What is the main benefit of installing a rear strut bar?

A rear strut bar connects the two rear strut towers on your vehicle's chassis. This reinforcement helps to reduce body flex and chassis distortion, particularly during cornering, leading to improved handling and a more stable feel.

Is this strut bar a direct bolt-on installation for my 1970-1973 240Z?

Yes, this Cusco strut bar is designed to fit the 1970-1973 240Z chassis and typically bolts directly to the existing mounting points on the rear strut towers. Always refer to the manufacturer's installation instructions for specific details.

What material is the Cusco Rear Strut Bar made from?

The Cusco Rear Strut Bar is constructed from a strong 32mm steel tube. This material choice provides a good balance of rigidity and weight to effectively stiffen the rear chassis.

Product Details

The Cusco OS (Over-Steering) Rear Strut Bar is built from a strong 32mm steel tube, a solid choice for reinforcing the chassis of your 1970-1973 Nissan 240Z. When you're pushing your Z through corners, the body of the car can flex, especially between the rear strut towers. This bar ties those towers together, making the whole rear end feel more connected and responsive. It's a straightforward way to get improved handling without major modifications.

Cusco is well-known for making solid suspension components, and this strut bar is no exception. The 32mm steel tubing offers a good balance of strength and weight, helping to stiffen the rear of your 240Z. Installation is typically a bolt-on affair, connecting directly to the existing mounting points on your rear strut towers. You'll notice a difference in how the car handles during spirited driving, with less body roll and a more predictable feel when you turn.

This bar is specifically designed for the 240Z chassis, ensuring it fits right. If you're looking to get more out of your classic Z's suspension, this Cusco strut bar is a popular option for a reason.
