Product Description: HD/Perf Street Sprung Clutch Kit

The HD/Perf Street Sprung Clutch Kit, designated as Z66-HDSS, is meticulously engineered by ACT to deliver exceptional performance in both street and race applications. Weighing 13.8 pounds, this kit boasts a torque capacity of 275 ft/lbs, surpassing OE standards by 46%. It features an organic clutch disc material with an 8.8-inch (224mm) diameter and an input shaft diameter of 0.9375 inches.

At its heart lies ACT's most popular Heavy Duty pressure plate, renowned for its exclusive diaphragm design that enhances clamp load, minimizes deflection, and maximizes clutch life. Each diaphragm undergoes a rigorous four-stage heat-treating process, ensuring unparalleled performance even under the most demanding conditions. Precision cover stampings provide rigidity and consistency for reliable operation.

Paired with the pressure plate is ACT's Performance Street disc, featuring premium organic materials with a high copper content for superior heat transfer and a steel-backed lining for enhanced burst strength and durability. These discs boast reduced marcel for quicker shift action, complementing the ACT pressure plates with increased strength and reliability.

Key Features:

Big Guy Approved – No More Chair Drama
Finally found a big and tall office chair that doesn’t quit on me. The 600lbs support feels rock solid, and that wide spring cushion? Like sitting on a couch at my desk. I use it for work, gaming, even late-night scrolling—still comfy. Smooth wheels, adjustable arms, ergonomic back… it just works. If you’re tired of chairs tapping out early, this one’s built different.

Worth every penny.
This chair is exactly what I need for working from home. Its spacious seat and high weight capacity make it incredibly comfortable and reliable. The ergonomic design provides excellent back support, preventing fatigue even after long periods of sitting. The adjustable armrests are convenient and add extra comfort. The PU leather material gives it a premium feel while maintaining practicality for everyday use. I am very satisfied with this purchase and will definitely buy from them again.

Great sturdy chair!
Color: Dark Black
The chair is very comfortable for long term sitting. I’d say the best part is that the arms also move around for those of us with bigger thighs. Totally worth the buy!

Misinformation!
Color: Dark Black, Color: Dark Black
Be aware that this does NOT ship with a class 4 gas lift. The whole reason I bought this chair was because it shows in the advertising this comes with a class 4 lift. Have contacted the seller and gotten the "we have a 1 year warranty" line. I am in the 300+ lb weight class. I have had many MANY other class 3 lifts and I know it will work as intended for about 2.5 years, and then it will slowly fail and not be able to stay up.
