FAQs

Is this a direct replacement for my factory springs?

Yes, the ROC LS8370 is designed as a direct replacement, provided your vehicle model matches the compatibility specifications.

Do I need to replace both sides at the same time?

It is highly recommended to replace leaf springs in pairs to ensure balanced handling and consistent ride height.

What tools are required for installation?

You will need a heavy-duty jack, axle stands, a torque wrench, and standard automotive socket sets for suspension removal.

Does this product come with mounting hardware?

The pack includes the leaf spring assembly; please check your specific kit contents as mounting hardware like U-bolts are often sold separately.

Can I install these springs myself?

While technically possible for experienced DIYers, suspension work involves high-tension components and should be performed by a professional mechanic.

Troubleshooting

Vehicle sits unevenly after installation

Verify that the leaf spring is seated correctly on the axle mounting plate and that all U-bolts were tightened to the same torque specification.

Increased noise or creaking

Check that the shackle bushings are properly lubricated and that all mounting bolts are secured tightly to prevent metal-on-metal friction.

Pros and Cons

Pros

  • Improved ride comfort over conventional springs
  • Sturdy construction for long-term reliability
  • Restores factory-level handling characteristics
  • Reduces suspension noise through refined design

Cons

  • Installation requires specialized mechanical tools
  • Heavy component weight necessitates assistance during fitting

Setup, Compatibility & Care

To ensure success, always cross-reference your vehicle's specific VIN or OEM part numbers with the LS8370 specifications before purchase.

Installation Steps:

  1. Secure the vehicle on a heavy-duty lift or safe jack stands.
  2. Support the rear axle independently before unbolting existing springs.
  3. Carefully remove old hardware, inspecting shackle bushings for wear.
  4. Install the ROC leaf spring, ensuring proper alignment with the axle center pin.
  5. Tighten all U-bolts to the manufacturer's specified torque settings.

Care: Periodically inspect the leaf ends and bushings for signs of dry rot or excessive movement. Keep the spring leaves free from heavy debris buildup to ensure optimal flex.
