After the release of the “Flat” front a-arms for the Team Associated B6 and B6D, RPM introduced their new Gull Wing front A-arms. With stock A-arms, the amount of slop at the hinge-pins can cause your suspension settings to wander (RPM found as much as 0.003” or .076mm of clearance in the hinge pin holes of a stock set of A-arms). RPM hinge-pin holes are held to extremely strict tolerances, with no more than 0.0005” to 0.001” (.013 to .025mm) of clearance, an improvement of nearly 300%. RPM A-arms are strong but extremely lightweight and they have the ability to hold your suspension settings even after a wicked wreck.
