What It Helps Address

• Rear sag from frequent cargo or passenger loading
• Reduced rear suspension support under heavy hauling conditions
• Excessive body movement when the vehicle is loaded
• Uneven ride height caused by worn rear coil springs
• Handling instability in rear-heavy operating conditions

Installation Notes and Tips

Install on the rear suspension only and verify vehicle year, make, and model before ordering. Inspect related suspension components such as shocks, mounts, and bushings during spring replacement. Because spring compression is required for service, use proper suspension tools and follow factory repair procedures.
