Rock Krawler RK07729K 4.5-Inch Front Coil Spring Kit for Diesel Jeep Wrangler JLU 4-Door

The Rock Krawler RK07729K is a 4.5-inch front coil spring lift kit specifically engineered for diesel-powered 2018-and-newer Jeep Wrangler JLU 4-Door models. Designed to accommodate the added front-end weight of the diesel powertrain, these coil springs deliver a level, properly-geometried lift while maintaining excellent on- and off-road ride quality.

Key Features:

• Provides 4.5 inches of front lift tuned specifically for diesel engine weight distribution
• Triple-rate spring design delivers superior on-road comfort compared to OEM linear-rate springs
• Built with proper free-length to ensure the spring stays firmly seated in the coil bucket and maximizes off-road articulation
• Includes correction pads to eliminate the spring bow inherent in the factory setup
• Engineered for a bolt-in installation with no cutting or major modifications required
• Compatible with Rock Krawler's broader JLU suspension system lineup for future upgrades

Rock Krawler coil springs are constructed from high-quality materials rated to withstand the demands of hard-core off-road use, from rock crawling and trail running to everyday street driving. All Rock Krawler hard parts are backed by the brand's Abuse Proof Lifetime Guarantee — control arms, track bars, and mounting brackets will be replaced if bent, broken, or damaged. Springs are warranted against manufacturer's defect.
