Consistent Drive with RACEOPT Rear Belt

The RACEOPT 3m-189-(PU) Optional Rear Belt (RO-S3M-189) is aimed at racers and club drivers who want a reliable replacement for 1/10 scale cars. The polyurethane make gives it resistance to wear while maintaining smooth power flow.

Broad Chassis Compatibility

This rear belt is compatible with many popular kits from manufacturers like Xray, Spec R, Yokomo, TOP, 3Racing, and RGT. Its versatility makes it useful when running different setups at the track.

Practical Maintenance and Fit

Installing the RACEOPT belt is quick with basic tools, so you can get back on track. The PU construction helps minimise belt stretch and cuts down on slippage under load.

Will this belt work on modified chassis with different pulley sizes?

It can, provided the belt length and tooth profile match your pulley setup. Measure existing belt length and tooth pitch before swapping.

What maintenance keeps the RO-S3M-189 performing well?

Keep pulleys clean and check for debris after each run. Periodic tension checks will prevent premature wear and maintain performance.

Is the RACEOPT 3m-189-(PU) suitable for high torque setups?

The PU belt is durable, but for very high torque applications review pulley ratios and torque loads to avoid overstressing the belt.

How do I check belt alignment quickly?

Rotate the drivetrain slowly by hand and watch pulley engagement. Misalignment shows as uneven seating or lateral movement on the pulley flanges.
