MetalCloak has perfected dual-rate coils for the Jeep market, providing stable off-road articulation, incredible on-road handling, and excellent load-carrying capabilities. Our True Dual Rate™ coils provide increased ride height and improve handling compared to standard performance.

MetalCloak 4xE Coil Isolator polyurethane pads are designed for durability and superiority over factory parts. The pads are specifically made for MetalCloak True Dual Rate coils and are model-specific.

MetalCloak "components" have been FMVSS safety certified in a configuration with 37-inch tires, full body armor, and lifted 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 heat process during powder coating can alter the metallurgical properties of the coils, resulting in a loss of lifting properties. Therefore, the powder coating process voids any warranties specified or implied regarding the coils.

Note: After installing MetalCloak suspension, it is recommended to have a suspension specialist adjust the Jeep's suspension.
