True Dual Rate™ coil springs for the Jeep JL Wrangler are made from a high-strength chrome-silicon steel alloy that outperforms typical aftermarket coil springs in terms of extended length, ride quality and long-lasting durability. These springs were developed specifically for the JL Wrangler.

Our True Dual Rate™ coils provide raised ride height and improved handling over standard performance. MetalCloak 4xE Coil Isolator polyurethane pads are designed for durability and superiority over factory parts. The pads are made specifically for MetalCloak True Dual Rate coils and are model specific. MetalCloak’s “components” have been validated by FMVSS safety certification in configurations with 37-inch tires, full body armor and raised suspension. Note: True Dual Rate Coils are designed to work best with Duroflex control arms and 6Pak or RockSport shocks. Note: MetalCloak does not recommend powder coating True Dual Rate coils. The baking process during powder coating can, in some cases, change the metallurgical properties of the coils, resulting in a loss of coil lift. Therefore, the powder coating process of the coils voids any warranties stated or implied with respect to the coils. Note: We recommend that a suspension specialist adjust your Jeep’s suspension after installing the MetalCloak suspension.
