Note: 70-74 Z's REQUIRE the use of a 280Z Clutch Collar, part 21-2122 (see Related Items). 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.

Includes:

(1) 225mm Heavy Duty Pressure Plate
(1) Race Solid Disk
(1) Throw Out Bearing
(1) Pilot Bearing
(1) Pilot Tool

Description:
We recommend this ACT™ clutch for Drag Racing Z-Cars. The Race Solid Disk had increased torque capacity, faster shifts, and reduced inertia. It has very good durability, but shortened spline life. Race disks will have harsher engaging and some chatter.

Features:

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.
Carefully selected rivet design and materials for maximum strength. Solid center discs use 16 hub rivets for high torque and shock tolerance.
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.
