Don’t let a broken front A-arm end your day of fun. RPM A-arms for the Helion Dominus SC, SCv2 & TR 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 both the hinge pins and the pivot balls to help prevent hard hits from ripping either part out of the A-arm. We’ve also tightened up the tolerances around the hinge pins by over 0.005” (0.13mm) to reduce slop in the suspension system and improve retention of camber, caster and toe angle settings.
If you’re in the market for a replacement set of A-arms for your Dominus, you can’t beat American made, RPM parts!
Tech Notes: RPM A-arms for the Dominus SC, SCv2 & TR are sold as a set of one upper and one lower A-arm. To complete one vehicle, two sets are required. RPM Dominus arms replace the upper arm from Helion #HLNA0080 while the RPM lower arm replaces the stock lower arm from Helion #HLNA0081.
