This is a wider actuating bar for sliders utilizing a sparco style release. It is wider than what comes with the stock sliders, allowing for use of some of the wider shells available (Cobra's GT width seats, Recaro's XL width).

We've found that you'll generally need to massage this piece to make it fit your situation correctly. It can be bent fairly easily. It is designed to work in 911, 944, 996 & Boxster applications where the seat tracks are 16" wide.
