The High-torque, gear-reduction design GM LS Starter has a 12V, 2.2KW motor and a torque ratio of 15:1. 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. 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.

  • High-torque, gear-reduction design.
