Proform Parts 66273 - High-Torque 11:1 Compression 12V Starter for Chevy LS Engines - Will NOT work with Pontiac GTO

High-torque, gear-reduction design. 100% NEW, not rebuilt. 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). Approved by all leading sanctioning organizations.

* Not compatible with Pontiac GTO engine configuration
