The Sparco 004903 HD aluminum side mounts add a reversible mounting-foot arrangement. That gives a fabricator more packaging choices when a compatible seat and base need a different footprint.

Selection and Installation

Reversing the feet changes the space needed on the base. Check access for fasteners and the seat’s specified side brackets before deciding that a wider platform will solve tunnel clearance.

Product FAQs

What does the reversible-foot design change?
The mounting legs can face in or out to suit the installation footprint. It does not make the brackets suitable for every shell or override a seat-specific approved mount requirement.
How do the HD aluminum mounts differ from 600W?
The HD brackets are larger than the standard aluminum mounts and have reversible feet. Sparco lists a 3.4 lb set weight and an anodized-silver finish for this HD version.
Can these replace an explicitly required seat-specific bracket?
A reversible foot only changes installation options. Use a seat-specific bracket where the seat manufacturer calls for one, rather than selecting HD mounts by material alone.
