What It Helps Address

  • Harsh ride feel from worn rear shocks
  • Noisy or inconsistent rear suspension response
  • Loss of factory-like damping on a Toyota Tundra rear suspension

Installation Notes

Verify mount style, compressed length, and extended length before installation. This shock uses a stem upper mount and a loop bushing and sleeve lower mount, so confirm the vehicle’s rear mounting points match the listed dimensions and hardware interface. Inspect surrounding suspension components, bushings, and mounting points before replacing the shock absorber.
