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

Perfect!
Scent: White Peach, Size: 14oz
Everything you would want in a pet hygiene product. Pet hair type I used this on: low shed, dense cork screw (tight curl) hair/fur. Excellent lather, even application, clean and easy rinsing. The scent is lovely and gentle, perfect for my human senses and -more importantly- the animal minded fragrance notes are happily accepted by my pet’s delicate olfactory system. I start spa bath time by offering an open cap sniff of the products. This is one we both prefer. My pet hasn’t run from the room or attempted to flee the wash basin 🙂

A Gentle Clean That Leaves My Pups Smelling Incredible
Scent: White Peach, Size: 14oz
Mrs. Meyer's Clean Day 3-in-1 Dog Shampoo in White Peach is a breath of fresh air compared to the harsh, chemical-heavy formulas often found on pet store shelves. The 3-in-1 claim—cleansing, softening, and freshening—actually holds up; the formula lathers well enough to cut through dirt and grime but rinses out quickly without leaving any sticky residue. Because it is made with essential oils and plant-derived ingredients, it feels very gentle on the skin, which is a huge plus if your pets are prone to itching or dryness after bath time. The standout feature, however, is the scent. The White Peach aroma is light, fruity, and natural, avoiding that overpowering "wet dog covered in cheap perfume" smell that other brands tend to produce. It strikes a perfect balance: strong enough to neutralize odors but subtle enough that it doesn't seem to bother the dogs' sensitive noses. It makes the entire bathroom smell like a summer orchard rather than a grooming station. Most importantly, the lasting freshness is unbeatable. After using this, my dogs smell absolutely amazing—clean, sweet, and huggable—for days, not just hours. It completely eliminates that lingering "doggy odor" and leaves their coats feeling soft and fluffy. If you are looking for a shampoo that makes you actually want to bury your face in your dog's fur, this is the one to buy.

Works as advertised
Scent: White Peach, Size: 8oz
Exactly as described. My dog seems to enjoy the spraying and wiping process - no struggles. I am not fond of the aroma, even though I usually love anything peach. The smell lasts several days on the dog, so we're not smelling the "dog" smell as much.

Mrs Meyer's works well for stinky pets.
Scent: White Peach, Size: 14oz
This is the best shampoo I've tried to get rid of stinky dog odor and I've tried many! Another shampoos when you wash the dog the smell would return the next day. But with this one the smell lasts for days, ridding her body odor & leaving her coat soft fluffy and the peach smell is pleasant enough to cuddle.
