The ACT XACT Flywheel Pro-Mass delivers improved drivability, durability, and performance for Jeep Wrangler JK models from 2012–2018. Built from heat-treated forged material, this flywheel is engineered to increase inertia without unnecessary weight, providing smoother power delivery and enhanced climbing capability on challenging terrain. Its optimized mass distribution improves momentum over obstacles and reduces driveline slop, resulting in more responsive handling and less gear rattle compared to traditional dual-mass flywheels.
The one-piece forged construction offers exceptional strength and efficient heat transfer, reducing the risk of warping or clutch failure during demanding conditions. Induction-hardened ring gears extend component life, while CNC machining and dynamic balancing ensure smooth operation across all RPM ranges. Designed for both on-road and off-road environments, the ACT XACT Flywheel is fully serviceable and can be resurfaced without additional parts, making it a long-term, low-maintenance upgrade for drivers seeking dependable performance.
