Team Xray adds 1.6mm and 1.8mm rear anti-roll bars for X4/X4F with ball-bearing mount

# What was released Team Xray introduced two new rear anti-roll bars sized 1.6mm and 1.8mm that are designed for use with the ball-bearing roll bar mounting system on the X4 and X4F rear suspension arms. The announcement came as a Team Xray press release carried by LiveRC.

# Why this matters These parts focus on tightening up rear roll control while making on-car adjustments faster and more precise. The ball-bearing mount reduces friction where the roll bar rotates, which makes the bar respond more freely and simplifies swapping bars during practice or at the track.

# How the system works

• The roll bar rotates in ball bearings to minimize binding and provide consistent movement.
• Height is adjustable by a screw, allowing small setup changes without removing the assembly.
• Laser-engraved stripes on the bar correspond to thickness for quick visual identification.

# Practical use and setup guidance

Use the height-adjust screw to fine-tune the effective leverage and roll response on-track. The ball-bearing rotation helps the bar follow suspension movement more freely, which can produce more consistent transient behavior when the car is unsettled.

# Identification and pit efficiency Laser-engraved stripes match bar thickness, so you can identify parts quickly in the pit. That reduces time lost swapping bars between practice runs and helps avoid setup mistakes during events.

# Fitment The parts are specified to work with X4 and X4F rear suspension arms using the ball-bearing roll bar mounting system. Confirm your car uses that mounting configuration before ordering.

# What the release does not state The press release used by LiveRC lists the functional features and fitment but does not include pricing, regional availability, or part numbers. For those details consult Team Xray's official channels or authorized dealers.

# Bottom line These new 1.6mm and 1.8mm rear anti-roll bars provide incremental stiffness options for X4/X4F cars built with the ball-bearing roll bar mounts. Expect smoother bar rotation, quicker swaps, and easier visual identification in the pit thanks to the ball-bearing mounting, height-adjust screw, and laser-engraved stripes.
