Stifflers Seat Rail Extenders (1979 - 2004 Mustang) SRX-M01

Seat Rail Extenders (SRX-M01) - 1979–2004 Ford Mustang

Make your Fox/SN95 Mustang fit like it should. Stifflers’ Seat Rail Extenders move the front seat mounting points up to 4.25" rearward, giving taller drivers real legroom without hacking the floor. The new low-profile design hugs the factory floor pan for a clean, OE-like install and rock-solid feel.

Why You’ll Like Them

• Instant comfort: slides seat back up to 4.25" for better legroom and driving position.
