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

Rear anti-roll bar for X4 series

The XRAY 303846 rear anti-roll bar is an RC-scale component designed for the X4 family rear end, intended to work with X4 and X4F rear suspension arms. The bar comes in a 1.6mm thickness version tuned specifically for the X4F rear geometry.

Mounting is via a ball-bearing roll bar system so the roll bar turns on bearings for smooth, low-friction movement. The bearing-mounted design simplifies swapping bars and makes incremental adjustments feel precise and repeatable during setup sessions.

Height and engagement are adjustable 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 across practice runs.

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