Description
RPM customers have reported that stock B64 & B64D 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! To increase durability, we use the best possible engineering grade nylons as well as using in-line screws to retain the outer hinge pins. Elimination of that extra hole increases the durability of our B64 arms tremendously.
Also key to winning is the ability to lock in suspension settings. 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). Our 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 also come in under stock weight, weighing 2 grams less per A-arm (or 4 grams for the pair). If you’re looking to shed weight or be able to move more weight to optimal positions, RPM A-arms are the way to go.
With unmatched performance, extremely lightweight materials and the ability to lock in your suspension settings even after a wicked wreck, RPM A-arms will get you across the finish line every time!
Tech Notes: RPM #73822 replaces stock Associated #92048.
