OS Giken TY031-E000L Flywheel Bolt Set for Toyota Supra JZA80 2JZ-GTE

The OS Giken TY031-E000L is a high-performance flywheel bolt set designed specifically for the 1993-1998 Toyota Supra JZA80 chassis equipped with the 2JZ-GTE turbocharged engine and V160 6-speed transmission. This set includes 8 precision-engineered bolts required when installing OS Giken clutch systems.

OS Giken clutch systems convert dual mass flywheels to single mass designs for improved performance and engine response. During this conversion, material is removed from the flywheel to reduce weight, resulting in a thinner profile that requires shorter bolts than OEM specifications. These replacement bolts are engineered to meet the exact requirements of OS Giken's lightweight flywheel designs.

Key Features:

• Designed for OS Giken single mass flywheel applications
• Precision-engineered for proper torque specifications
• Required when installing OS Giken clutch systems (TS, GT, and R Series)
• High-strength construction for reliable performance under extreme stress

These bolts are essential hardware when installing any OS Giken clutch system on the Toyota Supra, as the lightened flywheel design requires shorter bolts than the OEM dual mass flywheel configuration. Always replace flywheel bolts when servicing components that experience continuous high pressure and rotational stress.
