Intro to the Tamiya 15429 JR High Speed EX Gear Set

The Tamiya 15429 JR High Speed EX Gear Set is a targeted upgrade for Mini 4WD MS chassis builds. By offering a 3.7:1 gear ratio, it supplies a middle-ground option for pilots aiming to tune both straight-line speed and corner control on mixed layouts.

MS chassis pairing and performance gains

Built for MS chassis compatibility, this gear set leverages the chassis modularity to make gearing swaps straightforward. The 3.7:1 ratio smooths power delivery and helps maintain traction through tighter sections without sacrificing too much top-end speed.

Practical racing uses and setup advice

Racers can use the 3.7:1 ratio when standard 4:1 or 3.5:1 choices prove too extreme. It is useful for balancing gear selection against motor type and tyre choice to get consistent lap times across changing track conditions.

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.

Excellent service, two of the items I purchased were out of stock but was given fair options on refund, store credit or replacement. I opted for replacement as there was a different version available and one of the items did arrive bent and they sent out

Do I need to change gear oil or grease with this set?

You should apply suitable light grease to gears for smooth operation. Avoid heavy lubricants that can increase drag and reduce efficiency.

Can I combine this with a higher torque motor?

Yes. Pairing with a torque-focused motor can improve starts and hill sections, but test to ensure the motor does not overload the gear train at sustained high RPM.

Will gear noise increase with 3.7:1?

Noise levels depend on mesh, lubrication, and shaft alignment. Proper setup and light grease will keep noise minimal while preserving efficiency.

Is this an upgrade for seasonal club events?

It is well suited to club events where track layouts vary. The extra tuning option helps adapt cars quickly between practice and race sessions.
