Tamiya 15391 JR Stabilizer Head Set 11mm & 15mm - Track Stability Kit  [15391]

Stability tuning with Tamiya 15391 JR Stabilizer Head Set

The Tamiya 15391 JR Stabilizer Head Set is a practical upgrade for Mini 4WD builders who want to refine handling. The set provides two stabilizer head sizes, 11mm and 15mm, made from lightweight, low-friction POM plastic to resist wear while keeping performance consistent during race sessions.

Compatibility and how it works

These stabilizer heads work with both Mini 4WD and Mini 4WD PRO cars and accept rollers with diameters from 13mm to 19mm. The design pairs ball stabilizer caps with teethed washers to lock the head in place and reduce unwanted rotation at speed.

On-track benefits and setup

By lowering the car's effective incline, the stabilizer heads improve cornering stability and help maintain momentum through turns, especially on technical sections. Installation is straightforward: secure the head with a double screw shaft, toothed washer, and hex nuts, then test and fine-tune the height and roller choice for your track.
