Team Associated ASC81585 RC8B4 Antiroll Bar Hardware

This hardware set covers the small parts that locate and retain the antiroll bars across the RC8B4 platform, fitting the RC8B4, RC8B4e, RC8B4.1, RC8B4.1e, RC8T4, RC8T4e, and RC8T4.2e.

Antiroll bar hardware sits in a high load, high vibration area of the car, and the pieces that hold the bar in position wear, strip, or simply disappear into the pit carpet over a season of racing and rebuilds. Fitting fresh parts restores precise, slop free bar movement, which is what makes roll stiffness tuning predictable: a bar change then produces the handling change you actually expect instead of being masked by play in the mounts.

These are direct factory replacements that install in the stock front and rear positions with no modification to the bulkheads or arms. Keeping a set in the pit box means a stripped fastener or a lost piece does not end your day, and it makes swapping between bar sizes between heats quicker and far less fiddly.
