3.5IN SUPRFLX PC KIT 2DR W/MONO RES

Rubicon Express introduces new 3.5" Progressive Coil Lift systems for the Jeep Wrangler JK. These easy-to-install systems offer impressive off-road performance without requiring driveshaft, exhaust, or brake line modifications. Rubicon Express's Progressive Coils for the JK Wrangler provide a lower center of gravity for improved street handling and increased off-camber stability. The coils feature longer extended lengths than linear rate coils, maximizing articulation without excessive height. The progressive coil spring rate ensures a smooth ride over small bumps while preventing harsh bottoming during full compression. Available with or without custom-tuned gas-charged shocks, this system unleashes your Jeep's potential.
