Ultra Torque Starter GM LS Engine

The POWERMASTER Ultra Torque Starter for GM LS-Series engines delivers reliable high-torque cranking performance for engines equipped with 168-tooth flywheels. Engineered specifically for LS engine platforms, this starter combines a 4.4:1 gear reduction ratio with robust construction to provide dependable starting across demanding conditions. Whether rebuilding a classic muscle car, modern swap, or high-performance street engine, this unit offers the cranking power and durability required for serious LS builds.

The 4.4:1 gear reduction ratio is calibrated to optimize torque multiplication without sacrificing engagement speed, a critical balance for LS engines that demand quick, aggressive starts under load. The 168-tooth flywheel compatibility ensures proper mesh engagement and synchronized cranking velocity. At 11.35 lbs with compact dimensions (7.5 × 5.7 × 12.7 inches), this starter integrates into tight engine bays common on LS conversions and modern LS platforms without requiring extensive fabrication or mounting modifications. The natural finish resists corrosion and blends cleanly into engine compartments where appearance and longevity matter equally.

This starter is purpose-built for LS engine enthusiasts, fabricators, and engine builders who require OEM-quality starting performance on carbureted or fuel-injected platforms. It handles both naturally aspirated and supercharged LS combinations, delivering consistent cranking torque across a range of compression ratios and displacement configurations. Buyers upgrading from worn original starters, completing LS swaps into older vehicles, or building competition engines will find this unit delivers the reliability and performance expected from POWERMASTER's lineup of high-output electrical components.
