Detailed Product Description

The Rancho RS999901 suspension strut and coil spring assembly is designed specifically for select Chevrolet and GMC models such as the Avalanche, Sierra 1500 Limited, Silverado 1500 LD, Suburban 1500, Tahoe, Yukon, and Yukon XL 1500. Featuring a compressed length of 13.81 inches and a travel length of 4.25 inches, this assembly ensures proper suspension articulation and ride quality. The SS7 body type provides a robust structure with a body length of 13.31 inches and an extended length of 18.06 inches, accommodating the dynamic demands of full-size trucks and SUVs.

Both upper and lower mounts utilize loop bushing mounts with a 5/8" bushing inner diameter and 1.5/16" overall length, ensuring secure and vibration-resistant installation. The 2.13-inch reserve tube diameter contributes to the assembly's durability and heat dissipation during operation. Note that this assembly does not include dust shields or bumper stops, focusing on core suspension functionality.

Common Applications and Problem Solving

  • Restores factory ride height and suspension geometry on Chevrolet Silverado 1500 and GMC Sierra 1500 models
  • Replaces worn or damaged strut and coil spring assemblies causing poor handling or uneven tire wear
  • Addresses suspension sagging or bottoming out in Chevrolet Tahoe and GMC Yukon XL vehicles
  • Improves ride comfort and stability for heavy-duty use in trucks like the Chevrolet Avalanche and GMC Sierra 1500 Limited
  • Eliminates noise and vibration issues related to deteriorated bushings in the suspension system

Installation Notes and Tips

  • Ensure compatibility with your specific Chevrolet or GMC model year before installation
  • Use proper tools to remove and install loop bushing mounts securely
  • Inspect related suspension components such as control arms and sway bar links during replacement
  • Professional alignment is recommended after installation to maintain proper handling and tire wear
