Tamiya 15404 JR 19mm Rollers for Mini 4WD - 5-Spoke Aluminium

The Tamiya 15404 JR 19mm Aluminium Ball Race Rollers add a lightweight, 5-spoke option to your Mini 4WD parts pile. Derived from the popular 19mm Aluminum Ball Race Rollers (Item 15160), these aluminium rollers are designed to keep mass low so the axle spins freely and your model stays composed through corners.

Built with ball bearings to minimise friction and fitted with rubber O-rings to soften impacts against track walls, these rollers suit both Mini 4WD PRO machines and classic Mini 4WD builds. They are a straightforward upgrade for pilots who want steadier cornering and predictable responses on different circuits.

Can these fit on older Mini 4WD chassis?

They are compatible with many older and current Mini 4WD frames, but check your axle spacing and mounting method to confirm fit before fitting them.

Do I need special tools to swap the rollers?

Basic hobby tools like a small screwdriver and pliers are usually enough; bearings are preinstalled but may need gentle seating on the shaft during installation.

What maintenance keeps them performing well?

Keep bearings clean and lightly lubricated, replace worn O-rings, and check for bent shafts after heavy impacts to preserve smooth operation.
