Skyjacker Rear Leaf Springs for GMC K3500: Unmatched Durability and Ride Quality

Upgrade your 1979-1986 GMC K3500 Pickup with Skyjacker's premium rear leaf springs, engineered to deliver exceptional performance both on and off the road. Built with Skyjacker's renowned Softride Technology, these springs provide a remarkable blend of rugged off-road capability and refined street comfort, ensuring your truck handles any challenge with confidence.

Engineered for Excellence

  • Superior American Steel: Constructed from high-grade American steel, ensuring maximum tensile strength and long-lasting durability.
  • Shot-Peened for Strength: Each leaf undergoes a high-velocity shot-peening process, compressing the surface to significantly increase tensile strength and resistance to fatigue.
  • Optimized Ride Comfort: The Softride Technology minimizes road shock and vibration, offering a noticeably smoother ride compared to stock springs.
  • Reduced Friction Design: Utilizes bolt-style spring clips that prevent binding and friction, allowing for smoother suspension articulation and improved wheel travel.
  • Tapered Leaf Design: Features leaves tapered along their entire length, which promotes greater flex at the ends and distributes load more evenly, enhancing both performance and lifespan.

Direct Fit for Your GMC K3500

These rear leaf springs are specifically designed as a direct replacement for the 1979, 1980, 1981, 1982, 1983, 1984, 1985, and 1986 GMC K3500 Pickup models.
