RPM rear A-arms for the Traxxas Slash 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 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 rear A-arms use stock suspension geometry and include stock rear toe angles.
RPM Slash 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 rear A-arms are sold in pairs. They are molded 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.
From the Manufacturer
RPM rear A-arms for the electric versions of the Traxxas Rustler, Monster Jam, and Stampede are stronger and more durable than stock versions, but we’ve also managed to eliminate over 7 grams of weight per arm. That’s 14 grams of unsprung weight eliminated with a single pair of rear A-arms. Coupled with a set of RPM front A-arms, the total weight loss exceeds 24 grams or almost a full ounce. We accomplished this without creating any weak points nor are our A-arms any more flexible than the stock versions. Additionally, we’veadjusted the shock mount locations slightly to allow more noticeable tuning adjustments when using the inner or outer shock mount holes (while the center hole remains in its stock location). While we were at it, we eliminated over 0.030” or 1/32” of slop from the inner arm mount and more than 0.010” or slightly less than 1/64” of slop at the outer hinge pin for an ultra-smooth, slop-free suspension system.
