Description: The ZM8-HDG4 kit by ACT features their renowned Heavy Duty pressure plate. These pressure plates utilize an exclusive diaphragm design to enhance clamp load, diminish deflection, and maximize clutch life. Each diaphragm undergoes a four-stage heat-treating process for exceptional performance. Precision cover stampings ensure rigidity and consistency.

The 4-pad spring-centered race disc in this kit features 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. With the 4-pad spring-centered race disc, engagement is harsher, but shifting is faster. This disc type is well-suited for smaller disc sizes in smaller engines.

  • Feel: Light to moderate pedal effort, aggressive engagement, OE to mild gear rattle.
  • Life: Moderate friction life, extended by ACT's exclusive diaphragm design.
  • Quality: Carefully engineered, precisely assembled, accurately balanced, uses select ceramic friction materials for high heat tolerance and maximum performance.

Great Heel Socks
Material Type: Black - 3 Pairs, Size: Large
I don't know how they work but it's wonderful. I've had rough heel problems for a long time. I wear these everyday and my heels are not rough. They're not baby bottom smooth, but they are not ever going to be. These heel socks also oncce they are properly positioned snap onto the heel. Properly positioning them is easy when you put them on your foot with the heel cup in the correct orientation.

Too small
Material Type: Gray - 3 Pairs, Size: X-Large
Too tight! Even size large used for a man with smaller feet is too tight. Also, no instructions for use or care.

Good fit
Material Type: Black - 3 Pairs, Size: X-Large
My husband just started using these and they feel comfortable. Hasn't used them long enough to see if his heels are better. He has a high arch so I bought him the XL and they fit perfectly.

No more painful cracked heels! These really do work!
Material Type: Black - 3 Pairs, Size: X-Large
These really do work well. This is one of the first winters that I have not experienced painful, cracked heels. They are long lasting, and definitely make my heels smoother and softer after wearing them. For the first few times wearing them I simply went with the moisturizer embedded in them. After a few uses I then covered my heels with Aquaphor Advanced Therapy Healing Ointment. This worked even better, and I would recommend it. I am very glad I bought these. Of note, I have really big feet that are quite wide and the XL are a little snug but not uncomfortably so. I use them overnight, but also have worn them under socks and they work fine.

🧦 Simple & Effective – ZenToes Moisturizing Socks Review ✨
Color: Green Gingham & Multi Plaid, Size: Regular
These ZenToes moisturizing socks are such a smart and effective solution for dry, cracked heels! I really like that they only cover the heels instead of the whole foot—no hot, sweaty toes, which is a huge plus. They come in a pack of two, and for the price, it’s a great value. I also found that they fit well and stayed in place overnight. They were a bit snug around my foot, but still comfortable enough to wear. What really impressed me is how well they work. The socks are nice and thick, and after just one use overnight, my heels were noticeably smoother. Even better—the results lasted about a week without needing any extra lotion, which I personally love since I’m not a fan of applying creams. I would definitely buy these again and highly recommend them if you’re looking for an easy, low-maintenance way to keep your heels soft.
