The Reyco Granning model 74B suspension is fabricated for the most severe duty operations. This suspension features extra wide 4” springs, hangers, and bushings which spread the load over a much larger area to improve durability and reliability. Rated at 30K lbs. per axle, the Reyco Granning 74B suspension system is the standard by which all other extreme duty suspensions are judged.
