high-load racing environments.

Frequently Asked Questions
When should I choose the 10° angled ball joint?
Choose the 10° option when your upper A-arm points noticeably uphill at ride height - common with very low drag or street/strip setups.
Can the 10° angle limit suspension travel?
Yes. While it prevents binding at ride height, the 10° angle can reduce extension travel depending on the control arm and chassis geometry.
