The Tamiya 95493 19mm Aluminum Rollers are a go-to upgrade for Mini 4WD racers who want better stability and predictable handling. These five-spoke rollers, fitted with green plastic rings, reduce contact wear and help keep the car tracking smoothly around curves.
These 19mm aluminum rollers are made to work with most Mini 4WD chassis layouts, offering an easy upgrade path. The plastic rings lower metal-on-plastic friction and protect both the roller edges and the track walls for longer service life.
Fitting these rollers helps maintain speed through bends by improving alignment and reducing derailments on tight sections. They are especially useful on technical layouts where consistent line holding matters more than outright top speed.
Installation is straightforward: basic hand tools and careful tightening are all you need. Check that the rollers spin freely and are secured to prevent loosening during a run.
