Tamiya 94934 JR 17mm Roller Set for Mini 4WD Tuning

The Tamiya 94934 JR 17mm Aluminium Rollers combine a stiff aluminium core with smooth plastic ring sleeves to reduce drag when negotiating corners. The included ball bearings are preinstalled to give uniform spin and reduce start-up resistance.

These rollers suit both Mini 4WD and Mini 4WD PRO platforms, so they fit a wide range of builds from stock racers to tuned hobby chassis. Use them to refine handling at race meetings or casual track sessions.

Are spacer shims needed for some chassis types?

On some modified frames you may need thin shims to align the rollers correctly. Check lateral clearance and axle play before final tightening.

Do the plastic rings wear quickly under track use?

Plastic rings are designed for low friction but will show gradual wear over time. Inspect them after frequent runs and replace when grooves or flat spots appear.

What lubricant should I use on the bearings?

A light, fast-penetrating bearing oil keeps rotation smooth without attracting dust. Avoid thick greases that increase drag.

Will these rollers change lap times noticeably?

On technical tracks with many turns you may see improved corner exit speed, which can reduce lap times. Results depend on chassis setup and tyre choice.
