Track Tuned 17mm Aluminum Rollers - Tamiya 95563

These Tamiya 95563 HG Lightweight 17mm Aluminum Ball-Race Rollers are precision machined to lower rotational mass on your Mini 4WD. Constructed from light aluminum, the ringless rollers are drilled with eight holes to keep weight down to 0.81 grams per roller, roughly 0.25 grams lighter per roller than many stock types, which helps reduce drag and improve acceleration out of corners.

Integrated 520 ball bearings provide smooth, dependable rotation that stabilises handling and helps deliver repeatable laps. The rollers work with both Mini 4WD and Mini 4WD PRO chassis, though some vehicles may need slight body or mounting clearance tweaks.
