RPM Front A-arms For Arrma Grom Vehicles

RPM front A-arms for Arrma Grom vehicles are now available. Beef up the Grom version of your Arrma Typhon, Granite, Quake or Gorgon with RPM Upper and Lower Front A-Arms. Small-scale doesn’t mean small stakes. These mini rockets push serious speed, and the stock components just can’t keep up. That’s where RPM steps in.

RPM Front A-arms For Arrma Grom Vehicles

RPM’s Arrma Grom Upper and Lower Front A-arms (Set A) are engineered for strength where it counts most. RPM added muscular upgrades like 30-degree beveled leading and trailing edges to reduce weight without compromising strength. The A-arm support beams are as much as 32-percent wider than stock. RPM also reinforced the shock mounts, and beefed-up inner hinge pin bosses where possible for next-level toughness.

On top of RPM’s strengthening upgrades, they also added a second shock mount hole on the lower a-arms. Now you can tune your ride to your driving style and track conditions. The second hole sits to the outside of the stock shock mount location. This wider position lowers the ride height and CG, making your Grom a corner-carving monster.

All of this is manufactured in the USA using RPM’s legendary engineering-grade nylon, ultra-lightweight yet virtually indestructible.

Tech Notes: Replaces the front upper and lower A-arms from stock Arrma #ARA330809. Does not fit the Mojave Grom. RPM #72292 does not include pivot balls. Must reuse stock Arrma pivot balls or acquire Arrma #ARA330805 pivot balls. One package includes two upper front and two lower front A-arms.
