    High Torque Starter
  • Chevy LS
  • 1.4KW 12V Motor
  • 11:1 Maximum Recommended Compression Ratio

    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).
  • Not Compatible with 2004-2006 Pontiac GTO engine configuration

Small Size, Big Power! This 100% new mini-starter is the hot ticket for applications where tight header clearance tends to make your starter hot. And since it's only 2/3 the size of a stock starter, it will fit where a stocker won't. Choose from standard 1.4 kilovolt or hi-output 2.0 kilovolt model, with no increase in size.
