Track Ready Tamiya 15449 JR 17mm Aluminum Rollers with Plastic Rings - Pair  [15449]

Summary of the Tamiya 15449 roller set

The Tamiya 15449 JR 17mm Aluminum Rollers with Plastic Rings are aimed at Mini 4WD builders wanting cleaner handling through bends. The aluminium roller core combined with a plastic outer ring reduces contact drag and supports more consistent lap times.

Features and model compatibility

• Material: Aluminium roller body with a plastic outer ring
• Design: 3-spoke layout to encourage steady rotation
• Compatibility: Compatible with Mini 4WD and Mini 4WD PRO chassis

Effect on handling

These rollers lower friction where the roller touches rails, helping the car carry speed through corners. The ball bearings assist in smooth spin, which reduces speed loss on twisty circuits.

Fitting guidance

The Tamiya 15449 kit includes screws and nuts for straightforward installation. Fit to the chassis, then verify alignment and torque after a short shake-in run to ensure reliable performance.
