Kyosho UMW708-12 1.2mm Rear Stabilizer Bar Red

This is the 1.2mm rear stabilizer bar for the Kyosho Ultima RB6 in mid-motor configuration. A stabilizer bar, also called an anti-roll or sway bar, links the left and right suspension arms so that when one side compresses in a corner the bar resists the chassis rolling over onto that side.

At 1.2mm this is the second softest bar in the four-bar UMW708 series, one step up from the 1.1mm. It is a useful middle setting: enough roll resistance to keep the buggy from feeling lazy on turn-in, but soft enough that the rear suspension still loads progressively and finds forward bite on a track that has started to dry out or break up through the day.

Go thinner for rough, loose or low-traction conditions where mechanical grip matters most; go thicker for high-bite clay and astroturf where you want faster direction changes. This is a service bar for the optional UMW708 rear stabilizer set, which must already be installed on the buggy. Fits the Ultima RB6 and RB6.6 in the mid-motor layout.
