Rear MetalCloak True Dual Rate™ coils for the Jeep Wrangler JL 2-door (2018+) designed for a 2.5" lift. They deliver stable ride height, better on-road control, and a wide range of travel off-road thanks to their long free length.
MetalCloak JL Wrangler 2-Door 2.5" True Dual Rate™ Coils – Rear (2018+)
These True Dual Rate™ rear coils are engineered specifically for the Jeep Wrangler JL 2-door and a 2.5" lift. The goal is predictable handling on the street and a real improvement in suspension performance off-road.
Built from a high-strength chrome silicon steel alloy, the coils are designed to hold their height over time. The long free length helps keep the spring seated at full droop, while the dual-rate design balances comfort with support under load.
