TRZ Motorsports Billet Upper Ball Joints - 0° Angle - Stock Length - 1 Pair (5208 / K5208) - UBJH0-2
High-Strength Billet Upper Ball Joints for 5208 / K5208 Applications
The TRZ Motorsports Billet Upper Ball Joints are engineered for racers who demand superior precision, durability, and weight savings over traditional OEM-style joints. CNC-machined entirely in-house, these upper ball joint assemblies feature 6061 billet aluminum housings, 17-4 stainless steel studs, and stainless steel Teflon-lined COM bearings for long-term performance without the need for dust boots.
This version is the 0° ball joint angle option in stock length, ideal for vehicles with a stock to mildly lowered ride height. If your upper A-arm is close to level at ride height, the 0° design ensures proper articulation and geometry without overextending the stud.
Each kit includes everything needed for installation - COM bearings, castle nuts, cotter pins, and Grade 8 hardware. At only 1.75 lbs per pair, these billet joints help reduce front-end weight while improving steering precision and suspension travel capability.

Frequently Asked Questions
How do I know if I need 0° or 10° ball joints?
If your upper A-arm sits nearly level at ride height, the 0° version is correct. If your A-arm points sharply upward on very low setups, the 10° version prevents the ball joint from binding.
Does the stock-length stud increase suspension travel?
Stock length maintains factory geometry. For reduced camber change and potential additional travel, choose the extended-length option.
