Bolt - 11mm x 1.5 x 23.5 LS Flywheel/Flexplate

The Bolt – 11mm x 1.5 x 23.5 LS Flywheel/Flexplate is a genuine Chevrolet Performance fastener engineered for LS-series engine builds and rebuilds. As a critical component in the crankshaft-to-transmission interface, this bolt secures the flywheel or flexplate assembly with precision tolerances and OEM-grade specifications. Whether you're assembling a street engine, race platform, or transmission swap, selecting the correct fastener specification prevents catastrophic drivetrain failure and ensures reliable power delivery from your LS platform.

Manufactured to Chevrolet Performance standards, this 11mm x 1.5 pitch fastener features the exact thread geometry and tensile strength required for LS flywheel/flexplate applications. The 23.5mm length ensures proper engagement without bottoming or creating excessive protrusion that could interfere with starter or torque converter clearance. With a compact design weighing 0.06 lbs per fastener, it integrates seamlessly into tight engine bay configurations while maintaining the structural integrity needed to handle sustained horsepower and torque loads. OEM-specification bolts prevent galling, thread stripping, and premature wear that often results from using generic fasteners in high-stress drivetrain assemblies.

LS platform enthusiasts, engine builders, and transmission specialists rely on this fastener during manual or automatic flywheel/flexplate installation. It is essential for Gen III, Gen IV, and Gen V LS engine configurations and compatible with both street and competition builds. When performing any crankshaft-to-transmission assembly work, always replace fasteners in sets using the correct torque specification to guarantee even clamping force and eliminate the risk of flywheel or flexplate runout. Genuine Chevrolet Performance components ensure compatibility with factory specifications and long-term durability.
