The Avid 1/8th Hex Track Width Spacers (17mm) are a great way to adjust the width on any 8th scale buggy or truggy without having to change out your hubs. Typically this will help stabilize a vehicle by increasing track width and scrub.

You can choose from two sizes, 1.0mm and 0.5mm, or just order a set that includes 6 of each size.
