Description: The MS1-HDG4 kit features ACT's renowned Heavy Duty pressure plate, designed for high-performance racing applications. ACT Heavy Duty pressure plates employ an exclusive diaphragm design to enhance clamp load, minimize deflection, and extend clutch lifespan. Each diaphragm undergoes a rigorous four-stage heat-treating process to ensure exceptional durability. Precision cover stampings maintain rigidity and consistency in ACT pressure plates. The 4-pad spring-centered race disc is engineered with a spring-center to effectively damp torsional vibrations, ensuring quieter operation and resilience under demanding conditions. ACT spring retainers feature wraparound spring windows and thicker stampings to bolster spring support, diminish stress concentrations, and enhance strength and reliability. Expect harsher engagement but quicker shifting with the 4-pad spring-centered race disc, making it ideal for smaller engines with smaller disc sizes.

  • 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, utilizes select ceramic friction materials for high heat tolerance and maximum performance

Perfect Pillow!
Size: Ultra Slim (2.75-Inch Height), Color: Blue
I have spent so much money trying to find the right pillow. As a side sleeper I would always wake up with a stiff neck but not with this pillow! It’s a perfect height and the pillow stays fairly cool. It’s totally my Goldilocks pillow!❤️

Great!
This SUPA MODERN Reading Pillow is absolutely what I have been searching for. I added a thick mattress topper to my twin bed and suddenly the wedge pillow I had was below the top of the mattress so I needed something else to put against the rails at the head. This reading pillow is almost exactly the same width as this standard twin. The pillow was shipped vacuum packed and looked so lumpy I was fearful it would never be comfortable but I followed the instructions and left it alone except for an occasional shake to fluff it for 72 hours. As often as I get stuff that’s vacuum packed I was still amazed by how this turned out. It’s very full and firm I’m sure some folks will like that you can remove some of the filler to soften it but I find it very comfortable as is. The shape does give it a little more lumbar support than similar pillows I have had in the past. The fabric cover is super soft but has yet to make me overheat. It does have pockets on the arms but they’re not very big I wouldn’t put much in there I was worried about falling. This is not the cheapest reading pillow but it’s far and away not the most expensive. As I was writing this review I saw that it has been marked down 20% PLUS there’s a 30% off coupon. That puts it down around the cheapest price point for a far superior pillow. Go get one NOW!!! I highly recommend this Reading Pillow!
