Description

The Tuff Country 10891 Rear Ladder Bar Kit is a heavy‑duty upgrade designed for 1973–1987 GMC and Chevy K1500 4WD half‑ton pickups. This pair of ladder bars is engineered to reduce axle hop and spring wrap, delivering more consistent traction and cleaner launches.

  • 1 1/4" steel tubing: Built from robust, thick‑walled steel for lasting strength under load and braking forces.
  • Custom-fit for 1973–1987 GMC/Chevy K1500 4WD: Precisely matched to the rear suspension geometry of these classic trucks for straightforward alignment.
  • Powder-coated finish: Durable coating protects against corrosion and road grime, keeping the setup looking clean longer.
  • Includes all mounting hardware: Everything needed for installation is provided in the kit.
  • Installation note: Will not fit saddle tanks: Important compatibility detail to ensure proper fitment with your fuel configuration.
  • Sold as a pair: Complete rear ladder bar set designed to work together with your truck’s leaf‑spring rear suspension.

By limiting axle wrap and reducing spring wrap, these ladder bars help keep tires planted for improved traction during acceleration and hard driving. The result is steadier launches, more predictable handling, and enhanced overall drivetrain response. The 1 1/4" tubing and powder‑coated finish ensure durability for daily use, light off‑road excursions, and nostalgic restorations alike. This kit is an ideal upgrade for 4WD owners looking to restore planted rear performance on older GM and Chevy trucks.
