Patented Semi-Solid Link Solenoid - Standard on all new and reman 37MT, 41MT, 42MT, and 50MT.

Protects your truck from costly “stuck contact” situations caused by low battery voltage. Here's how it works: The link connects the plunger to the contact disc assembly. As the plunger moves to the “solenoid off” position, it disconnects the contact disc from the battery and motor terminals.

Competitive Solenoid Design
Relies on a 7.5 lb return spring to break contact with the disc and terminals
