Introducing the Tamiya 15355 JR PRO Gear Set

The Tamiya 15355 JR PRO High Speed Gear Set offers a 4:1 gear ratio for Mini 4WD MS chassis racers wanting crisper acceleration. It is tailored for layouts where maintaining momentum through corners and short straights matters most.

Compatibility and What to Expect on Track

Built specifically for the Mini 4WD PRO MS chassis, this gear set is not universal. Drivers switching from the stock 3.5:1 ratio will notice quicker punch out of corners. Best results come when used with a high-speed motor like the REV-Tuned.

Contents and Practical Advice

The set includes two G19 (blue) counter gears and two G20 (orange) spur gears, ideal for replacing worn parts or trying alternate setups. It is a cost-effective upgrade to experiment with acceleration characteristics without investing in a different car.

I have been purchasing Tamiya products with Rcjaz for a couple of months now, selection is awesome and service is quick and reliable, considering I leave half way around the world.

Will this affect top speed?

The 4:1 ratio shifts focus toward acceleration rather than absolute top speed, so expect quicker starts and stronger mid-corner drive but a different top-end feel than lower ratios.

How hard is it to swap the gears?

Swapping gears is straightforward for anyone comfortable with Mini 4WD maintenance. Ensure correct mesh and check bearings or bushings while you are in the gearbox.

Are upgrades needed after fitting these gears?

You may want to experiment with motor and tyre combinations to balance acceleration and handling after installing the new gears.
