How Many Leaves are on 3,500 lb Trailer Axle Leaf Springs

Question

Question:

I have tandem 3500 axles. I want to put new springs on. Are there heavy duty or 5 or 6 leaf springs available? I changed drums and brakes a few years back which I purchased from you. Wish I had changed springs at that time. I know I need to get you more information and I will. Thanks

The leaf springs we offer for 3,500 lb axles are 4-leaf setups like the part # e54SR which is 25-1/8 inch long. The next capacity we offer higher than this is 4,500 lb which is also a 6-leaf setup with the part number # e27SR. This one happens to be 26 inches long. Going with additional leaves would not gain you anything substantial in terms of capacity and reliability so I would easily recommend a 4-leaf setup.

Answer 4

The most popular trailer wheel bolt pattern is the 5 on 4-1/2 inch bolt pattern and as far as we are aware the bolt pattern you mentioned is not used on trailers at all. So my bet is you probably have the 5 on 4-1/2 inch. I attached a help article…

You can use leaf springs that are rated higher than the axle without any issues as long as they measure the correct measurement for your trailer. For example the 6-leaf double eye spring for 7,000 lb axles part #e64SR measures 24-7/8" eye to…
