Chevy V8 Ultra Protorque Starter 153/168 Tooth

The Chevy V8 Ultra Protorque Starter 153/168 Tooth from CVR Performance is engineered for high-performance engine builds and demanding street or race applications where reliable cold-start and sustained cranking power are non-negotiable. This starter delivers the torque and dependability required by serious Chevy V8 enthusiasts upgrading from worn OEM units or building modified engines that demand superior starting performance. Whether you're running a naturally aspirated stroker, a boosted small-block, or a classic big-block platform, this unit bridges the gap between stock capability and professional-grade reliability.

Built with a robust 4.4:1 gear reduction system, the Chevy V8 Ultra Protorque Starter generates exceptional cranking torque while maintaining efficient power draw—critical when dealing with compression ratios above 10:1 or high-displacement engines that resist turning over. The 153/168 tooth configuration accommodates both standard and oversized flywheels, offering flexibility for custom builds where flywheel selection varies. The five-position mounting block enables fitment across multiple Chevy V8 generations and engine bay configurations, while the straight-mount design simplifies installation and ensures solid mechanical support without complex brackets or adapter plates.

This starter is ideal for engine builders, hot rodders, and performance shops installing custom Chevy V8 powerplants in street rods, drag cars, or restomod projects where factory starters fall short. The aggressive gear reduction and dual-tooth flywheel compatibility eliminate weak-point starting issues common in heavily modified engines. Installation is straightforward for mechanics with basic V8 experience—the five-position block allows fine-tuning alignment to your specific engine block and bellhousing, ensuring repeatable engagement and long service life. Weighing 11.81 lbs and engineered for permanent installation, this starter delivers years of reliable service across diverse Chevy V8 platforms.
