The ACT XACT ProMass Flywheel combines advanced engineering and high-quality materials to deliver outstanding performance and longevity. Key features include:

• Greater inertia for improved climbing, pulling, and overall drivability
• Optimized mass distribution for maximum inertia with minimal weight penalty
• Single-piece construction eliminates issues common with dual-mass flywheels such as warped inserts and loose ring gears
• Heat-treated forging enhances strength and toughness under demanding conditions
• Induction-hardened ring gears for extended durability and long service life
• Resurfacing capability without the need for additional parts, reducing maintenance costs
• Forged, CNC machined, and dynamically computer balanced for smooth operation and reliability
• Reduced driveline slop and no gear rattle for a more precise and responsive feel
• Recommended for both street and off-road use, including rock crawling and towing
• Backed by a one-year warranty, reflecting ACT’s commitment to quality and customer satisfaction

Construction & Design:

The ProMass flywheel is crafted from high-grade forged steel, providing exceptional strength and resistance to wear. Its one-piece construction acts as an efficient heat sink, helping to dissipate heat generated by the clutch during operation and reducing the risk of failure. The induction-hardened ring gear is engineered to withstand the rigors of heavy use, ensuring longevity even in demanding off-road environments.

Precision CNC machining and dynamic balancing guarantee smoothness and reliability, minimizing vibrations and enhancing clutch engagement. This robust design eliminates the common issues found in dual-mass flywheels, such as looseness and gear rattle, delivering a more consistent and durable performance.

Installation & Fitment:

The ACT XACT ProMass Flywheel is a direct fit replacement for a wide range of Jeep Wrangler models from 2007 through 2018, including Rubicon, Sahara, Sport, and Unlimited variants, as well as select Jeep Grand Cherokee models from 2005 to 2010. Installation requires no modifications, making it a straightforward upgrade for experienced mechanics and enthusiasts alike.

Its compatibility with factory clutch components and the ability to resurface the flywheel without additional parts simplify maintenance and extend service intervals. This flywheel is designed to integrate seamlessly with your vehicle’s drivetrain, ensuring reliable performance and ease of installation.
