Koswork Rear Stabilizer Bars 1.0–1.4mm (Optima Series)

Fine-tune rear roll stiffness and handling balance with the Koswork Rear Stabilizer Bar for the Optima Series. Under part number KOS04305RBAR, it is offered in 1.0, 1.1, 1.3 and 1.4 mm sizes to help you match your RC setup to different tracks and grip levels.

Why It Helps

A rear anti-roll (sway) bar links the left and right suspension to reduce chassis roll, improving consistency through corners. Choosing a thinner or thicker wire lets you adjust rotation, rear grip and mid-corner stability to suit your driving style.
