Description
Rubicon Express is proud to announce the introduction of new 3.5" Progressive Coil Lift systems for the Jeep Wrangler JK. These easy to install systems deliver impressive off road performance and value without having to change driveshafts, modify exhaust or brake lines. Rubicon Express’ new Progressive Coils for the JK Wrangler allows for a lower center of gravity to provide better handling on the street with increased stability in off-camber situations. The coils feature longer extended lengths when compared to linear rate coils, providing full articulation without unnecessary height. The progressive coil spring rate also results in a smooth ride over small bumps but with enough spring rate to prevent harsh bottoming during full compression. Available with or without custom tuned gas charged shocks. Unleash the potential of your Jeep with this no compromise suspension system.
Details
  • Low center of gravity allows for full articulation and improves high speed performance on- and off-road
  • Reduces the chance of roll-over in off camber situations with low gravity center
  • Progressive coils have a longer extended length vs linear, maximizing droop travel
  • Softer rate at full extension and stiffer rate at full compression helps adapt to terrain changes
