Product Description: HD/Race Sprung 4 Pad Clutch Kit

The HD/Race Sprung 4 Pad Clutch Kit, designated as Z66-HDG4, is engineered by ACT to provide exceptional performance in high horsepower street or race applications. Weighing 13.7 pounds, this kit boasts a torque capacity of 355 ft/lbs, exceeding OE standards by 87%. It features a ceramic clutch disc material with an 8.8-inch (224mm) diameter and an input shaft diameter of 0.9375 inches.

At its core, this kit features ACT's renowned Heavy Duty pressure plate, utilizing an exclusive diaphragm design to increase clamp load, reduce deflection, and maximize clutch life. Each diaphragm undergoes a meticulous four-stage heat-treating process for unmatched performance. Precision cover stampings ensure rigidity and consistency for reliable operation.

Paired with the pressure plate is ACT's 4-pad spring-centered race disc, featuring a spring center to properly damp torsional vibrations for quieter operation and resist failure even under harsh conditions. ACT spring retainers utilize wraparound spring windows and thicker retainer stampings to provide spring support, reduce stress concentrations, and increase strength and reliability. The 4-pad spring-centered race disc delivers harsher engagement but faster shifting, making it ideal for smaller disc sizes in smaller engines.

Key Features:

  • Feel: Light to moderate pedal effort, aggressive engagement, with OE to mild gear rattle.
  • Life: Moderate friction life, extended by ACT's exclusive diaphragm design.
  • Quality: Carefully engineered, precisely assembled, accurately balanced, using select ceramic friction materials for high heat tolerance and maximum performance.
  • Recommended Use: Specifically designed for high horsepower street or race use, catering to performance enthusiasts seeking uncompromising performance.
  • ACT Difference: Rigorously tested, ensuring 100% clamp load and dynamically computer balanced for smooth operation even at high RPMs.

Vehicle Fitment: This clutch kit is compatible with a wide range of vehicles, including various Mazda and Ford models from the 1993 to 2003 model years. Compatible vehicles include:

  • 1993-2003 Ford Probe Base, SE
  • 1993-2003 Mazda 626 DX, LX
  • 1993-2003 Mazda MX-6 Base
  • 2001-2003 Mazda Protege DX, ES, LX, Mazdaspeed
  • 2002 Mazda Protege5 Base

Asurion "Assures" nothing!
Asurion has terrible Customer Support. All machine based. They give you no phone # for human interaction. Their online Support process is very close-ended. It is a checklist designed to frustrate purchasers whose issue lies outside only the very issue. My issue: I bought "Cuisinart TOB-40FR Custom Classic Toaster Oven Broiler, Silver (Renewed)" on May 26, 2024. It stated it had a 90 day warranty. So I bought an Asurion Protection Plan also to cover it for 3 years. The toaster started flaking off metal finish inside the oven over the cooking area. I tried to file a claim with Asurion and they told me the Manufacturers warranty was still in effect and I should contact Cuisinart. This despite the oven was sold with a Amazon Renewed verbiage stating a 90 day warranty. And they have nothing on their "Machine Checklist" to cover this eventuality. And I would assume I am not the only one who takes the "Renewed" route and backs it up with a "Protection Plan". They will frustrate you no end. I suspect, like many insurances, they seek to deny, deny, deny, in hopes the purchaser will give up.

GIFT CARD AS REPLACEMENT, NO CHOICE OF CHECK OR REPLACEMENT. GOOD COMPANY
PROS: * A decent company, responsive and fair. * Allows you to buy items from anywhere you want, and buy the warranty at Amazon. * Provides better coverage than other warranties, and covers more, including breakage! CON: They don't send you a check in order to buy wherever you want, send a replacement, or give you a choice. Instead, they send you an Amazon Gift Card. That's OK if you're a big Amazon shopper, but sometimes, you can get a better price elsewhere.
