The Tamiya 94801 JR 5mm Pipe set is a compact upgrade for Mini 4WD builds that rely on double aluminium rollers. These precision pipes help maintain correct roller spacing and reduce wobble during fast sections of a track.
These 5mm pipes are designed to pair with Tamiya double aluminium roller assemblies, keeping the roller shafts square to the chassis. The pack of four gives you enough pieces to refresh multiple roller positions or carry as spares for race day.
Correct roller alignment from these pipes helps cut inconsistent drag and supports predictable cornering lines. That makes your lap times more repeatable, especially through technical sections where stability matters.
