3500 lb Drop Axle Guidance
- Minimum (No Brakes): 14" total (7" overhang per side)
- Minimum (With Brakes): 14" total (7" overhang per side)
- Maximum Overhang: 18" total (9" overhang per side)
Example for a 75" Hub Face:
Minimum Spring Center (No Brakes): 75" - 14" = 61" spring center.
Minimum Spring Center (With Brakes): 75" - 14" = 61" spring center.
Maximum Spring Center: 75" - 18" = 57" spring center.
For a 75" hub face, the recommended spring center range is between 57" and 61", depending on whether the axle has brakes.
Overhang Summary
Axle overhang is the distance from the hub face to the spring center.
A shorter overhang (wider spring center) increases axle strength and improves load handling.
A longer overhang (narrower spring center) increases leverage but reduces stability and axle capacity.
Match existing spring centers when possible. This information is for guidance only.
