RPM R/C Products - Traxxas Slash 4×4, Stampede 4×4, Rustler 4×4 & Rally Front or Rear A-arms – Black Storage & Transportation - High carbon steel constructionRPM A arms for the Traxxas Slash 44, Stampede 44 & Rustler 44 are everything youve come to expect from RPM, and more! RPM 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 (theyre made by RPM, enough said). As a bonus, they cut 6. 5 grams of weight
