About the Tamiya 13mm Aluminium Ball-Race Rollers

The Tamiya 15437 13mm Aluminium Ball-Race Rollers are designed to lift the handling of Mini 4WD cars. Made from low-weight aluminium, they keep strength up and overall mass down. Each roller incorporates 520 ball bearings to provide steady, low-resistance rotation along track guides.

Where these rollers work best

Ringless by design, these rollers are flexible for front or rear mounting on a variety of Mini 4WD chassis. They help sustain speed through chicanes and corners by keeping the car tracking smoothly.

Performance gains on race day

Reduced friction from the ball bearings leads to crisper cornering and the potential for faster lap times on demanding circuits. The robust bearing setup supports reliable operation session after session.
