The High-torque, gear-reduction design GM LS Starter has a 12V, 1.4KW motor and a torque ratio of 11:1. This PROFORM Starter is 100% NEW, not rebuilt with remanufactured parts! Offset design results in more clearance between the oil pan and the starter, and can be rotated for additional chassis clearance. Fits 168 Tooth Flywheels. The high-torque, high-output motor spins the engine over faster than stock starters, delivering 40-50% more cranking power. 3.75-to-1 sealed gear-reduction drive and full ball bearing construction. Includes shims to set pinion-gear engagement (when necessary). Fits GM LS 1, 2, 6 and 7 Engines.
