The High-torque, gear-reduction design Buick 455 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 in both 153 & 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 Chevy Small Block and Big Block V8 Engines, as well as most V6 Engines.
