The Tamiya 92431 Double Aluminum Rollers are designed for Mini 4WD users who want a lighter rolling assembly to sharpen handling. Produced as part of the TKC 25th Anniversary black edition, the dual 13-12mm set is machined from lightweight aluminum to reduce rotating mass while keeping structural strength for track use.
Using these rollers can reduce wobble through chicanes and improve line stability at higher speeds. They are built to resist wear from repeated rail contact and can be used by hobbyists tuning their setup or by racers chasing consistent lap times. Verify mounting compatibility with your chassis to ensure correct spacing and alignment.
