Preview: Speedtech Performance’s Overhead Cantilever Independent Rear Suspension (IRS) at SEMA 2024

At SEMA 2024, Speedtech Performance is excited to feature our Overhead Cantilever Independent Rear Suspension (IRS) system, designed for the ultimate balance of comfort, control, and performance. Whether you’re building a high-horsepower street machine or a track-ready monster, our IRS system is engineered to meet your demands. Here’s a look at what makes it stand out:

Overhead Cantilever Shocks for Optimal Comfort

One of the first things you’ll notice about our IRS setup is the unique overhead cantilever shock design. This feature provides an exceptional motion ratio, ensuring a smooth, comfortable ride even when tackling aggressive driving conditions. Whether you’re cruising or hitting high speeds, the design helps maintain consistent performance, reducing harshness on the road while maximizing handling precision.

Longer Control Arms for Superior Wheel Travel

Our IRS features longer control arms, giving your vehicle a more stable camber curve throughout wheel travel. This design reduces excessive camber changes, maintaining optimal tire contact with the road. This feature ensures better tire wear and improved grip, whether you’re on the street or the track.

Heavy-Duty 1200+ Horsepower Axles for High Performance

When building high-horsepower cars, the durability of the drivetrain is crucial. That’s why our IRS system comes standard with 1200-horsepower-rated axles. We understand the demands of high-power builds—whether it’s for Camaros, Chargers, or other performance vehicles. And if your build exceeds that, we offer upgrade options to ensure your rear suspension can handle anything you throw at it, even upwards of 1500+ horsepower.

Full Adjustability for Track and Street Tuning

One of the key advantages of an independent rear suspension is its tunability, and Speedtech’s IRS gives you full control over your setup. With adjustments for toe, camber, and caster, you can dial in your suspension for any driving situation. Whether you’re optimizing for comfort on the road or dialing in precision for the track, our IRS system ensures you have the flexibility to fine-tune your performance to your specific driving needs.

Pre-Assembled Parking Brake for Convenience

A small but important detail of our IRS system is the pre-assembled parking brake mechanism, which comes attached to the hub. Builders who have worked with other suspension systems will appreciate the convenience of this feature, saving time and effort during installation. It’s one of those thoughtful touches that we believe makes a big difference in the build process.
