Description

Additional Information:

Front small block and big block springs for Impala, El Camino, and Biscayne 1958, 1959, 1960, 1961, 1962, 1963, and 1964 models ranged from 300 pounds per inch to 400 inch pounds.

The four different rates most used are 300, 325, 375, and 400 pounds. All station wagon springs were rated at 400 pounds per inch and surprisingly all 58 models had 400 pound springs. The 1959 Impala and newer generally had 300 pound springs while Biscayne and Belair came in with 325 and 375. These rates were used for 6 cylinder, 283, and 327 applications.

The 409 cars actually had 300 pound springs; unless it was in a station wagon, then a 400 pound spring was used. Ride heights also varied. Front end weights all hovered around 2000 with a variance of 150 pounds up or down.
