The Reyco Granning model 79KB was designed as a single steel spring drive axle spring suspension that combines high weight capacity with excellent ride characteristics. Ride quality is enhanced by the extra-long spring length while rugged cast components can carry load ratings up to 31,000 lb.

With a wide range of options, the 79KB is one of the most customizable suspensions available for Class 5 through Class 8 trucks and tractors. It’s an ideal choice for everything from city delivery to extreme-duty fire and rescue.
