A-Premium Front Upper Ball Joints 2-Pack for Chevy & GMC — Pre-Greased with Hardware

A-Premium 2-pack front upper ball joint set replaces worn steering pivot points on compatible Chevy, GMC and Cadillac SUVs and trucks for restored steering stability and reduced suspension noise.

If your Silverado, Sierra, Tahoe, Yukon, Suburban, Avalanche, Savana or Escalade feels loose in the front end, makes clunks over bumps, or shows uneven tire wear, worn upper ball joints are a common cause. This A-Premium kit includes both left and right front upper ball joints plus hardware, pre-greased for immediate installation, and is engineered to meet the load and temperature demands of full-size GM platforms from late‑1990s through mid‑2000s model years.

What comes in the A-Premium kit and how is it prepared?

The kit supplies both front upper ball joints—driver and passenger sides—plus the small parts needed for correct assembly. Components arrive pre-greased and include castle nuts, cotter pins and circlips so you won’t need separate sealers or fasteners for a standard replacement job.

• 2 x front upper ball joints (left and right)
• 2 x castle nuts, 2 x cotter pins, 2 x circlips included
• Pre-greased with grease fitting included for future servicing

How do these ball joints perform and what materials are used?

Manufactured with steel ball studs and durable housings, these ball joints are designed for high bearing loads, thermal resilience and cold-weather reliability. A rubber bushing cushions vibration and helps reduce road noise for a quieter, more controlled ride.

• Steel ball stud for strength and wear resistance
• Rubber bushing reduces vibration and noise
• Pre-greased with optional grease fitting for re-lubrication

How will replacing these ball joints affect steering and tire wear?

Installing fresh upper ball joints typically tightens steering feel, eliminates clunks over bumps and helps restore correct wheel alignment geometry. That can reduce uneven tire wear patterns and improve predictable steering response without requiring unnecessary suspension replacement.

• Reduces loose or shaky steering sensations
• Eliminates squeaky or clunky suspension noises
• Helps prevent uneven tire wear and steering drift

Who is this for: This A-Premium 2-pack front upper ball joint is intended for DIY mechanics and professional technicians servicing GM full-size trucks and SUVs listed in the fitment. Choose this kit if you need a direct-fit replacement with included hardware, pre-lubrication, and a one-year unlimited-mileage warranty for peace of mind during routine suspension maintenance.
