Product Description: HD/Perf Street Sprung Clutch Kit

The HD/Perf Street Sprung Clutch Kit, identified as ZM12-HDSS, represents a blend of performance and streetability engineered by ACT. Weighing 26.8 pounds, this kit offers a torque capacity of 312 ft/lbs, exceeding OE standards by 46%. Featuring an organic disc material with a clutch disc diameter of 8.8 inches (224mm) and an input shaft diameter of 0.9375 inches, it is designed to deliver reliable performance on both the street and the track.

At its core lies ACT's popular Heavy Duty pressure plate, renowned for its exclusive diaphragm design, which increases clamp load, reduces deflection, and maximizes clutch life. Each diaphragm undergoes a meticulous four-stage heat-treating process, ensuring unparalleled performance. Precision cover stampings provide rigidity and consistency, essential for enduring performance under demanding conditions.

The kit incorporates ACT's Performance Street discs, featuring premium organic materials with high copper content for better heat transfer and steel-backed lining for greater burst strength and durability. These discs have reduced marcel for faster shift action to complement ACT pressure plates, ensuring increased strength and reliability.

Key Features:

  • Feel: Light to moderate pedal effort, smooth positive engagement, OE to mild gear rattle.
  • Life: Longer friction life, extended by ACT's exclusive diaphragm design.
  • Quality: Carefully engineered, precisely assembled, accurately balanced, with premium organic friction materials for heat tolerance and reduced fade.
  • Recommended Use: Suitable for both street and race use, offering a balance of performance and drivability.
  • ACT Difference: Rigorously tested, ensuring 100% clamp load and dynamically computer balanced for smooth operation even at high RPMs.

Inexpensive part and YouTube knowledge lead to quick fix
Size: 96158T-1PCS
Solenoid went out on boat. After viewing multiple videos on YouTube I figured that my solenoid was bad. Ordered this and received a day later. Replaced the other one and this worked perfectly.

Worked perfectly!
Size: 96158T-1PCS
Have an older Mercury 40hp 2 stroke. This Solenoid worked perfectly. It is not that easy to install, due to the design of the engine. It does require a bit of patient and the right tools to do it. If you have big hands and don't do this type of repair to often, call a friend that is better than you to get some help :) I have an older engine but it runs like charm. I will order an extra Solenoid and place in the box of "important spare parts" for the future. Very good experience for the purchase and overall quality of the part.

Perfect fit and works great
Size: 96158T-2PCS
Perfect fit and works great. It is great that it comes as a 2pk. I replaced both with no need to change wiring, and kept the working one I had, as backup.

It works as it should...
Size: 96158T-2PCS
Used it in a pinch for stater relay... it works great. Be aware... Mine required metric sockets for the nuts... 10mm for large terminals - 3/8 was too tight and same for smaller terminals 7mm fit better than 5/16 that was too loose. The mounting holes are also spaced closer together than the OEM on a mercruiser 260 in a mid 1980's boat but easy to remedy with a 1/4" drill bit.
