RPM A-arms for the Traxxas Slash 4×4, Rustler 4×4, Hoss 4×4 & Stampede 4×4 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.
RPM A-arms are molded in our trademark blend of incredibly durable nylons.
Tech Notes: Replaces stock Traxxas TRX3655R & TRX3655X. RPM A-arms will not fit ST versions of the Rally (please see RPM73362). 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.
