GMS Upper Chassis Slug Aluminum 0/0 : 3/4

The GMS Upper Chassis Slug Aluminum 0/0 : 3/4 is a single, one-piece stepped chassis slug used to create up to 3/4 inch of spacing at the upper chassis mounting point on Super Late Model suspension systems. The “0” reference indicates a flush reference face, not an adjustable zero setting.

Machined from lightweight, corrosion-resistant aluminum, this slug incorporates the full stepped profile into one solid component, eliminating the need for stacked shims or spacers. The one-piece design maintains rigidity, prevents tolerance stack-up, and ensures consistent geometry under load.

This slug is intended for racers who want clean, repeatable chassis spacing with maximum durability and minimal complexity during setup changes.
