Product Overview
Description
Are you tired of breaking Sur-ron Drive Belts? Check out Warp 9’s Ultra Bee chain drive conversion kit.
Both the Motor and the jackshaft sprockets have Rubber Dampener rings Vulcanized to the sprockets.
This design makes the inner plates of the Chain contact the rubber outer rings before the chain’s rollers fully seat in the bottom of the sprocket.
The rubber rings also have a secondary effect of dampening the ringing effect of steel sprockets.
Ultra Drive Contents
Includes 2 dampened sprockets in EDM coated black steel.
Final drive ratio is the same as OEM belt drive.
Includes a KMC 520 O ring chain.
While louder than a belt drive, this kit is 10-12 decibels quieter than other aftermarket 520 chain drive kits on the market.
