BMW N52 3.0L Dual Mass Flywheel

Optimize your BMW's performance with the BMW N52 3.0L Dual Mass Flywheel. This dual mass flywheel is engineered to meet the highest standards of quality and reliability, ensuring smooth and efficient power transmission for your BMW.

• Genuine BMW part guarantees compatibility and performance
• Designed specifically for BMW N52 3.0L engines
• Reduces engine vibrations for smoother operation
• Improves clutch engagement and drivability
• Durable construction for long-lasting durability

This is an OEM LuK stock twin mass flywheel for the N52 non-turbo engine in the 128i, 325i/328i/330i, 525i/528i/530i, and Z4 30i. It's manufactured by OEM supplier LuK. Sachs recommends a new dual mass flywheel (DMF) on every other clutch replacement. There are several indicators for replacing the flywheel: damage to the clutch contact plate (from a severely worn clutch disc), grease leaking from inside (overheating), build-up of clutch material on the contact plate (excessive slipping and overheating), and failure of the internal damping system.

The dampening system uses rubber or coil springs to absorb driveline vibrations. Through age, excessive heat, and aggressive use the rubber loses its resilience and the metal springs lose their strength and become brittle. If the clutch and flywheel have become overheated the internal grease may break down as well. A DMF failure can be massive and catastrophic, not to mention dangerous as bits of metal and rubber fling themselves through the transmission bellhousing. Heat and aggressive driving will accelerate the wear so race and track cars should have their stock flywheels replaced at regular intervals or with any new clutch. Even normal street cars should plan for a new flywheel if it has high mileage.

Polyurethane Transmission Mount Set - Street Performance

Your transmission mounts are the backbone of your drivetrain. Stock rubber mounts often degrade quickly, leading to excess movement, mis-shifts, and, in some cases, even chassis damage. ECS Tuning’s Street Performance Polyurethane Transmission Mount Set offers an upgraded solution built for street and track performance alike.

Constructed from high-quality polyurethane and 304 stainless steel, these mounts are crafted to withstand the demands of high-torque and forced-induction setups, minimizing deflection and giving you more direct power delivery. With a 70A durometer rating, these mounts offer the best of both worlds—stiff enough to handle aggressive driving but still comfortable for daily commutes. For track-focused builds, we also offer a stiffer 80A version (sold separately).

Key Features:

Improved Stability: Reduced transmission movement for fewer mis-shifts and over-revs Polyurethane Construction: Stronger than rubber, with excellent oil and water resistance Engaging Driving Experience: A more connected feel without excessive vibration Dual Options: Choose Street (70A) or Race (80A) to match your driving style Durable Design: Mechanical interlock feature for high-stress applications Pair your new clutch and flywheel kit with these premium mounts for an unparalleled driving experience. Plus, our DIY guide makes installation easy—ECS Tuning has you covered from start to finish!
