JB Racing Aluminum Lightweight Flywheel – E39 540 6/’96-’03

Give your E39 540 a serious performance edge with JB Racing’s Aluminum Lightweight Flywheel. Replacing the heavy factory flywheel, this upgrade dramatically reduces rotating mass, allowing your engine to rev faster. The result? Crisp shifts and seamless rev-matching that transform your driving experience.

Perfect for spirited street driving, this flywheel reduces both weight and Moment of Inertia (MOI), requiring less energy to spin and freeing up more power to hit the pavement.

Each flywheel is CNC-machined from high-strength billet aluminum and built as a single-mass unit. It replicates all the critical OEM dimensions and is fully compatible with original clutch components.* Every JB Racing flywheel is proudly designed, built, and balanced in-house using cutting-edge equipment trusted by pro race teams across the country.

Features Include:

  • Precision CNC machining and zero-balancing to eliminate vibrations

  • Replaceable, bolted-on hardened steel clutch surface (no rivets)

  • Durable heli-coil inserts to protect pressure plate threads during service

  • OEM-style starter ring gear

  • Gall plate made from hardened steel to prevent bolt damage

  • Includes flywheel bolts, pressure plate bolts, and 10mm captive dowel pins

  • All hardware is metric

  • Weighs only 13 lbs—down from the OEM’s hefty 38 lbs
