Skyjacker 21-24 Jeep Wrangler Rubicon 392 2in. Rear Dual Rate Long Travel Coil Spring Set

Starting with 5160H chromium alloy material, these Skyjacker rear coil springs are built for your 2021-2024 Jeep Wrangler Rubicon 392. They feature a unique dual-rate design, meaning they have two distinct spring rates. The first stage, or Flex Rate, is softer and engages when the suspension drops to full droop. This helps keep the spring seated and your tires in contact with the ground, which is crucial for off-road traction. Once compressed past this initial flex, the second stage, or Ride Rate, engages for a more controlled response.

The manufacturing process includes shot peening, where the steel is blasted with hard pellets at high velocity. This compresses the surface of the steel, increasing its tensile strength and making the spring more durable. They are also preset by compressing them completely until the coils touch, which removes stress and prevents sagging over time. This ensures a consistent ride height and performance. A baked-on powder coat finish adds a strong protective layer against corrosion.

These rear coils are designed to be side-specific, accounting for the Wrangler's particular suspension handling characteristics. This attention to detail means you get improved off-road handling without sacrificing a comfortable ride on the street.
