ACT XACT Flywheel ProMass for Select 2009-2016 BMW 135i, 335i, 435i, 535i, and Z4 - 601030
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits select 2009-2016 BMW 135i, 335i, 335is, 435i, 535i, and Z4 sDrive35i models.
The ACT XACT Flywheel ProMass (MPN: 601030) is engineered to significantly improve engine response and acceleration by reducing rotational mass compared to the factory dual-mass unit. Designed for both high-performance street use and competitive racing, this flywheel features a one-piece construction that eliminates the common failure points of multi-piece designs, such as warped inserts or loose ring gears.
- Manufactured from heat-treated forgings for maximum strength and toughness.
- Induction-hardened ring gears provide long-term durability and reliable starter engagement.
- CNC machined and dynamically computer-balanced for smooth operation at high RPM.
- Uniform one-piece design ensures efficient heat transfer from the clutch disc to prevent overheating.
- Technical note: Provides a performance-oriented feel with OE to mild gear rattle.
