Overview
The RPM Front Upper & Lower A-Arm Set for the Arrma Grom platform delivers race-ready durability for your mini-class RC vehicle. Designed specifically for the Grom versions of the Arrma Typhon, Granite, Quake, and Gorgon, these upgraded A-arms feature support beams that are up to 32% wider than stock, reinforced shock mounts, and beefed-up inner hinge pin bosses for maximum crash survivability during high-speed bashing sessions.
Built from RPM's legendary engineering-grade nylon composite in the USA, these A-arms combine lightweight construction with virtually indestructible strength. The 30-degree beveled leading and trailing edges reduce weight without compromising durability, while a second shock mount hole on the lower A-arms provides additional tunability for serious drivers seeking that competitive edge.
