MetalCloak 2.5" Front True Dual Rate Coils for the 2018+ Jeep Wrangler JL 392 deliver stable on-road manners and strong articulation off-road, while resisting sag over time. The kit includes both upper thermoset coil isolators and lower front coil isolator/correction pads to help address coil bow and wear-prone factory pieces.
392 JL Wrangler, 2.5" True Dual Rate Coils, Front – compatible with Jeep Wrangler JL 392 (2018+)
These front MetalCloak True Dual Rate™ coils are built specifically for the JL 392 to provide a 2.5" lift with controlled ride quality and confident handling. The dual-rate concept gives you a usable balance: compliant movement when you need it and support when the Jeep is loaded or pushed harder.
Extra-long free length helps keep the coils seated in the buckets at full droop for reliable flex. The set also includes model-specific upper isolators and lower correction pads designed to replace problematic/worn factory pieces and reduce coil bow.
