TA1-XTG6 kit features ACT's powerful Xtreme pressure plate and spring center 4 pad race disc delivering ultra-high torque capacity, aggressive engagement, quiet operation and increased toughness to withstand the demands of off-road racing. ACT?s exclusive diaphragm design dramatically increases clamp load, reduces deflection and maximizes clutch life. All diaphragms endure a four-stage heat-treating process for unparalleled performance. ACT precision pressure plate cover stampings provide rigidity and consistency while precision machined pressure plate castings absorb heat. ACT?s spring center 4 pad race discs boast quality parts throughout, with robust spring center sections to absorb driveline shock and premium ceramic friction materials to hold power even under the most abusive conditions.
