Take your Jeep Wrangler JL Unlimited EcoDiesel to the next level with the TeraFlex 4.5" Alpine CT4 Long Arm Suspension System. Engineered specifically for the added weight and torque characteristics of the 3.0L EcoDiesel platform, this premium long arm suspension system delivers exceptional off-road capability, improved ride quality, increased articulation, and maximum suspension performance on and off the trail.

The Alpine CT4 Long Arm System is designed for Jeep owners who demand superior adjustability, durability, flex, and handling in extreme off-road environments while maintaining comfortable highway drivability.
