They’re here! RPM A-arms for the Traxxas Slash 4x4 are everything you’ve come to expect from RPM and more!


They 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, they 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 the RPM traditional look with our 30 degree leading and trailing edges, and huge bosses for the shock and sway bar mounts. Additionally, you now have the option of a bit of color with either blue or black to choose from.

RPM A-arms are molded in RPM 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!

RPM A-arms for the Traxxas Slash 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 4x4) due to strengthening designs that reduce the clearance around the rear axle.

These A-arms for the slash 4x4 i put on my Stampede 4x4 and i took it to my local skate park and i jumped it about 12 to 14ft in the air and come down on the right front a-arm and nothing broke but if i didn't have the big bores i would have bent a shock shaft.

These things are Quality,and they aren't bluffing. Strong, dependable, and with a superior, and better disign out doing the stock arms. They will always be ready to take on most abuse.

RPM Traxxas Slash 4x4 Front or Rear A-arms (Black)
After a trip to the local skate park and literally a few jumps later I broke a front control arm. I ordered 2 sets and now i have the stocks as spares. These seem like they are as brittle.

Well, after my friend's slash 4X4 was run over by a car, he went to RPM due to their reputation. RPM has stood up to their reputation since he bashes very hard, and sometimes hits jumps at bad angles, he even once drove literally through his wooden jump at full speed, and his RPM a-arms didn't break, he had them up front. For my b-day, he was so satisfied with his a-arms, he bought me a set for my 2wd drive slash, I am sure they will also uphold the reputation of RPM.

Awesome Product. They will eventually bend with enough abuse. But hands down the best addition to my Slash 4x4
