ACT Heavy Duty pressure plates provide increased torque capacity, durability, and extended clutch life. What makes ACT pressure plates the highest standard in the industry? First manufacturing always begins with new units. These are not rebuilt from worn out parts. Second, pressure is increased the right way. Altering the geometry alone is not enough. Instead, a stronger diaphragm is engineered. ACT diaphragms are heat treated using an exclusive 3 stage process and the release bearing contact area is hardened to reduce wear. Third, the pressure and release travel of the unit is designed to be in the optimum working range. Finally, by using proven assembly procedures consistency and precision is assured. Every unit ACT produces is accurately balanced and tested. No guesswork, no hype, only proven engineering and calculated results.

*Note: Taken directly from ACT's Website, please follow these directions if you are having problems with disengagement:
TB 105-3: Improve Disengagement for the following vehicles:Turbo Eclipse/Talon/Laser and Galant VR4
First refer to TB 105-1. Then if you still need to improve disengagement, here are some common areas to examine.
For First Generation 89-94-1st- Examine the pedal assembly. It has been found the lever arm connection to the pedal cross shaft wears down and decreases the distance the push rod travels in to the clutch master cylinder. Replace the lever arm or pedal assembly as needed. 2nd- Examine the T.O. bearing for proper lubrication on the guide tube and clutch pivot ball. And 3rd- The rubber hydraulic line can be replaced with a steel braided line for better action.
For Second Generation 95-99 1st- These cars have an accumulator cylinder that operates between the clutch master cylinder and the slave cylinder which is designed to reduce feedback to the driver and therefore increase travel requirements. Consider bypassing this device to decrease the travel requirements and give the driver more feedback. 2nd- Due to a manufacturers defect, the crankshaft design tends to prematurely wear the thrust bearing on some engines. It is commonly referred to as crank walk. This doesn't happen to all vehicles but is frequent enough to be mentioned. 3rd- Examine the T.O. bearing for proper lubrication on the guide tube and clutch pivot ball. And 4th- The rubber hydraulic line can be replaced with a steel braided line for better action.
