Description:

  • The SB10-HDR4 kit features ACT's most popular Heavy Duty pressure plate.
  • ACT Heavy Duty pressure plates use an 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.
  • Precision cover stampings ensure rigidity and consistency.
  • ACT's 4-pad rigid race discs are made with high-quality ceramic friction materials. The chrome-moly hub is heat-treated for strength and durability.
  • The lightweight, rigid design allows for quicker shifts and smooth, trouble-free service.
  • With the 4-pad rigid race disc, engagement is harsher, but shifting is faster. The 4-pad rigid race disc is well-suited for smaller disc sizes in smaller engines.
  • Monoloc is included, providing uniform loading on the bearing and pressure plate to assure proper alignment, regardless of driver influence or vehicle modifications. Monoloc's hardened chrome-moly steel construction ensures years of service.

Top quality for the price but a little tight in the toe box
Size: 8.5, Color: Black Full Grain
A little tight around the toe box for me and I don’t have a particularly wide foot. But the quality is great and the look is awesome. Hoping they stretch out a bit with some wear!

Great quality and price, true to size, and comfortable fit
Size: 32W x 30L, Color: Medium Vintage
Nice jeans--very close in quality to my more expensive Wranglers. And they run true to size, which is a real bonus in today's unpredictable clothing markets. The flexibility of the material makes them very comfortable, whether you're walking or sitting. Good job, Amazon Essentials!
