RPM rear A-arms for the Traxxas Slash 2wd are designed specifically for the electric version of the Slash � they are not multi-platform A-arms like the stock versions. Our first design challenge was to beef up the rear A-arms to handle some serious abuse. The material around the inner and outer hinge pins has been increased by a whopping 64%! We then eliminated all of the unnecessary holes and shock mounts that would be needed on other vehicles but not on the Slash, which significantly reduced the weight of our A-arms while improving crash durability. Even after all of the increased muscle has been factored in, our A-arms still come in at over 10% lighter than the original arms! Our final design task was to improve the fit and finish and what we came up with will eliminate most of the slop in the rear suspension system! The Slash owner can tighten things up to near perfect out back simply by adding in a set of our 80382 Rear Bearing Carriers currently available. RPM Slash 2wd rear A-arms use stock suspension
