Frequently Asked Questions
What is the RKRRK07014P?The Rock Krawler RKRRK07014P is a pair of triple rate front coil springs providing 2.5 inches of lift for the 2018 to 2026 Jeep Wrangler JL two-door and JLU four-door. They are a direct bolt-on replacement engineered for the JL platform coil spring mounts.
Does the RKRRK07014P fit the Jeep Wrangler JL Rubicon?Yes. The RKRRK07014P is designed for the full 2018 to 2026 JL and JLU lineup including Sport, Sahara, and Rubicon trim levels. Note that Rubicon models have a higher factory ride height from the factory, so final lift results may vary slightly by base trim.
What rear spring pairs with the RKRRK07014P on a JL?Rock Krawler's RKRRK07015P rear coil spring is the matched rear companion for the RKRRK07014P front spring, designed to provide correct vehicle rake and geometry for a complete 2.5 inch JL lift system.
Is the RKRRK07014P compatible with the 2022 and newer Wrangler 392 V8?The RKRRK07014P is designed for 2018 to 2026 JL and JLU models. Verify compatibility with Rock Krawler for the 392 variant, as the heavier 6.4L V8 engine may require different front spring rates for correct ride height and handling.
Do I need a track bar relocation with the RKRRK07014P on a JL Wrangler?At 2.5 inches of front lift on the JL, a track bar relocation bracket is commonly recommended to correct front axle centering. Rock Krawler and other manufacturers offer JL-specific track bar drop brackets compatible with this lift height.
Will the RKRRK07014P cause rubbing with 35 inch tires on a stock JL body?A 2.5 inch front lift on the JL with 35 inch tires generally clears at full steering lock on a stock body, though slight fender liner trimming may be required depending on tire width and wheel offset. Verify clearances with your specific wheel and tire combination.
Does the RKRRK07014P work on the Jeep Wrangler 4xe hybrid JLU?The 4xe JLU shares the same front coil spring mounts as standard JLU models but is heavier due to the battery pack, which may affect final lift height. Consult Rock Krawler for 4xe-specific spring recommendations before ordering the RKRRK07014P.
What shocks does Rock Krawler recommend with the RKRRK07014P?Rock Krawler recommends using extended travel shocks appropriate for 2.5 inch lift to maximize the available axle travel from the triple rate spring. Contact Rock Krawler or Black Ops Auto Works for specific shock recommendations for your JL build.
