Rock Krawler 07-18 Jeep Wrangler JKU 4DR 1.5in Lift Triple Rate Coil Springs - Rear

These are the rear triple rate coil springs from Rock Krawler, designed specifically for the 2007-2018 Jeep Wrangler JKU 4-door models. They are built to give your Jeep a 1.5-inch lift, which is a popular height for owners looking to fit slightly larger tires or improve ground clearance without going for a full suspension overhaul.

What makes these springs stand out is their triple rate design. This means they have three distinct spring rates within a single coil. The initial rate is softer, providing a comfortable ride on the street and allowing the suspension to articulate well over smaller obstacles. As the spring compresses further, it engages a stiffer rate, controlling body roll during cornering and handling larger impacts. The final, most aggressive rate comes into play during extreme compression, offering robust support and preventing bottoming out. This advanced spring rate setup is well-built and aims to balance on-road comfort with off-road capability.

Installing these rear springs is a common step for JKU owners wanting a modest lift. They are designed to fit directly onto your existing suspension setup, making them a straightforward upgrade for improving your Jeep's stance and performance.
