ZM1-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.This Part Fits:

A great and strong book stand!
Size: 4-Tier (10.43"x14.17"x45.67")
This book stand is great and strong. Each shelf holds up to 5 kg and it is quite easy to put together and in the video I show exactly how to do it. And there are some hooks that you hang in the sides of the stand if you want to hang anything there! You make sure to see the measurements because they are right, and for me was just right!

Pay attention to instructions
Size: 4-Tier (10.43"x14.17"x45.67")
You definitely need to pay attention to the instructions when building because it’s very easy to build this incorrectly. The numbers on the instructions are small so please pay attention. Other than that the bookshelf is sturdy, lightweight, and holds so many books.
