General Information1. A Hutchens part number is stamped on all of the steel springs that we supply. For springs with clips, our part number is stamped

on the outside of the spring clip. On springs without clips and with hooks, our part number is stamped on the outside of the hook. All other springs are stamped in a visible location on one of the spring leaves.

2. All springs for the 440 and 900 single point suspensions are 5” wide. The 11436-00 and 22429-01 springs are 4” wide. All other springs are 3” wide.

3. The Gross Axle Weight Rating (GAWR) or Gross Tandem Weight Rating (GTWR) is listed for each spring.

4. Weights given are per spring.

5. Deflection charts are per spring NOT per axle.

6. H.D. (Heavy Duty) springs are recommended for widespread applications.

7. Single leaf springs are NOT recommended for tri-axle applications.
