The factory BMW S65 dual-mass flywheel is engineered with comfort in mind, catering to the luxury-oriented expectations of the brand’s driving experience. Its design focuses on dampening drivetrain vibrations, smoothing out gear transitions, and minimizing harshness during operation. However, this refinement costs valuable performance. The dual-mass flywheel adds a substantial 27 lbs of rotational mass to the drivetrain, which significantly hinders throttle response and makes rev-matching feel sluggish and disconnected. Moreover, dual-mass flywheels are notorious for being a weak link in modified or high-performance builds and can prove costly to replace when they inevitably fail.
Our Single-Mass Lightweight Flywheel Conversion addresses all of these shortcomings with a purpose-built, lightweight, single-mass design that prioritizes performance. Weighing in at only 19 lbs., this design significantly reduces rotational mass, allowing your S65 to achieve its true motorsport potential!
Features & Benefits:
Precision machined from 4140 HT heat-treated chromoly steel for exceptional toughness, even wear properties, and increased durability.
Material quality promotes even wear across the entire friction surface, prolonging component lifespan.
Heat treated to HRC 28-32, tempered to relieve stress and improve dimensional stability.
Hardness improves component wear characteristics.
Black oxide coated for corrosion resistance on non-friction surfaces.
Precision balanced to exceed OEM specification (G16 spec to 175g-mm).
Specifically designed to work with S65 OE-architecture clutches.
Optimized step height maximizes clutch clamp load and offers a prolonged service life.
Performance:
8 lbs. lighter than the factory BMW flywheel!
OEM Dual-Mass: 27 lbs.
Turner Motorsport Single-Mass: 19 lbs.

Ensure precise clutch installation with this specialized alignment tool, designed specifically for N54-equipped BMWs. While most aftermarket clutch kits include a generic alignment tool, many are intended for the N55, which is incompatible with the N54 due to differences in pilot bearing mounting and flywheel design.
This tool is engineered for both 6-bolt (01/2009+) and 8-bolt (-01/2009) N54 flywheels, allowing you to accurately center and align the clutch disc on the flywheel during pressure plate installation. Achieve a hassle-free and precise fit with this essential service tool.
