C4 CORVETTE CONVERSION KITS
Upgrade Your C4 Corvette ZF 6-Speed with a RAM Push-Style Street Performance Clutch System
Stop fighting the factory pull clutch system and upgrade to a RAM Push conversion!
Model year 1989-1996 C4 Corvettes utilize a ZF 6 speed transmission with a factory pull style clutch system. RAM has engineered an all-inclusive clutch kit to replace this pull style unit with a conventional single or dual disc push style package including the pressure plate, clutch disc, billet steel flywheel and internal hydraulic release bearing. This package eliminates the factory fork and external slave cylinder.
Systems come with all of the lines and adapter fittings needed to connect right up to the factory master cylinder. A choice of 300 series organic or 900 series Powergrip HD metallic friction discs are available in single disc clutch kits, 300 series or 900 series in Concept 9.5 dual disc clutch kits.
NOTE: Installation of these systems requires proper measurement and setup of the RAM hydraulic bearing kit. We recommend reviewing the instruction sheet links prior to placing your order.
Installation requires flywheel bolt set 575.
