XRAY 303846 X4 Rear Above-Arm Anti-Roll Bar 1.6mm  [XR-303846]

Above-arm rear stabiliser for X4 chassis

The XRAY 303846 rear anti-roll bar is an RC-scale component engineered for the X4 family rear end, compatible with X4 and X4F rear suspension arms. This 1.6mm bar is tuned specifically to suit X4F rear geometry.

It fits using a ball-bearing roll bar system so the bar rotates on bearings for smooth, low-friction operation. The bearing-mounted arrangement simplifies bar swaps and gives precise, repeatable feedback during setup sessions.

Height and engagement are adjusted with a single screw interface that lets you change roll bar height quickly without disassembling the rear suspension. Laser-engraved stripes on the bar identify thickness at a glance, helping you match setups between practice runs.

Use this above-arm mount anti-roll bar when you need a compact method to change rear roll stiffness and fine-tune handling balance on X4-series RC touring or competition chassis.
