Description
A pair of precision-machined aluminum rollers, each combining a 13mm section and a 12mm section into a single stepped part. The larger 13mm section contacts the course fence on straights, while the smaller 12mm section takes over in corners, giving the car a more consistent contact profile through both.
Fitment covers the same broad nineteen-chassis range as most Grade-Up roller parts, from Type 3 through Super TZ-X, VS, MS, AR, MA, VZ, and ME. Aluminum rollers like these are noticeably heavier than Tamiya's plastic rollers, and racers commonly accept that extra mass in exchange for steadier momentum through corners and less vibration feeding back into the chassis at speed.
- Stepped roller diameter: 13mm / 12mm
- Material: aluminum
- 520 ball bearings and attachment hardware included
- Listed chassis compatibility: Type 3 through ME (19 chassis)
