1955-1957 CHEVY BOLT-IN INDEPENDENT REAR SUSPENSION
COMPLETE BASE KIT STARTING AT $9,320
The Tri-Five HEIDTS Pro-G™ IRS is a true bolt-in, high horsepower Independent Rear Suspension System for 1955 through 1957 Chevy cars. This industry-leading design is based off the proven and award-winning HEIDTS Pro-G™
IRS geometry, while the bolt-in design means it can be installed on cars that are already complete or easily added to builds already underway. The Tri-Five 55-57 Chevy BOLT-IN INDEPENDENT REAR SUSPENSION also features several design enhancements to make exhaust routing easier.
