Skyjacker 4" Rear Leaf Springs for Jeep (1974-1988)

Upgrade the rear suspension of your Jeep J10, J20, or Wagoneer with these robust 4-inch rear leaf springs from Skyjacker. Designed for models from 1974 to 1988, these springs offer a significant lift while enhancing both load-carrying capacity and ride comfort, making them ideal for work, play, and everything in between.

Experience Skyjacker Softride® Technology

These rear leaf springs feature Skyjacker's advanced Softride® technology, ensuring superior performance and durability. The individual spring leaves are constructed from high-quality American steel and undergo a critical shot-peening process. This technique involves bombarding the steel with high-velocity pellets, compressing its surface and dramatically increasing its tensile strength. This results in springs that are more resistant to fatigue and breakage, allowing for maximum wheel travel and a smoother ride without compromising longevity.

Key Benefits:

  • Lift Height: Provides a 4-inch rear suspension lift
  • Vehicle Fitment: Compatible with 1974-1988 Jeep J10, J20, and Wagoneer models
  • Durable American Steel: Ensures strength and long-lasting performance
  • Shot-Peened Leaves: Increases tensile strength and resistance to stress
  • Bolt-Style Spring Clips: Eliminates friction and binding for a smoother, quieter operation
  • Tapered Leaf Ends: Promotes better flex and more even load distribution

Skyjacker distinguishes its springs by using bolt-style spring clips, which prevent the friction and binding associated with traditional cinch-style clips. The innovative tapering of the leaf ends further enhances performance by allowing for greater flex and distributing loads more evenly across the spring. This design reduces stress points and contributes to a more comfortable and controlled ride. Equip your Jeep with Skyjacker rear leaf springs for a noticeable improvement in performance and comfort.
