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.\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\n\u003ch3\u003eInstallation \u0026amp; Fitment\u003c\/h3\u003e\n\u003cp\u003eThis 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.
