RPM A-arms for the Helion Animus 18SC & 18TR eliminate most of the play at the hinge pins and axle carriers. A tighter suspension system means more precise control of the truck through more accurate camber, caster and toe angle settings. Each set of RPM Helion A-arms comes complete with both front A-arms and both rear A-arms. Molded in black or red, they come with a lifetime warranty against breakage.
