While RPM A-arms are stronger than stock, they’ve also been designed with added bellcrank clearance to protect that hard-to-get bellcrank from heavy, full compression suspension slams. Added protection means fewer trips to the pits and more time on the rocks.
Our Rock Rey suspension arms are also extremely light, weighing in at a whopping 11 grams per pair lighter than stock A-arms! Less unsprung weight means faster acceleration / braking and better suspension performance. It also allows you to move weight where you need it, adding more tunability to an already versatile rock racer.
RPM A-arms are the best aftermarket alternative for guaranteed tough, American made parts!
Tech Notes: RPM Rock Rey A-arms are sold in pairs and replace stock Losi #LOS234011.
