Team Associated ASC8321 Rear Axle Spacers Narrow

These narrow rear axle spacers set where the rear wheels sit on the axle of the Team Associated RC10L3O and RC10L4O. Machined from aluminum and measuring 3/8 x 1/4 x 1/8 inch, they are a direct replacement for the spacers originally fitted to the car.

On a pan car, rear track width is a genuine setup tool rather than an afterthought. Moving the wheels in or out changes how much the chassis rolls and how quickly the rear responds to steering input through the middle of a corner. Swapping spacers is the quickest way to make that change, because axle height, camber, and ride height all stay exactly where you left them.

Aluminum holds its dimensions far better than a worn plastic spacer, so wheel position stays repeatable run after run and the wheels sit square on the axle instead of wandering under load. Fit them to replace spacers that are worn or damaged, or add a set to the pit box so you can adjust rear track width between qualifiers and the main.
