The Discovery 4-wheel drive motor kit upgrades an electric golf cart to be 4×4 capable by adding two direct-drive electric motors mounted inside the front wheels. The kit comes ready to install and includes two AC electric motors, two motor controllers, a Golf Car Module (GCM), a controller box, a 4WD switch, wiring harnesses, power cables, adapter brackets, additional hardware, and a smartphone app.

• On-the-fly 4×4. A dash switch engages 4 Low or 4 High in both forward and reverse. Use 4 Low for maximum torque, then move to 4 High for higher speeds. You do not have to stop the cart to change modes. In the Off position, the cart operates as a normal 2WD golf car.
• Towing and climbing power. SilverWolf designed the system to add torque for towing utility and recreational trailers and for climbing hills in forward and reverse. We will talk with you about what is appropriate for your cart.
• Front anti-lock and regenerative braking. The kit adds front-wheel anti-lock braking, plus regenerative braking that SilverWolf says can help increase electric range.
• Enclosed and waterproof motors. SilverWolf describes the motor system as fully enclosed and waterproof. They advise parking in a dry area after wet use and not leaving the motors sitting submerged in water.
• SilverWolf app. Monitor vehicle speed, battery levels, power, and more from your phone.

Per SilverWolf, 4 High provides torque up to 12 mph and 4 Low provides maximum torque up to 9 mph. The motors freewheel after those speeds. A lift and wheels at least 12 inches in diameter are required. This kit is for electric carts, not gas carts.

The Teekon 9kW / 12 HP AC motor kit upgrades an electric golf cart’s stock DC rear motor to an AC permanent-magnet motor. SilverWolf says this change is designed to deliver greater range, greater torque, and increased top speed.

• More range. SilverWolf says the Teekon kit can deliver 20% greater range than the stock DC motor on a standard golf car, with regenerative braking and power management built in.
• Greater torque sooner. SilverWolf describes full-torque capability from the start, which helps with hills, uneven ground, and towing.
• Driving profiles in the app. Built-in profiles include Turtle mode for low speed, Long Range mode, Standard mode, Standard LSV (SilverWolf lists speeds up to 25 mph), and Sport Mode (SilverWolf lists speeds up to 32 mph, and a waiver is required to activate it). Street-legal limits and local laws still apply.
• Anti-theft lock. The phone app can remotely lock the golf car.
• Works with Discovery 4WD. The kit includes a 400 A solenoid and a Golf Car Module (GCM) that SilverWolf says allows seamless integration with the Discovery 4WD system.
