1968-1988 RAM single disc clutch kits and dual disc systems for Chevrolet Corvette

Replacing the clutch system in your 1968-1988 Corvette?  Whether you are restoring a classic to factory specification or building a street/competition car, RAM can tailor a system to meet your needs.  Stock replacement single disc clutch kits are available to provide a smooth engagement and light pedal for that concours restoration or for upgraded power levels to give a nice balance between driveability and holding power.  For higher horsepower applications, choose from one of the RAM Street Dual disc clutch systems that allow you to have your cake and eat it too – a smooth engagement that holds up to bog power and use!

 

RAM HDX Clutch kits

Unless you are doing a stock restoration, you probably can benefit from having a mildly upgraded clutch system like the RAM HDX clutch kits.  HDX Clutch kits give you a higher clampload pressure plate without too much pedal effort, and an upgraded organic disc that allows for smooth engagement, yet will stand up to spirited driving on the street.  For more holding power in dual purpose street and track cars, check out the RAM Powergrip series clutch kits.
