RPM A-arms for the B64 & B64D were designed to solve criticalissues reported to us by our customers. With stock A-arms, the amount of slopat the hinge-pins can cause your suspension settings to wander (we found asmuch as 0.003" or .076mm of clearance in the hinge pin holes of a stock set ofnew A-arms). Our hinge-pin holes are held to extremely strict tolerances, withno more than 0.0005" to 0.001" (.013 to .025mm) of clearance, an improvement ofnearly 300%!
Durability is also key to staying on-track! RPM customers have repeatedlyreported that stock A-arms break easily. Whether bashing or racing, RPMA-arms are the toughest A-arms on the market so a rough landing or a hit fromanother competitor won't take you out of the race! We also use in-line screwsto retain the outer hinge pins. Elimination of that extra hole increases thedurability of our arms tremendously.
RPM A-arms are light than stock A-arms as well, weighing 2 grams lessper A-arm (or 4 grams for the pair) lighter than stock. If you're looking toshed weight or be able to move more weight around to optimal positions, RPMA-arms are the best option.
With unmatched performance, extremely lightweight materials and the ability to lock in yoursuspension settings even after a wicked wreck, RPM A-arms willget you across the finish line every time!
