Tamiya 15251 19mm aluminium roller - plastic-ring tuning part for Mini 4WD  [15251]

Tamiya 15251 - 19mm aluminium roller with plastic ring

The Tamiya 15251 is a compact 19mm aluminium roller fitted with a resilient plastic ring, ideal for improving handling on the Mini 4WD circuit. This simple, durable part helps stabilise cars at speed and is useful for both newcomers assembling their first racer and experienced tuners refining setup.

Build fit and compatibility

Machined from quality aluminium for a strong but lightweight profile, these rollers use a plastic outer ring to cut friction and dampen noise. That combination gives smoother cornering and steadier line holding across a range of track surfaces. The rollers are compatible with many Tamiya Mini 4WD chassis types including MS and MA, and can be fitted without major modification.

On-track benefits for racers

Used to improve cornering control, the Tamiya 15251 rollers help keep speed through bends while reducing the chance of flipping or derailing. They offer a practical balance between grip and low resistance, helping drivers refine lap consistency without complex upgrades.
