Introducing The Total Cost Involved Engineering New American Made 1949, 1950, 1951, 1952, 1953, 1954 Chevy Car rear parabolic leaf spring suspension kit. Parabolic springs differ from conventional leaf springs. Parabolic springs run parallel to each other and come in contact with each other only at the center and end mounting points. This reduces the weight of the spring, improves ride quality and eliminates squeaks. This TCI Engineering product provides your vehicle with strength, durability, proven quality greater flexibility, 28% weight savings, better fuel mileage with less vehicle weight, and this suspension will not rob your classic of performance. This leaf design is characterized by fewer leafs whose thickness varies from center to ends following a parabolic curve. In this leaf design, inter-leaf friction is unwanted, and therefore there is only contact between the springs at the ends and at the center where the axle is connected. The characteristic of parabolic springs is better ride quality and not being as "stiff" as conventional "multi-leaf springs". NOTE: Drops rear end 4"
