{"product_id":"heavy-duty-race-rigid-6-pad-clutch-kit","title":"Heavy Duty Race Rigid 6 Pad Clutch Kit","description":"The ACT ZM4-HDR6 Heavy Duty Race Rigid 6 Pad Clutch Kit is engineered for high-performance applications, specifically for 6-speed transmissions. This kit includes ACT's popular Heavy Duty pressure plate, which features an exclusive diaphragm design that increases clamp load, reduces deflection, and maximizes clutch life. The diaphragms undergo a four-stage heat-treating process for enhanced performance.\n\nThe hub is made from heat-treated chrome-moly for superior strength and durability. This lightweight, rigid design contributes to quicker shifts and smooth operation. The engagement is noted as harsher compared to other discs, but it facilitates faster shifting. This disc is recommended for larger clutch sizes to better absorb heat.\n\nSpecifications for this clutch kit include a torque capacity of 359 ft-lbs, representing a 71% increase over OE. The clutch disc diameter is 8.8 inches (224mm) with a 1-inch input shaft diameter. The pressure plate type is Heavy Duty, and it comes with M8-1.25 x 20mm pressure plate bolts. The kit is covered by a 12-month warranty.\n\nWhile offering aggressive engagement and increased torque capacity, the rigid design may increase spline wear. Pedal effort is described as light to moderate, with aggressive engagement and a potential for increased gear rattle. The friction life is moderate, extended by ACT's diaphragm design. This kit is recommended for race use only.","brand":"ACT Heavy","offers":[{"title":"Default Title","offer_id":52686761165112,"sku":"ZM4-HDR6","price":574.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/661162901.webp?v=1784876424","url":"https:\/\/store.motormia.co\/products\/heavy-duty-race-rigid-6-pad-clutch-kit","provider":"MOTORMIA","version":"1.0","type":"link"}
