(Tech Notes For 80592 Rear Arms)Stock rear axle carriers have an upper and lower hinge pin hole. RPM Slash rear A-arms only allow the use of the original, lower hole location to be used. The upper axle carrier hole (which would lower the ride height in the back too much) cannot be used. To lower the rear end of the truck, RPM recommends using the outer shock mount hole positions in the A-arm
RPM front A-arms for the Electric versions of the Slash are sold in pairs and are available in a variety of colors. These A-arms are molded with what is fast becoming an RPM trademark design of angled leading and trailing edges to reduce frontal edge mass and improve the a-arm's ability to ride up and over tall obstacles instead of slamming into them. RPM A-arms are extremely rigid for superior ride and stability over the roughest tracks and terrain.
