Description:

BM13-HDG4 kit features ACT's most popular Heavy Duty pressure plate. ACT Heavy Duty pressure plates use exclusive diaphragm design to increase clamp load, reduce deflection, and maximize clutch life. All diaphragms endure a four-stage, heat-treating process for unparalleled performance. ACT pressure plates have precision cover stampings to provide rigidity and consistency. ACT's 4-pad spring-centered race disc 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. ACT's 4-pad spring-centered race disc is well-suited for smaller disc sizes in smaller engines.

Absolutely Essential for Any Athlete or Gym-Goer!
Size: Large, Color: (035) Steel / White / Black
I recently purchased the Under Armour Unisex-Adult Training Cotton No Show Socks 6 Pack, and I must say, they've become an indispensable part of my workout gear. Here's why these socks are a game-changer: Comfort Above All: These socks are incredibly comfortable. Made from a blend of cotton and synthetic fibers, they provide just the right amount of cushioning without feeling bulky. Whether I'm running, lifting weights, or doing yoga, my feet feel supported yet free. No Show, All Go: True to their name, these socks stay perfectly in place without slipping down into my shoes. This is crucial for maintaining a professional look at the gym or during sports activities. No more embarrassing sock peeks or having to constantly adjust them. Durability: For the price, these socks hold up remarkably well. I've washed them multiple times, and they haven't lost their shape or elasticity. They've survived the rigors of both my workouts and laundry day. Breathability: The material mix allows for excellent breathability. My feet stay dry and cool, reducing the chances of blisters or discomfort during long sessions. Pack Value: Getting six pairs in one go is fantastic. It means I always have a fresh pair ready, which is perfect for someone like me who works out frequently. Fit for All: These socks fit true to size and are designed to be unisex, making them a versatile choice for anyone looking to upgrade their sock game. If you're in the market for socks that combine comfort, performance, and style, look no further. Under Armour has nailed it with these no-show socks. They've quickly become a staple in my wardrobe, and I find myself reaching for them over any other sock I own. Highly recommended for anyone serious about their fitness routine or just wanting reliable, high-quality socks. 5 out of 5 stars - These socks are a must-have!
