Low Back Seat Shell Impact

EMPI Low Back ABS Seat Shell - Impact Series

Product Overview

The EMPI Low Back Seat Shell offers the classic styling of traditional fiberglass seats but with the modern advantage of high-quality ABS plastic construction. Unlike fiberglass, which can have rough edges and inconsistent thickness, this ABS shell provides a significantly smoother finish and uniform durability. It is an ideal choice for VW Beetles, dune buggies, sand rails, and any off-road project where a lightweight, low-profile seating solution is required.

Dimensions and Construction

Designed to fit a variety of custom interiors, this seat shell features the following measurements:

• Width: 18 inches at the widest point.
• Height: 23 inches from the base to the top of the backrest.
• Seat Depth: 15 inches from the backrest to the front edge of the bottom.
• Material: Impact-resistant ABS plastic.

Appletree Pro Tech Tips

1. Use Load-Spreading Washers: When mounting your ABS seat shell to a frame or slider, always use large fender washers on both the top and bottom of the mounting holes. Because ABS is more flexible than fiberglass, spreading the load across a larger surface area prevents the bolts from pulling through the plastic under stress or during rough off-road maneuvers.

2. Prep for Seat Covers: While the smooth finish of the ABS looks great on its own, most users prefer to add a seat cover. To ensure a professional fit, use a light mist of foam-safe spray adhesive on the shell before sliding the cover over your padding. This prevents the cover and foam from "creeping" or shifting while you are getting in and out of the vehicle.

3. Drilling Clean Holes: If you need to drill custom mounting holes, use a sharp wood bit or a specialized plastic drill bit. Standard metal bits can sometimes "grab" the ABS and cause it to crack if you apply too much pressure. Run your drill at a medium speed to ensure a clean cut without melting the plastic edges.
