RPM ARRMA GROM UPPER & LOWER FRONT A-ARMS (SET A)

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.

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

On top of our strengthening upgrades, we 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 our legendary engineering-grade nylon, ultra-lightweight yet virtually indestructible. Whether you're bashing hard or flying fast, don’t trust your ride to anything less. Trust RPM.
