Rock Krawler 07-18 Jeep Wrangler JKU 4DR 3.5in Lift Triple Rate Coil Springs - Front

These are the front, triple-rate coil springs from Rock Krawler, designed specifically for the 2007-2018 Jeep Wrangler JKU 4-door models. They are intended to provide a 3.5-inch lift, giving your Jeep a more aggressive stance and increased ground clearance for off-road adventures.

The triple-rate design is a notable feature, meaning the spring has three distinct spring rates that engage at different points of suspension travel. This setup helps to offer a good balance: a softer rate for initial compliance over small bumps, a firmer rate for controlling body roll during cornering, and a heavy rate for bottoming resistance during aggressive off-road use or when carrying extra weight. This well-built spring set is constructed to handle the demands of lifted Jeep applications.

When installing these springs, remember they are designed to work as part of a suspension system. You'll want to ensure all other related components, such as shocks and sway bar links, are compatible with the 3.5-inch lift height for optimal performance and safety.
