Features

Over-Crank Protection

Over Crank protection on the Delco Remy 42MT starter protects the starter in adverse starting conditions, such as cold weather cranking, lower battery capacity, high-starting circuit resistance or operator misuse.

Semi Solid Link Solenoid

The semi-solid link solenoid on the Delco Remy 42MT minimizes joint relaxation and potential loss of connection integrity over the life of the starter.
 

Power Rating

The Delco Remy 42MT cranks up to 10 and a half percent faster than the competition.
