Product Detail

RPM A-arms for the Traxxas Slash 4x4, Rustler 4x4, Hoss 4x4 & Stampede 4x4 are everything you’ve come to expect from RPM and more! Take a look at everything we’ve done:

We eliminated the slop in the suspension system, tightening the tolerances around the hinge pins, reduced the fore and aft movement of the A-arms at both the inner hinge pin and at the axle carriers by better than 90% and improved the durability dramatically (they’re made by RPM, enough said). As a bonus, we cut 6.5 grams of weight off of each A-arm*! That’s a total loss of just under one ounce of weight simply by replacing your stock A-arms with the RPM versions!

We can’t forget about how much better aesthetically the RPM versions look either. RPM A-arms carry over our traditional look with our 30 degree leading and trailing edges, and huge bosses for the shocks and sway bar mounts. Additionally, you now have the option of a bit of color with black, blue, green and red to choose from.

RPM A-arms are molded in our trademark blend of incredibly durable nylons and are backed by an industry leading warranty. We proudly stand behind our products! Designed, manufactured and produced right here in southern California in the USA!

Tech Notes: Replaces stock Traxxas #3655R & #3655X. RPM A-arms will not fit ST versions of the Rally (please see RPM #73362). RPM arms are sold in sets of 1 – left and 1 – right A-arm in each package. Two packages will be needed to complete one truck. The upper hinge pin hole of the rear axle carriers cannot be used (not a stock location for the Slash 4×4) due to strengthening designs that reduce the clearance around the rear axle.
