Rock Krawler RK07844K 3.5" Rear Coil Spring Kit for Diesel Wrangler JL/JLU

The Rock Krawler RK07844K is a 3.5-inch rear coil spring kit engineered specifically for the added weight of the diesel engine found in 2018-present Jeep Wrangler JL 2-Door and JLU 4-Door models. Rock Krawler designs these coil springs with a triple spring rate to maximize effective suspension travel, deliver a quality on-road ride, and ensure the springs never unseat at full droop during off-road flex.

Key Features:

• Provides 3.5 inches of rear lift calibrated for diesel-engine Wrangler weight
• Triple spring rate design balances street comfort with trail performance
• Engineered to minimize settling over time for consistent lift height
• Includes rear spring correction pads to address coil bow and vehicle lean
• Paired springs of equal length for consistent left-to-right ride height
• Designed exclusively for 3.0L EcoDiesel and compatible V8-swapped Wranglers — not for standard gas models

What's Included:

• (2) JL rear coil springs
• (2) JL rear spring correction pads

Rock Krawler coil springs are engineered and built in Latham, New York, and are designed as a standalone rear upgrade or as part of a complete Rock Krawler suspension system. Lift heights are based on Rubicon models in a standard build configuration. If running a spare-delete setup, consider dropping 1 inch in rear coil lift height; for overland or heavily upfitted builds, consider sizing up 1 inch in the rear.
