Wauconda, IL, August 15, 2012 - Heidts Automotive Group used the 43rd Annual NSRA Street Rod Nationals Plus at Louisville, KY to introduce a bolt-in, high-horsepower Independent Rear Suspension System for 1955 through 1957 Chevrolet cars. This bolt-in rear suspension system is based of the proven and award-winning Pro-G IRS design and adds yet another popular vehicle to the ever-growing lineup of fully engineered front and rear suspension systems and components.
The Tri-Five Chevy owners have been asking us to develop a true, bolt-in IRS solution for them to put under their cars,” says Mike Hawley, Heidts Sales Manager. “These cars are hugely popular with both customers and our dealers and are built from mild to wild. This new bolt-in high horsepower Pro-G IRS will allow them to take the ride and handling of these classic builds to a whole new level of performance.”
“When we set out to develop this product, our engineering team had one goal: make the BEST bolt-in IRS solution on the market – period,” says Jim Shaw, one of the Engineering Team members at Heidts that developed the Tri-Five Pro-G IRS. “The bolt-in feature means this Pro-G IRS can be installed on cars that are already complete or easily added to builds already under way. The ’55 to ’57 Chevy chassis provided some unique challenges, but we addressed them all and even made a few design enhancements to make exhaust routing easier.”
“We know that this application is going to be a big hit with our dealers and will allow them to introduce Heidts’ award-winning design and engineering, along with our best-in-the-industry customer service to a whole new segment of hot rod and street rod customers,” adds Hawley.
