Rock Krawler RK07018K 4.5" Front Coil Spring Kit for Jeep Wrangler JL/JLU

The Rock Krawler RK07018K is a 4.5-inch front coil spring kit engineered for the 2018-present Jeep Wrangler JL (2-Door) and JLU (4-Door Unlimited). Designed for serious off-road enthusiasts, these premium coil springs deliver a noticeable lift while maintaining a quality on-road ride and maximizing trail performance.

Rock Krawler's front coil springs utilize a triple spring rate design that maximizes effective suspension travel and ensures the spring does not unseat at full droop — a critical advantage during aggressive rock crawling and trail driving. The springs are precision-preset to minimize settling over time, so your lift height stays consistent mile after mile.

Kit Includes:

• One (1) pair of 4.5" lift front coil springs
• One (1) pair of front spring correction pads

Key Features:

• 4.5-inch front lift height (based on Rubicon models in standard build configuration)
• Triple-rate coil spring design for maximum travel and droop prevention
• Pre-set to minimize spring settling and maintain consistent ride height
• Compatible with both 2-door JL and 4-door JLU Wrangler platforms (2018-present)
• Engineered to support builds running larger tires and aftermarket suspension components

Rock Krawler recommends adjusting coil lift selection based on your specific build. If running a spare-delete setup, consider sizing down 1 inch in rear coil lift height. For overland or heavily upfitted builds, consider sizing up 1 inch in the rear. A new front driveshaft is also recommended for frequent off-road use at this lift height.
