GMS Lower Chassis Slug − 1/4” / 1/2” Aluminum

The GMS Lower Chassis Slug Aluminum 1/4” : 1/2” is a single, one-piece stepped chassis slug, not stacked or shimmed. The two measurements represent different thicknesses within the same slug, allowing for controlled and repeatable suspension spacing while maintaining maximum strength and rigidity.

Precision machined from lightweight aluminum, this stepped slug is designed for Super Late Model chassis applications where fine adjustments to suspension mounting height and geometry are critical. The one-piece design eliminates flex, misalignment, and tolerance stack-up that can occur with multiple spacers.

This component is ideal for teams looking to make accurate, durable setup changes without introducing unnecessary complexity or weight.
