ZR1 Clutch Assembly For 2005-2010 LS Corvettes
Flywheel, Twin-Disc Clutch Accepts Stock 2009-2010 C6 ZR1 Twin Disc Pressure Plate Assembly
For those Corvette owners looking to add even more torque-holding capacity to their vehicles, Lingenfelter Performance Engineering (LPE) has designed a flywheel and clutch assembly kit that allows for the installation of a Corvette ZR1 clutch on LS2, LS3 and other LS-based engines.
The Lingenfelter 6-bolt flange flywheel is an OEM spec steel design created specifically to accept the production 2009 General Motors ZR1 Corvette dual disk clutch pressure plate assembly. This allows the ZR1 clutch to be installed on LS2, LS3 and other LS-based engines that use the more common 6-bolt crank flange. Lingenfelter's new clutch system is designed to provide excellent street drivability and good clutch pedal feel, while still offering exceptional power and torque holding capacity.
The Lingenfelter ZR1 flywheel and clutch kit includes all of the major components required for installation in a C6 Corvette, and fits in the 2005-2010 C6 Corvette (LS2, LS3 and LS7 equipped vehicles). However, due to the larger diameter of the LS9 clutch, it does not fit in 1997-2004 C5 Corvette bell housings.
Lingenfelter Performance Engineering's 6-bolt flywheel weighs 19.1 lbs. and, when combined with the pressure plate and disk assembly, has a total weight of 57.4 lbs. While the package is roughly equivalent to the production Z06 clutch and flywheel assembly weight of 56.9 lbs., it is 6.7 lbs. lighter than the production ZR1 clutch and flywheel assembly.
A 9-bolt version of the Lingenfelter steel LS9 flywheel (p/n L360040309 at $824.95) is also available as a direct replacement flywheel for the ZR1 Corvette. Replacing the factory LS9 cast iron flywheel with the LPE steel flywheel saves 6.7 lbs. of rotating mass on the ZR1 Corvette.
In addition, Lingenfelter has engineered a slave/actuator cylinder spacer (p/n L360031410 at $98.95) that allows installation of the flywheel and clutch assembly in the 2010 Chevy Camaro SS bell housing.
The 6 bolt steel flywheel is available as an individual item (p/n L360010105 for $824.95) or in kit form (p/n L360020105 for $1,499.95). The kit form includes:
Lingenfelter steel flywheel
GM pressure plate and disk assembly
GM clutch slave cylinder (aka actuator or releaser)
The Lingenfelter Performance Engineering LS9 Flywheel and Twin Disc Clutch Assembly can be purchased direct from Lingenfelter.
