RPM rear A-arms for the Traxxas Slash 2wd are designed specifically for the Slash they are not multi-platform A-arms like the stock versions.Our first design challenge was to beef up our version of the Slash rear A-arms to handle some serious abuse.The material around the inner and outer hinge pins has been increased by 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 set of our #80382 Rear Bearing Carriers RPM Slash rear A-arms use stock suspension geometry and include stock rear toe angles.RPM Slash 2wd rear A-arms are not only stronger and more durable than stock, they are also more rigid and less flexible too, making them the perfect addition to those race-level Slashes on the track.Additionally, the new geometry design leaves no place for dirt and rocks to get caught in the lower A-arm and reduces the chances of rocks and debris getting stuck between the axle and the arm.RPM Slash 2wd rear A-arms are sold in pairs.They are moulded in our nearly indestructible blend of nylons and are sold in either black our blue.These A-arms are backed by our limited lifetime warranty against breakage as well for confidence-inspiring durability and performance.
