RPM RPM80762 Front A-Arms ARRMA Typhon 4x4 Big Rock Crew Cab 4x4 Black

The RPM RPM80762 Front A-Arms are a more adjustable, more durable, and lighter replacement for the ARRMA Typhon 4x4 3S BLX and compatible Big Rock Crew Cab 4x4 versions. RPM added a second outer shock mount hole for additional ride height and trackability adjustment — the lower position reduces ride height for improved stability and faster corner speeds. Each arm is more than 5 grams lighter than stock, cut from indestructible engineering-grade nylon while retaining stock suspension geometry. Replaces ARRMA #AR330543.
