Action Clutch's Stage 4 (1MD) Clutch Kit is designed to withstand even the most challenging conditions. Featuring a heavy-duty single diaphragm pressure plate, reinforced drive straps, and an Unsprung MIBA Ceramic (available in a 4 or 6 puck) disc, this kit provides peak performance and extreme durability for low/mild horsepower vehicles. Our Unsprung MIBA Ceramic clutch kit provides quicker engagement and will introduce some clutch chatter, which will minimize after proper break-in. For those looking to take their dedicated race vehicles to the next level, the Stage 4 (1MD) Action Clutch Kit provides maximum control and power with little compromise on reliability. At Action Clutch, every kit is quality checked by one of our experienced engineers (with over 60 years of collective experience) and signed off as safe before being released as a finished product. This gives you peace of mind knowing that your Action Clutch will perform consistently every time. NOTE: Purchasing the wrong type of clutch kit for your specific engine power output can result in premature clutch failure, damage to the transmission and void warranty eligibility. If you're unsure what kit is right for you, contact Action Clutch direct. 170% INCREASED HOLDING CAPACITY OVER FACTORY KIT RACE APPLICATIONS / DRAG / ROAD / DRIFT RACING
