Construction & Design

Each coil spring is crafted from premium 5160H chromium alloy steel, known for its exceptional strength and resilience under demanding conditions. The manufacturing process includes shot peening, where high-velocity steel pellets compress the spring surface to increase tensile strength and resistance to fatigue. Additionally, the springs undergo a presetting process that compresses them to solid height, eliminating initial sag and ensuring consistent ride height and performance throughout their lifespan.

The side-specific design accounts for the Jeep Wrangler’s rear suspension characteristics, optimizing handling and articulation. A tough powder coat finish provides a protective barrier against rust and corrosion, extending the life of the springs even in harsh environments.

Installation & Fitment

This coil spring set is a direct fit replacement for the rear suspension of 2021 through 2024 Jeep Wrangler models equipped with the 6.4L 392 engine. Installation requires standard suspension disassembly and reassembly procedures. No additional modifications are necessary, making it a straightforward upgrade for experienced mechanics or professional installers. Proper installation ensures optimal spring performance and vehicle safety.
