Special performance set made to fit SFI flywheel 6375-15B. RAM clutch sets have a 5 year / 50,000 mile limited warranty (proof of flywheel resurfacing is required).
RAM HDX performance clutch kits are the top-level organic clutch combinations that RAM offers. In addition to the increased clamp load pressure plate, clutch discs feature a premium organic facing material utilizing either an 8 spring or helix center clutch hub assembly to maximize disc strength and durability. A lighter marcel spring in the disc carrier insures quick and clean shifting while minimizing chatter on takeoff. HDX clutch kits will give you the confidence, and are a great option for spirited driving and durability up to 450 horsepower. Use HDX clutch kits for mildly modified vehicles that will see very limited track time. For more severe duty use, please see our Powergrip and Powergrip HD clutch kits. HDX performance clutch kits include the higher clamp pressure plate, clutch disc, release bearing (where applicable), and alignment tool.
Features:
Increased clamp load pressure plate with comfortable pedal effort.
8 spring or Helix clutch disc hub and light marcel carrier.
Premium organic friction material.
Quick, clean shifting with minimal chatter on takeoff.
For applications up to 450 horsepower.
You must resurface your flywheel prior to the installation of any clutch and replace your pilot bearing (7600). Check flywheel for signs of heat spots, warping or cracks and replace any questionable ones. New flywheels, including SFI certified flywheels can be found in the engine section or by searching for flywheel. It is possible to install a 10.5 clutch in place of any 10 clutch as the Long style pressure plate mounting bolt pattern is the same. It is advisable to use thread locker on the pressure plate mounting bolts and torque to spec in the proper sequence.
See 7563-1AK, 7563-1BK for mounting hardware options.
