Designed for all model years of Monza and Vega with coil spring suspensions, these custom rear frame rails offer a lightweight, high-strength solution for modern tire clearance and chassis stiffening.

Crafted from 2" x 3" x .125" mild steel rectangular tubing, each rail is precision-formed using S&W's advanced CNC machinery to ensure consistent quality and durability. These are not OEM replacement rails, but instead a purpose-built solution for performance applications requiring a narrowed rear frame section.
