XRAY 303838 X4 Under Arm 1.8MM Rear Anti-Roll Bar  [XR-303838]

Low profile 1.8MM rear anti-roll bar for sharper X4 handling

The XRAY 303838 - X4 Anti-Roll Bar UAM is aimed at hobbyists seeking better rear stability without raising ride height. Mounted beneath the suspension arms, the bar helps lower the center of mass for improved mid-corner balance.

Bearings for smooth, repeatable movement

External ball-bearing mounts on the bulkheads prevent binding and allow you to make quick changes with predictable results. This arrangement is useful when testing different roll rates between heats.

Easy to read and adjust

Laser-etched stripes indicate the bar size so you can pick the correct piece at a glance, and the height adjustment screw provides simple tuning of roll transfer to suit grip levels and driving style.
