Steel Leaf Spring Suspensions


RT™ Series is a durable steel spring suspension with a legacy of over 85 years of reliability in the most severe applications. Hendrickson-designed springs provide a consistent spring rate for longer life as the equalizing beams distribute load equally between both axles for improved traction
