TRZ Motorsports Billet Upper Ball Joints - 10° Angle - 1" Extended Length - 1 Pair (5208 / K5208) - UBJH10-2E
Extended-Length 10° Billet Upper Ball Joints for Ultra-Low Suspension Setups
The TRZ Motorsports 10° Extended-Length Billet Upper Ball Joints are engineered specifically for cars running extremely low ride heights where the upper A-arm points uphill sharply at rest. This angled design prevents the stud from approaching its limit at ride height, ensuring proper articulation and avoiding bind during suspension travel.
CNC-machined completely in-house, these ball joints combine 6061 billet aluminum housings, 17-4 stainless steel studs, and Teflon-lined stainless steel COM bearings for maximum strength and long-term durability. No boots are needed thanks to the stainless bearing design.
The 1? extended length stud helps reduce camber change through travel and may increase usable suspension movement depending on your A-arms, spindle height, and overall geometry. Each pair includes castle nuts, cotter pins, and Grade 8 hardware - everything needed for installation.
These joints fit any vehicle using the common 5208 / K5208 upper ball joint size and weigh just 1.75 lbs per complete pair.

Frequently Asked Questions
When should I choose the 10° angled version?
If your upper A-arm points significantly upward at ride height on an ultra-low suspension setup, the 10° angle prevents the stud from binding and maintains proper travel.
What advantages does the 1? extended length provide?
The extended stud helps flatten the camber curve and may increase available travel, though results depend on your exact A-arms, spindles, and suspension geometry.
