Detailed Description

This suspension ball joint is designed for front upper mounting positions on a wide range of Chevrolet and GMC platforms, including P30, P20, C20, C30, G20, G30, G3500, P2500, C2500, C3500, R2500, and R3500 applications.

The steel body, rubber dust boot, and greaseable construction support routine front-end service on older GM chassis that rely on precise steering and suspension articulation. This part cross-references MOOG Chassis Products K6122 for the same application.

What It Helps Address

• Front-end looseness or play at the upper control arm connection
• Clunking or popping noises from worn suspension joints
• Uneven tire wear caused by excessive suspension movement
• Steering wander or reduced road feel on GM truck and van chassis
• Restoration of worn OE-style front upper suspension geometry

Installation Notes and Tips

Verify the vehicle’s year, make, model, and front upper position before ordering. Confirm the 11th digit of the VIN where noted for 1996 Chevrolet G30 and GMC G3500 applications. Inspect the control arm, mounting holes, and surrounding hardware for wear before installation. Use the correct 12 mm wrench size and follow factory service procedures for torque and alignment after replacement.

Quality Assurance

Dorman manufactures this ball joint as a tested replacement part for specific OE applications. The design is intended to match the original suspension fitment and service requirements for compatible Chevrolet and GMC front upper ball joint applications.
