The following tech data should answer most questions regarding our gear reduction starters . We supply starters for most popular British sports cars. 

 General Information: 

Solenoid Design - The inherent design of the Lucas solenoid is very susceptible to “Hot Start Syndrome.” This is because the windings of the solenoid are encapsulated in steel. There is simply no means for the heat to dissipate. The solenoid for our Hi-Torque starter is encased in aluminum. Inside the area for the solenoid there is the equivalent of 1/2 cup volume of air. Further, it is equipped with a vent hole. Every time the solenoid is engaged, it pushes (pulls) cooler air into the solenoid area thus virtually eliminating the “Hot Start Syndrome.” 

Gear Ratio - The gear ratio of the starter is 4.44:1 which enables the starter to develop its unique torque values. 

Bearings vs Bushings - The Hi-Torque starter is equipped with five (5) full roller bearings while the typical Lucas unit uses two (2) bushings to suspend the armature.
