It is compatible with numerous V8 engine configurations, including LS1, LS2, LS3, LS6, LSX, and various Gen V LT1, LT4, L83, and L86 engines. This tool easily fits both manual and automatic RWD bellhousings but is not suitable for front-wheel drive (FWD) engines.

Construction

Constructed from heavy-duty 1/4-inch cold-rolled steel and featuring TIG welding for enhanced strength, the flywheel locking tool ensures reliable performance under demanding conditions.

Installation and Usage

Installation is straightforward; simply remove the starter, position the tool over the starter mounting area, and secure it with the supplied grade 8.8 bolts. The tool engages with the flywheel or flexplate ring gear teeth to prevent the crankshaft from rotating, providing a secure hold while you remove or tighten the harmonic balancer bolt or service the flywheel and flexplate.

Compatibility

This locking tool can be used on engine stands or in vehicles that have compatible engines installed. Each package contains one Chelhead LS flywheel locking tool along with two properly sized grade 8.8 mounting bolts.
