Gear Reduction & Motor Plates

Thunderstruck offers several motor mounting and reduction drive options. Please contact us if you have custom requirements.

We build our own reduction drive assemblies to supplement our Sailboat Conversion Kits from stainless steel hardware - these assemblies include mounting plates and supports, reduction pulleys or sprockets, thrust bearings for prop shaft loads, and prop shaft couplers. 

We also offer access to the Torque Trends reduction drive assemblies, which are popular for custom high performance single speed EV conversions.
