ACT HDR4 - Heavy Duty with 4 Puck Disc Clutch Kits ACT ACT HDR4 - Heavy Duty with 4 Puck Disc Clutch Kits


This kit utilizes a Heavy Duty Pressure Plate, which is superior to the stock pressure plate.

The clutch disk itself is made of a copper ceramic material which holds approximately 28% more torque than an organic lining. ACT Copper Ceramic Xtreme Race Discs engage fairly harsh and are not normally recommended for street use. ACT recommends 6-pad ACT Xtreme Race Discs for larger sizes to absorb more heat and for smoother engagement. The 4-pad ACT Xtreme Race Discs engage harsher, shift faster, and are well suited for smaller disc sizes from smaller engines. All clutch kits include throwout bearing and alignment tool (if applicable).

Comments: All available in ductile iron for additional charge
