What Are the Correct Replacement Leaf Springs for 6,000 lb Axle

Question:

I have a FA3005 Ragen 5th wheel toyhauler. After digging through my manuals I found out I have Alko axles and assume they’re 6k the tag on the axle is rusted and I can’t get the info off of it, my trailer ID tag is faded and the tag inside only gives me my CCC and not my axle size. My question is what would I need to replace all suspension hardware and leaf springs? I think I know what I need but want to make sure before I start ordering parts springs loaded were approx 25” eye to eye and axles are 35” center to center. I’m about to drive across the map east to west coast and do not want to encounter a catastrophic failure due to suspension parts breaking. Thanks in Advance.

There are leaf springs available with measurements close to 25" from center of spring eye to center of spring eye, though the correct one is going to depend on your axle capacity, which should be stamped onto the axle itself. Knowing this information is going to be important to get you the correctly rated springs.

The options for you are going to be 6-Leaf Double-Eye Spring # SP-222275 which is for 5,300 lb axles and is 24-7/8" from center of spring eye to center of spring eye. Please keep in mind that leaf springs can stretch over time and you said yours were approximately 25" so this measurement is not going to need to be exactly the same as your current springs.

The 5-Leaf Double-Eye Spring # e78SR is another potential option as it is rated for 6,000 lb axles and measures 25-1/4" from center of spring eye to center of spring eye. The other spring you may want to consider is the 6-Leaf Double-Eye Spring # e64SR which is for 7,000 lb axles measures 24-7/8" from the center of one spring eye to another. I've added links to video reviews of each of these parts for you to take a look at as well.

There are hanger kits for tandem axle trailers available as well such as # APT8; I'll link the page with each of those kits for you to take a look at so you can compare your hardware and find the correct kit.
