Dual Mass Flywheel & Bolt Kit
This complete kit includes a precision-engineered dual mass flywheel along with the correct replacement flywheel bolts.
Designed to match OEM specifications, it provides smooth power delivery,
reduced drivetrain vibration, and secure installation. Replacing both the
flywheel and bolts together ensures reliable performance and prevents future
driveline issues.

What the Products Do
- Dual
Mass Flywheel: Absorbs torsional vibrations between the
engine and transmission, allowing smoother gear changes, reduced noise,
and longer clutch life.
- Flywheel Bolts: Provide the correct clamping force to securely mount the flywheel, ensuring proper alignment and long-term safety.
Together, they ensure seamless power transfer, smoother driving, and protection of transmission components.
Symptoms of a Failing Flywheel
- Vibrations felt through the clutch pedal or cabin
- Rattling or knocking noises at idle or during gear changes
- Difficulty engaging gears or jerky clutch operation
- Burning smell from the clutch area
- Slipping clutch or reduced performance under load
Common Reasons for Failure
- Wear
& Tear: Friction surfaces and internal springs in the dual mass
flywheel degrade over time.
- Heat
Damage: Overheating from aggressive driving or slipping clutches can
warp or crack the flywheel.
- Improper
Bolt Torque: Reusing old bolts or incorrect installation can lead to
loosening or misalignment.
- High Mileage Stress: Daily stop-start driving and torque load eventually wear down damping springs.
Why Replace as a Kit?
- Ensures a secure installation with new bolts designed for one-time use.
- Restores smooth drivetrain operation and reduces vibrations.
- Prevents clutch and gearbox damage caused by a worn or loose flywheel.
- Saves labour costs compared to replacing parts separately.
- Provides long-term reliability and peace of mind.
Ideal For: Clutch replacement jobs, resolving vibration/noise issues, or preventative maintenance on high-mileage vehicles.

Speedi Sleeves to Repair Worn, Grooved Seal Surfaces
Over time, sealing surfaces will become grooved, making a good seal impossible.The most economical and fastest method of shaft repair is to install the CR Speedi Sleeve. Speedi Sleeve is a precision engineered piece of stainless steel. It's ultra-thin wall design allows it to be used without changing the sel size ans its finish is perfect for lip sealing applications. Speedi Sleeve is built with removable installation flange. The installation tool included in every box allows the seal to be put in. This avoids the possibility of distortion from heat or other installation methods
