Product Details: The Delco Remy 31MT™ 12V 10-Tooth Starter Motor ensures you are Ready for the Road Ahead™, with its development from the popular 29MT™ design, having 10% more peak power than the competition. The new, 31MT™ starter replacement covers virtually all Class 6 and 7 commercial truck vehicles in the aftermarket. This gear reduction starter features positive shift engagement for a smooth engine start. In the case of tooth abutment, the armature rotation in full power clears the abutment to allow pinion engagement. The benefit is zero click-no-crank (CNC), allowing these medium duty starters to be the power choice for vehicles that experience numerous starts and stops. FleetPride is your First Click in Heavy Duty®.
