You can’t go fast if your suspension settings don’t stay locked in. With stock A-arms, the amount of slop at the hinge-pins can cause your suspension settings to wander. We found as much as 0.003” or .076mm of clearance in the hinge pin holes of a stock set of new A-arms. Not with RPM A-arms! Our hinge-pin holes are held to extremely strict tolerances! Our arms have no more than 0.0005” to 0.001” (.013 to .025mm) of clearance. That’s an improvement of nearly 300%! We also use in-line screws to retain the outer hinge pins while we ditch the inside retaining screws for shoulders in the hinge pin holes. This results in a weight reduction of 1.75 grams per A-arm (or 3.5 grams per pair) less than stock! Durability is also key to staying on-track! RPM customers have repeatedly reported that stock A-arms break easily. Whether bashing or racing, RPM A-arms are the toughest A-arms on the market so a rough landing or a hit from another competitor won’t take you out of the race! With unmatched performance, extremely lightweight materials and the ability to hold your suspension settings even after a wicked wreck, RPM A-arms will get you across the finish line EVERY time! Tech Notes: RPM #81372 replaces stock Associated #91671 and are sold in pairs (1 – left & 1 – right).
