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.

Video Transcript for Redline Trailer Suspension PR427 Review

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 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

Do you have a question about this Trailer Suspension?


  • 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....

  • Trailer Spring Kit # 2-1020 Recommendation for an Old Boat Trailer Converted to a ATV Trailer
  • It sounds like you may have a vehicle leaf spring on your old boat trailer as we do not carry any leaf springs that are that length. The longest one we have is 27 inches long and is designed for 3,000 lb axles. That spring is the Redline Leaf Spring # PR427. The leaf spring that would closely match the axle capacity of your trailer would be the Redline Trailer Suspension # 1020. For a kit I would recommend a 3-Leaf, Double-Eye Spring Kit for 2,000-lb Trailer Axles # 2-1020. You...

The leaf spring is only 20-1/4 inches long. If you need a leaf spring that is 27 inches long and 1-3/4 inches wide, I recommend the Trailer Leaf Spring, part # PR427. With this spring, you would need the 2-1/2 inch Round U-Bolts, part # 175668, and...

  • Leaf Spring Replacement On trailer With Square Axle
  • You will want to take some measurements to make certain the parts you want to replace will be a good fit for you. You will need to know the weight capacity of the trailer axle on your trailer. this can usually be found on a sticker or plate attached to the axle. If you cannot find the weight capacity, you can get the numbers of the bearings and seals and we can narrow that down. I have attached a photo that shows where you can normally find the bearing and seal numbers. The 4-Leaf Double...

  • 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...

  • Leaf Spring Replacement Recommendation for a Boat Trailer with a 3000 lb Axle
  • The 4-Leaf Double-Eye Spring # PR427 that you referenced that is 27 inches long should work well for you. Typically you want the spring a little bit shorter than the hanger distance (about 1/2 inch) but you're close enough that it should work just fine. I attached an FAQ article on trailer suspension for you to check out also.

  • Replacement Leaf Springs for Trailer Suspension Wore Out on One Side of Boat Trailer
  • The first thing you will want to check is the load on the trailer. If it is rated for 3,000 pounds then you will want to stay at or under that. Going with higher capacity springs will give the the exact problem you are experiencing. We carry 1 spring that is rated for 1500 pounds, # PR427. It measures 27 inches long from eye center to eye center. Always replace leaf springs in pairs. Otherwise the axle can get out of alignment which is what might have happen when the tire was rubbing...

  • Should the Space Between Tandem Axle Trailer Tires Be the Same On Both Sides of the Trailer
  • Is there more weight on one side of the trailer? If so, you would want to make sure the load is distributed evenly from side to side. Are you on level ground when you measured the distance between the tires? If not, that would cause one side of the suspension to have more of a load on it. I would measure the distance between the spring hangers on both sides just to make sure the problem is the springs and not where they are attached on your trailer. If everything checks out it might...

Using these springs would reduce your weight carrying capacity to 3,000 lbs per axle. The longest leaf springs we carry for 3,500 lb axle is 25-1/4 inches long, part # PR4B.

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...

  • Hanger Spacing for Trailer Double-Eye Leaf Spring PR427
  • Actually, the hanger spacing will need to be approximately 25-3/4 inches measuring on center. One end of the leaf spring will overshoot the hanger and the shackle makes up the difference. This allows both ends of the spring to be at the same or close height and allow the suspension to move like it needs to. I have included a link to our help article on double-eye suspension for you.

Springs can flatten out or otherwise lose shape over time so the measurements you get may not match exactly with a new spring. We have one double eye spring that is a good candidate based on the measurement you provided. Spring # 1724 measures 23-1/4 inches from eye center to eye center. It has...

You are going to have to install new hangers anyway so you really wouldn't need to match up the lengths of your old springs. Near the coupler of the trailer there should be a plate or sticker with the axle capacity of your trailer listed. Once you have...

This is designed for a 3,000 lb axle and may give you a really stiff ride. Another option would be to choose a leaf spring that is rated for 2,000 lb axles like part # 1020 and then weld on a new hanger because the eye center to eye center length for this leaf spring is 20-1/4 inches.

You should measure the center of the spring eye-to-eye and choose a leaf spring replacement about an inch shorter.

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.

  • Availability of 27-3/4 Double Eye Leaf Springs
  • We do not manufacture leaf springs, so we can't do custom springs.

The best way to get a measurement that's as accurate as possible is to jack up the trailer, then take the length measurement. The closest match we offer to the length you mentioned would be part # PR427 which is 27 inches long by 1-3/4 inches wide, which is rated at 3000 lbs...

First you could move either the front or rear hangers to get a spacing of 20 inches on center which will allow you to use a properly rated spring, # 1020. This will require having the existing hangers cut off and welded on by a professional welder. The other option is to use a longer spring, such as # PR427, which is 27...

  • Thank you for providing the detailed description of your broken 4-leaf spring.

If the spring has an eye on both ends then it is a double-eye spring whose width is probably 1-3/4-inches rather than 2-inches.
