The HD/Perf Street Sprung clutch kit, designated ZM2-HDSS, is engineered to provide excellent performance and durability for street and occasional race use. With a weight of 12.5 lbs and a torque capacity of 245 ft/lbs (36% over OE), this kit offers a balance of strength and usability.

Featuring ACT's most popular Heavy Duty pressure plate, this kit utilizes an exclusive diaphragm design to increase clamp load, minimize deflection, and extend clutch life. The pressure plate undergoes a four-stage heat-treating process for unmatched performance and reliability. Precision cover stampings ensure rigidity and consistency, enhancing clutch operation.

The clutch disc, constructed from organic materials, boasts a diameter of 8.8 inches (224 millimeters). These premium organic materials with high copper content offer better heat transfer, reducing fade, and increasing durability. The steel-backed lining provides greater burst strength and reliability. Reduced marcel allows for faster shift action, complementing the ACT pressure plate while maintaining strength and reliability.

With a light to moderate pedal effort and smooth positive engagement, accompanied by OE to mild gear rattle, this clutch kit provides a comfortable yet responsive driving experience suitable for both daily driving and occasional track use.

ACT's meticulous engineering ensures precise assembly and balance, with 100% clamp load testing and dynamic computer balancing for smooth high RPM reliability. Backed by a 12-month warranty, this kit reflects ACT's commitment to quality and performance.

Reliable and dependable
Style: 17548N
I installed a new starter on my 1995 Dodge Ram Cummins, and it has exceeded my expectations. Ive had it for about 20k miles now. Installation was straightforward, and the starter fit perfectly without any modifications. From the first turn of the key, it cranked the engine smoothly and reliably at a great price. Since installing it, my truck starts every time, even in cold mornings, which has been a huge relief. The starter feels durable and well-built, giving me confidence that it will last for years of regular use. It’s clear that this is a quality part designed for heavy-duty performance, just what you need on a classic Cummins diesel. Overall, I’m extremely satisfied with this starter. If you’re looking for a reliable, strong, and easy-to-install replacement for your Dodge Ram Cummins, this one is an excellent choice.

Good quality except for the supplied bolts.
Style: 18493N
So far starter works great. Be careful if you use the supplied bolts. They are not good quality. The last thing you want to do is snap them off in the block. The starter itself really spins the engine over. If it lives long, it's a great deal for the money.
