Seat rail conversion adapter kit

Seat rail conversion adapter kit for selected aftermarket seat installations where the seat mounting pattern does not directly match the seat rail.

This kit is sold per seat rail side. If you are fitting both driver and passenger seats, order two kits.

Before ordering: please measure the underside of your seat and compare it with the mounting dimensions below. If you are unsure, contact us with your seat brand, seat model, rail application and clear photos of the underside of the seat.

What this adapter does

This adapter is used where the seat is suitable for the application, but the seat mounting pattern needs to be converted to suit the rail. It sits between the seat and the seat rail to help match the required mounting pattern.

Mounting dimensions

The adapter has two main mounting patterns. Please check both the front-to-rear and left-to-right measurements against your seat before ordering.

Kit contents

• Adapter bars × 2
• M8 × 20 mm hex bolts × 4
• M8 flat washers × 4
• M8 flange nuts × 4
• 3 mm spacers × 4

Hardware notes

• The M8 × 20 mm bolts and M8 flat washers are seat-mounting hardware.
• If this adapter is ordered together with a seat rail, some seat-mounting hardware may already be supplied with the rail and may not be duplicated.
• The 3 mm spacers are used for selected Sparco seat fitments.

Important fitment notes

• Sold per seat rail side.
• One kit is required per seat rail. Order two kits for a driver and passenger pair.
• Please check your seat base measurements before ordering.
• This adapter does not make every seat compatible with every rail or vehicle. Seat width, mounting pattern, seat base design and final seating position still need to be checked.
• Seat and seat rail changes may require certification or inspection depending on the final installation.
