Stifflers Seat Rail Extenders
Make your 1979-2004 Mustang more comfortable for taller drivers and passengers with the help of these seat rail extenders from Stifflers! There is nothing worse than not fitting well in your Mustang and making the ride uncomfortable with squished legs and your head hitting the roof. Most seat rail extensions will raise the seat, reducing headroom as a trade-off for more legroom. Stifflers extenders move the seat back 4.25" further to provide both increased legroom and even slightly more headroom. Designed to contour tightly to the floor pan using custom-formed thick steel rails and powder-coated for long life. No extra holes need to be drilled for an easy bolt-in installation in minutes with OE-style hardware. One kit will cover one power or manual seat track on your 1979-2004 Mustangs.
