      Description

      High-Torque Starting Power. The Tuff Stuff Performance Gear Reduction Starter delivers powerful, reliable engine cranking performance for classic V8 applications. Built for vehicles with either 153 or 168-tooth flexplates/flywheels, this high-torque unit is engineered for consistent starts, even in high-compression setups. This product fits 1955–1986 Chevrolet Corvette C1, C2, C3, and C4 models, making it ideal for restoration or performance upgrades.

      Construction and Appearance. Featuring a combination of raw metal and matte black finishes, this starter offers a rugged look and long-lasting durability. It’s built in the USA using 100% new components—not remanufactured parts—for optimal reliability. The 9-tooth pinion gear engages smoothly with your flywheel, while the adjustable front block allows for better clearance around headers and oil pans in tight engine bays.

      Installation. This gear reduction starter installs as a direct replacement using the included bolts and shims for proper fitment and alignment. The adjustable design provides added flexibility, especially when working around modified or tight clearances. Installation is straightforward for experienced DIYers or professional technicians familiar with starter replacement and alignment procedures.

      Application. This Tuff Stuff Performance Gear Reduction Starter fits 1955–1986 Chevrolet Corvette C1, C2, C3, and C4 models. Designed for performance and longevity, it enhances starting reliability under demanding conditions and provides a modern solution for classic engines. Ideal for both daily drivers and high-performance builds, this starter is a valuable upgrade for consistent, high-power ignition.
