Team Associated ASC81528 RC8B4 Front Lower Arms

These front lower suspension arms are the primary links between the chassis and the front hubs on the Team Associated RC8B4 1/8 scale buggy. Each arm pivots on the front hinge pins and carries the lower shock mount, so it handles nearly all of the suspension load from landings, ruts, and curbs while defining the front roll center and camber path as the wheel travels.

That makes the lower arms one of the most abused parts on the car and one of the first things worth checking after a heavy crash. A cracked arm, an elongated hinge pin bore, or a worn shock mount hole adds play that dulls steering feel and lets alignment wander between runs. Fresh arms bring back tight, predictable front end response.

They fit the RC8B4, RC8B4e, RC8B4.1, and RC8B4.1e, covering both nitro and electric builds on the platform. These are direct factory replacements that use your existing hinge pins, inserts, and shock hardware, so the swap requires no modification to surrounding parts.
