LANCASTER, CALIFORNIA, January 12, 2023 — Advanced Clutch Technology (ACT) has released a range of clutch kits for the Jeep Wrangler JL & Gladiator JT Applications (see spec sheet for detailed application listings).
ACT solves the factory clutch and flywheel troubles on the 2018+ Jeep Wrangler/Gladiator (JL/JT) by replacing the expensive OE DualMass Flywheel/Twin Disc Clutch and lackluster performance with a powerful 11-inch Single-Disc clutch and flywheel. ACT’s new Clutch Kit improves torque capacity, reliability, and, best of all, clutch feel. This kit is designed to work with factory hydraulics for easy installation, and ACT offers two flywheel weights and two friction materials to best suit your needs.
ACT’s new Clutch Kits for the Jeep JL & Gladiator include a Heavy Duty Pressure Plate, Street Mass Flywheel (JP5 Kits) or Pro-Mass Flywheel (JP6 Kits), a choice of Disc, Release Bearing, Bolts, and Alignment Tool. The specially designed diaphragm spring of ACT’s Heavy Duty Pressure Plate dramatically increases clamping force and incorporates hardened diaphragm fingers for longer clutch life.
The JP5 Kits feature the Street-Mass Flywheel, developed with no significant change of inertia, making it well-suited for normal street use. The JP6 Kits feature the Pro-Mass Flywheel, developed with greater inertia to reduce stalling, improve pulling and crawling capabilities. It is perfect for heavy vehicles or oversize tires. The proper mass distribution gives an optimal increase of inertia with a minimal weight penalty. ACT Flywheels can be resurfaced with no need to purchase additional parts.
The ACT Street Clutch Kit pro
ACT’s new Clutch Kits for the Jeep Wrangler include a Heavy Duty Pressure Plate, a choice of Disc, Release Bearing, Pilot Bearing, and Alignment Tool. ACT’s Heavy Duty Pressure Plate will increase torque capacity, durability and clutch life by providing 21% more clamping force, increased surface area, exclusive ductile iron casting, and hardened diaphragm fingers for decreased wear.
The ACT Performance Street Clutch Kit combines the Heavy Duty Pressure Plate with a Performance Organic Street Disc for smooth engagement and predictable performance even in the harshest environments. The ACT Street Disc features premium steel-backed organic friction materials and 8% additional surface area using the stock flywheel or 16% more with the ACT Flywheel. Added surface area means added clutch life and heat capacity.
The Street Clutch Kit provides a moderate and consistent pedal feel, smooth engagement, high burst strength and significantly improved durability. This kit will hold 479 FT-LB of torque at the flywheel.
The ACT Race Clutch Kit combines the Heavy Duty Pressure Plate with a cerametallic 6 pad spring-centered Xtreme Race Disc. This disc is highly durable while allowing for quick shifting but engages aggressively. The Xtreme 6 Pad Disc is for high-powered engines and recommended for track use only. The ACT Race Clutch will hold 613 FT-LB of torque at the flywheel.
Many aftermarket clutches in the Jeep Market are using gray iron castings, placing the driver and others at a higher risk
The 44lb Pro-Mass Flywheel boasts a 28% increase of inertia reducing the chance of stalling or rapid RPM loss, making drivability easier over tough obstacles and terrain. For versatility, ACT’s new Flywheel is a direct replacement to the OEM Flywheel and can be used with the OEM 11” Clutch but offers the benefit of 16% more clutch surface area when combined with the ACT Clutch. A second bolt pattern is also drilled for use with the earlier 10.5” JK Clutch if desired.
For the assurance of safety, each ACT Flywheel is certified to meet SFI Specification 1.1 standards, making them legal for competition where SFI 1.1 certification is required or recommended.
