Product Description

The Cusco 246 541 A Type OS Rear Strut-Tower Brace is engineered for the iconic Datsun/Nissan S30-series vehicles -- specifically the 1970-73 240Z, 1974-75 260Z, and 1975-78 280Z. This high-performance brace enhances rigidity across the rear shock towers and body hoop, reducing flex under hard cornering and delivering improved handling feedback.

Constructed from a lightweight yet strong tubular aluminum oval shaft and backed by Cusco's renowned build quality and hardware package, this Type OS brace offers a perfect balance of strength and weight savings for enthusiasts. Simple bolt-on installation uses existing factory mounting points and gives immediate improvement to rear chassis stiffness--ideal for both street and track builds of the S30 Z-cars.
