JHM B6-B7 S4 CHROME-MOLY FORGED SINGLE-MASS LIGHTWEIGHT FLYWHEELS AVAILABLE NOW!!
NOTE: This is now an option you can choose instead of our traditional Alumimum Flywheels. Use dropdowns above to choose.
The Chrome-Molly Forging allows fewer opportunities for failure and promotes uniform, efficient heat transfer from the clutch disc. This is to prevent warped friction inserts or loose ring gears. It is strategically lightened, stronger, safer and has better thermal capacity than OE cast flywheels. With smooth operation at all RPMs, these flywheels meet the needs of both the enthusiast and the hardcore racer.
Features:
• Chatter Free
• Easier engagement from a stop compared to aluminum
• Improved Engagement and momentum when Launching
• One-piece Chromium Molybdenum forging is stronger and more durable than billet steel, aluminum or cast iron.
• Tough, precision-made and dynamically balance
• Lighter and stronger than stock flywheels
• Integral ring gear is induction-hardened for maximum gear life
• Material is properly distributed for strength, greatest heat dissipation and reduced inertia
• CAD-designed, CNC-machined and computer balanced for quality and precision
• Improved throttle response and acceleration
• Smooth operation at all RPM’s
• Optimal mass distribution
• Lead-in chamfers
• Heat treated and tempered
• SFI Spec. 1.1 Certified Design
Flywheel Weight:
OEM: 26lbs
JHM: 15lbs
JHM Flywheel is 11lbs Lighter!
Included:
1x JHM Chrome-Moly Forged Lightweight Flywheel
1x OEM Pilot Bearing (Pressed Into Flywheel)
8x OEM Flywheel Bolts
NOTE: This flywheel will not work properly on a B6 S4 without the appropriate pressure plate like in the JHM B6/B7 S4 Clutch/Lightweight Flywheel Combo
NOTE: JH Motorsports has seen many B6 S4 flywheels fall apart in some cases causing major damage to the transmission. This is why JHM built all its clutch and flywheel products around the new and updated B7 style flywheel and pressure plate. This way we can update all B6 owners to B7 spec components. Our complete kits fit ALL B6/B7 S4 4.2l V8s, we basically take the guesswork out of updating your B6 to B7 specs.
In typical JHM style here are 2 videos of some of the abuse we have put this clutch and flywheel combo through during our R&D process with our in house 2005 B6 S4.

INSTALLATION AND TORQUE NOTES HERE
NOTE: Clutch break in is important and must be done properly. For the Stage 3 clutches you need to drive as much city type driving as you can for the first 500 miles (each time you start from a stop or shift it aids in break in, Highway mileage does not count). For Stage 4 clutches the procedure is the same but you must do this break in procedure for 750 miles. Due to Kevlar’s resistance to wear it takes longer to break in. You also MUST avoid any racing activities, launching or aggressive driving that gets the clutch hot during this period.
NOTE: For those that are looking for a more robust, race oriented clutch setup we highly recommend looking into our R-Series line-up that does not have an SAC. The SAC in OEM and other aftermarket pressure plates work great for comfort and OEM-like drive-ability, however it is not designed to take excessive abuse of track days or aggressive street driving. We have done rigorous testing since 2012 to develop the ultimate clutch solution for both street and track and the R-Series is what is needed to take these cars to the next level.
