Description

Upgrade your lifted Chevy or GMC 4×4 with the Tuff Country 75171 Rear Dual Shock Kit. This bolt-on solution adds a second shock on each rear corner for enhanced damping and greater control when running large tires.

  • Dual rear shocks per side: Adds an additional shock on both the driver and passenger sides to boost damping and stability on lifted 4WD trucks.
  • Bolt-on installation: Designed for straightforward mounting with no complex fabrication required; includes all necessary mounting brackets and hardware.
  • Included mounting components: Robust brackets and hardware designed to align with the factory rear suspension points for reliable performance.
  • Vehicle compatibility: Fits 1973–1987 Chevy Blazer 4WD, 1973–1987 Chevy Suburban K1500 4WD, 1973–1987 Chevy Truck K1500 4WD (1/2 ton), and corresponding GMC models such as GMC Jimmy 4WD, GMC Suburban K1500 4WD, and GMC Truck K1500 4WD (1/2 ton).
  • Shocks sold separately: The kit provides the mounting hardware for dual rear shocks; choose compatible shocks separately to complete the upgrade.
  • Durable construction: Built to withstand off‑road use and daily driving, delivering consistent performance across varied terrains.

Designed by Tuff Country, a brand with a legacy of durable suspension upgrades, this kit expands your truck’s dampening capacity without altering overall ride height. By distributing damping across two rear shocks, you’ll experience more controlled compression and rebound, improved tire contact, and steadier handling when navigating rough roads, trails, or highway grooves with larger tires.
