Twin Motor Conversion Kit 60-9514: ProPulse’s Factory Dual-Motor Upgrade

October 23, 2026

Every ProPulse owner who has read the back of a T100 box has seen the line: Twin Motor Conversion Kit – 60-9514. It is the top of the factory option list, the upgrade that turned a single-motor starter car into a twin-motor machine. It is also, in our experience, the hardest ProPulse part to find new – which is why we photographed our blister-packed examples from every angle before listing them.

The kit fits both starter cars, the PRO-B100 buggy and the PRO-T100 truggy, and the packaging promise is pure mid-2000s: “Upgrade, Update and Outrun the Competition!” Ours are new old stock in the original blue-and-black blister: Twin Motor Conversion Kit 60-9514

On our own shelf, a B100 running the twin-motor setup with the rare aluminum conversion parts shows what the factory was aiming at – twin motors change the car’s whole character. If you are restoring a ProPulse and want it the way the box promised, this is the part that completes the build. More on the cars themselves in The ProPulse Story.
