Note: 70-74 Z's REQUIRE the use of a 280Z Clutch Collar, part 21-2122 below. If you have only your original 240Z or 260Z clutch collar, and not specifically an original collar from a 280Z, then this clutch WILL NOT WORK properly in your 70-74 Z.
Description:
We recommend this ACT™ clutch for Road Racing Z Cars. The Race Spring Disk has increased torque capacity, very good durability and good spline life, quiet operation, and reduced driveline shock. Race disks will have harsher engaging and some chatter.
- Drive plates are high carbon spring steel that is heat treated and black zinc plated to resist bending, cracking, fatigue and rust even under severe racing conditions.
- Thicker retainer stampings for increased strength and durability.
- Spring windows are heat treated to resist wear, increase strength and reduce the chance of springs “popping” out from hub wear.
- Hub forgings are CNC machined for precision and consistency.
- All friction pads are measured, sorted and matched before assembly to insure that each disc is uniform in thickness.
- Spring center race disc hub assemblies use bushings and cone springs similar to factory clutch discs. This creates frictional dampening which improves clutch life and reduces noise.
- Carefully selected rivet design and materials for maximum strength.
- Heavy duty torsional dampening springs are stronger than standard springs. No more warped inserts or loose ring gears.
- Premium ceramic friction materials provide high heat tolerance, high coefficient of friction and low wear rates. Our pads will hold approximately 28% more torque than standard organic materials.
- Spring retainers utilize a wrap around spring window that not only gives liberal support for the springs, but also reduces stress concentrations that are a common cause for failure.
- Splines are carefully broached to ensure exact fit onto transmission input shafts for long spline life and better clutch release.
- SFI certification is provided on all ACT race discs. ACT race discs are legal for competition in all racing organizations that require SFI certification.
- Precision stampings for disc components are manufactured using dedicated tooling. This allows ACT to offer the highest in quality and consistency.
