Powermaster 9439 Ultra Torque Starter for Chevy V8 with 139-Tooth Flywheel

The Powermaster 9439 Ultra Torque Starter is engineered for Chevy V8 applications using a 139-tooth, 10-pitch flywheel. Its 4.4:1 gear reduction delivers dependable cranking performance while helping reduce the load on the starter motor, making it a strong choice for street, performance, and competition-oriented builds. The natural-finish housing provides a clean, functional appearance that complements a wide range of engine compartments.
The straight-mount configuration supports direct installation on compatible Chevy V8 setups, while the compact design helps provide clearance in applications where space around the starter is limited. Designed as a complete starter assembly, the Powermaster Ultra Torque unit offers reliable engagement and consistent operation when properly matched to the vehicle’s flywheel, mounting pattern, and electrical system.
