From the Manufacturer RPM A-arms for the Traxxas Slash 4x4 are everything\nyou’ve come to expect from RPM and more! Take a look at everything we’ve done:\nWe eliminated the slop in the suspension system, tightening the tolerances\naround the hinge pins, reduced the fore and aft movement of the A-arms at both\nthe inner hinge pin and at the axle carriers by better than 90% and improved\nthe durability dramatically (they’re made by RPM, enough said). As a bonus, we\ncut 6.5 grams of weight off of each A-arm! That’s a total loss of just under\none ounce of weight simply by replacing your stock A-arms with the RPM\nversions! We can’t forget about how much better aesthetically the RPM versions\nlook either. RPM A-arms carry over our traditional look with our 30 degree\nleading and trailing edges, and huge bosses for the shocks and sway bar\nmounts. Additionally, you now have the option of a bit of color with either\nblue or black to choose from. RPM A-arms are molded in our trademark blend of\nincredibly durable nylons and are backed by an industry leading warranty. We\nproudly stand behind our products! Designed, manufactured and produced right\nhere in southern California in the USA!
