Description

South Bend Clutch Stage 3 Endurance clutch kits are recommended for single mass flywheel (SMF) when original design is DMF (dual mass) to achieve optimal performance. These kits use the same race-engineered SFI-approved pressure plates as Stage 3 Daily Driver packages. The disc is designed for the special needs of a vehicle with circuit racing in mind. Kevlar® friction material is used for its unique friction compounds applied with high-energy levels. This translates to a perfect transition from one gear to the next. Discs are assembled with only performance components and equipped with torsion springs functioning as a damper between engine and gearbox. These Stage 3 Endurance clutch kits are recommended for applications such as rally, endurance race, club sport, autocross, performance street and daily driving. Order the kit you need.

Product Overview

*STAGE 4 EXTREME:* This is a "build to order" clutch kit intended for cars with HP modifications exceeding the stage 3 parameters. The Race Engineered pressure plate is modified for maximum plate load. The discs are puck design with sprung and un-sprung options. Friction material options include Sintered Iron and Graphite Impregnated Ceramic. Engagement characteristics can be abrupt. Hydraulic systems may need enhancing for proper clutch separation. Single mass steel SFI approved flywheels are required for safety. Torque ratings are calculated at time of ordering.
