MetalCloak 7030 True Dual Rate – Front Coils for Jeep Wrangler JK (2007–2018)
The front end of a lifted JK has to do it all: stay predictable on-road, keep the tires planted off-road, and handle added weight from bumpers or a winch. MetalCloak True Dual Rate front coils are designed around that reality. The dual-rate layout helps the suspension move more freely for traction and comfort, while still providing stronger support as loads increase and the suspension compresses.
Key features
- Lift fitment: 3.5” front lift for JK 2-door or 2.5” front lift for JKU 4-door.
- Long free length to help maximize droop and front-end articulation.
- Stable in the buckets — designed to stay seated even at full droop.
- Controlled ride quality with better stability on-road and off-road.
- Consistent ride height with resistance to sagging over time.
- Upper front coil isolators included for a quieter, better-seated install.
