Rock Krawler Suspension RK07987P 3.5 Inch Triple Rate Front Lift Coil Spring for Jeep Wrangler JLU Rubicon 392

The Rock Krawler RK07987P is a high-performance front coil spring engineered specifically for the Jeep Wrangler JL Unlimited (4-Door) Rubicon 392. This triple-rate progressive coil spring provides approximately 3.5 inches of front lift, designed to work with the heavier weight and higher factory ride height of the 392 V8 platform.

Key Features:

• Triple-rate progressive spring design for superior ride quality and load handling across varying terrain conditions
• Engineered specifically for JLU Rubicon 392 models to accommodate the added weight of the V8 engine
• Black powder-coated finish for corrosion resistance and durability
• Increases ground clearance to accommodate larger tires and improve off-road capability
• Application-specific design minimizes spring settling and maintains consistent ride height
• Delivers approximately 3.5 inches of front lift above the factory 392 suspension
• Backed by a 5-year manufacturer warranty

Rock Krawler coil springs are manufactured from high-quality spring steel and designed to provide the perfect balance between on-road comfort and off-road performance. The triple-rate design allows the spring to progressively increase resistance under compression, ensuring excellent articulation on the trail while maintaining stability during daily driving. Note that 392 lift heights result in a ride height approximately 1 inch taller than the same-lift configuration on a V6 Wrangler Rubicon due to the factory lift differences.
