Leaf springs are an integral part of your trailer suspension system. The double-eye spring is suspended at the ends by hangers that attach to its eye or, in the case of tandem-axle or triple-axle systems, into hangers in the front and rear and an equalizer or equalizers in the center. To determine the type of hangers or hanger kit you need, you must know the specific type of leaf spring you have, as well as your axle diameter and capacity. Depending on the hanger kits used with them, springs can be configured to work for single-, tandem- or triple-axle applications.

Please Note: To ensure proper axle alignment and suspension performance, leaf springs should always be replaced in pairs.

Today we are going to be taking a look at part number PR424, the 4-Leaf Double-Eye Spring for 3,000-lb Axles. Before ordering a spring for your trailer, there are a few things you do need to know first. This spring measures 27 inches long by 1 3/4 inches wide. You do need to know the springs half-length which is measured from the center of the eye mount to the center of the spring here at the leaf bolt. This spring has a 13 1-2 inch half-length. One measurement you will need to do is to measure the spring height. To do that, you will draw an imaginary line from the center of the mounting eye to the center of the mounting eye.

And using that imaginary line you will measure from it to the spring surface. In this case, it is 2 3/4 inches. You will notice that these springs has two 9/16 mounting points with nylon bushings. These nylon bushings help to prevent metal on metal contact while the spring is installed on the trailer. It does have 4 leaves in it giving it a 1,500-lb load capacity. When you multiply that by two, you get your 3,000-lb total load capacity per axle. And that does it for part number PR427, the 4-Leaf Double-Eyed Spring for 3,000-lb axles.

I purchased the 3000# axle springs and all mounting hardware to replace the old ones on my 1963 travel trailer. My trailer no longer leans to the left and goes down the road better than new. I should have done it many year ago. I received my package on time and installation was easy and fit perfect. Thanks Bridget 116826

The leaf springs were just what I needed, they mounted up perfectly. The only problem I have is the old ones were so flattened that with the new leaf springs, I have to buy a new hitch with less drop, thanks. 85671

Received exactly what I ordered and fast too. I have ordered from etrailer before and spent some time searching for best price on these springs, just to make sure their prices were good. Save yourself some time and just use etrailer, they're the best. I would definitely recommend them.57098

The price was right and shipping was fast, and the video on measuring made it easy to be sure I was ordering the right part for my trailer. What's not to like? The only mistake I made was in not ordering all the hardware (U-Bolt kit, shackle bolts, and shackle straps) all at the same time. Although the videos say these parts can be reused, mine were rusty enough that they were really hard to get apart and then back together, even though they were only a year old.41932

  • Double Eye Leaf Springs for Boat Trailer, Stretched Out
  • Before you can pick out a set of leaf springs for your boat you need to find out the weight rating of your trailer axle. Then you will need to purchase leaf springs that are each 1/2 of the axle rating. The # PR427 is rated for 1500 pounds so if your boat trailer axle is a 3000 pound axle then I would say that # PR427 is the correct leaf spring for your axle. Due to wear and different manufacturing tolerances the spring dimensions will be slightly different especially for length measurements

  • Leveling a 5th Wheel Trailer that Leans to One Side
  • I recommend adding some suspension enhancement that is going to help keep the trailer level. We have several options available for trailers and I have included a link to them for you. This will also help improve the overall ride quality and extend the life of the stock suspension. Since you have 2 axles you would need to use 2 kits. Also, you would not want to use the springs on just one side because then you will have the same problem on the opposite side! I do not recommend using different

  • How to Find the Length of a Leaf Spring on a 1985 Rustler 2 Horse Trailer
  • It is best to measure trailer leaf springs without a load on them. It would be best to remove the spring from the trailer completely, otherwise you could jack the trailer up. That will give you the most accurate center eye to center eye length measurements. The next factor that you will want to consider is that springs flatten out over time. If these are the original springs and they measure 27 inches from eye to eye, the original length could have been around 25 to 26 inches. If you can

  • How to Determine the Correct Replacement Leaf Springs for a 1985 Rustler 2-H Montrose BP Trailer
  • To find the correct replacement leaf springs for your 1985 Rustler tandem axle trailer you will need to measure the spring with the weight off of it. You can do this by either removing a spring or by jacking up one side of trailer and measuring the spring on that side. I have included a picture showing the important measurements for a double-eye leaf spring. To get the best information on the axle capacity there should be a sticker or plate on the trailer frame/tongue somewhere with the axle

  • Correct Double-Eye Leaf Springs For Seabird Boat Trailer
  • Since leaf springs can flatten out a bit over time it is best to measure trailer leaf springs with no load on them. The best way would be to remove the spring from the trailer completely. Another way would be to jack the trailer up, taking weight off the springs you have installed. That will give you the most accurate center eye to center eye length measurements. The # PR427 is rated for 1500 pounds so if your boat trailer axle is a 3000 pound axle then most likely part # PR427 is the right l
