RPM A-arms for the Helion Invictus MT are the strongest A-arms available! Each RPM A-arm is molded from our blend of engineering grade nylons for unmatched strength and durability. Crucial design elements include oversized bosses around the hinge pins and the pivot balls to help prevent hard hits from ripping them out of the A-arm. We’ve also tightened up the tolerances around the hinge pins by more than 0.005” (0.13mm) to reduce slop in the suspension system and improve camber, caster and toe angle consistency.
If you’ve damaged your stock A-arms or just want the toughest replacement front A-arms for your Invictus, you can’t beat American made, RPM parts!
Tech Notes: RPM73872 A-arms are sold as a set of one upper and one lower A-arm. To complete one vehicle, two sets are required. RPM Invictus arms replace the upper arm from Helion #HLNA0256 while the RPM lower arm replaces the stock lower arm from Helion #HLNA0255.
