Does anyone have any information on act cw05 counterweight ??? I ran across it a while back while looking for a counterweight. Only info I have on it is that it fits rx7 and rx8 but also says that it fits mustang 5.0 which has to be wrong since the counterweight on the mustang is built into the crankshaft itself . Only reason I'm even interested in it is because it's a fraction of the price of a OEM counterweight and if balancing the RA why not ACT make reliable products. Anyone using this part number???

 

CW05 is for the Ford Mustang only. CW05 // Advanced Clutch Technology

FC & FD rear counterweights on the bottom of this page ACT Flywheel (86-91 RX-7)

 

CW01 is for 86-88
CW02 is for 89-95

ACT is just rebadged OEM, which you may still be able to get through local mazda dealers and other various outlets.

 

Thanks for clearing that up. Different vendors had it listed for different applications. So I wasn't sure exactly what it was. I didn't even know the 5.0 had a separate counterweight . (I don't touch piston engines).
