TRZ Motorsports Billet Upper Ball Joints - 10° Angle - Stock Length - 1 Pair (5208 / K5208) - UBJH10-2
Precision Billet Upper Ball Joints for Ultra-Low Suspension Geometry
The TRZ Motorsports 10° Stock-Length Billet Upper Ball Joints are engineered for ultra-low front suspension setups where the upper A-arm points sharply upward at ride height. The 10° angled design prevents binding, keeps the stud within its articulation range, and ensures proper suspension movement during travel - crucial for high-performance drag racing or aggressively lowered street/strip cars.
CNC-machined entirely in-house, these ball joint assemblies combine 6061 billet aluminum housings, 17-4 stainless steel studs, and Teflon-lined stainless steel COM bearings to deliver exceptional strength, smooth operation, and long-term durability. No dust boots are required thanks to the stainless bearing design.
This version features stock-length studs, which maintain OEM-style geometry and travel characteristics, while providing the angled articulation needed for low ride heights. Each pair includes castle nuts, cotter pins, and Grade 8 hardware, weighing only 1.75 lbs total.

Frequently Asked Questions
Who should choose the 10° angled ball joints?
If your upper A-arm points noticeably uphill on an ultra-low setup, the 10° joints prevent binding and offer proper articulation at ride height.
When should I choose extended length instead of stock?
Extended-length versions help reduce camber change through travel. Stock length is best for maintaining factory-style geometry while still providing the needed angle.
