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 PR626 Review
Today were going to be reviewing number PR626, the 6-Leaf Double-Eye Spring for 4,500-lb Axles.When ordering a spring there are a few things you do need to know first. This spring measures 26 inches long by 1 inches wide. You will need to know the springs half-length which is measured from the center of the mounting eye to the center of the spring here at the leaf bolt. This spring has a 13-inch half-length. One final measurement you will need to know is the spring height. To get the spring height youll need to draw an imaginary line from the center of the mounting eye to the center of the mounting eye.
Using that imaginary line youll actually measure from it to the spring surface giving you the spring height. In this case, it is 3 inches.Youll notice that mounting points are two 9/16 holes with nylon bushings in them. These nylon bushings help to prevent metal on metal contact while the spring is mounted on the trailer.And that does it for part number PR626, the 6-Leaf Double-Eyed Spring for 4,500-lb axles. .

- Recommendation for Replacing Trailer Leaf Springs on Triple Axle Trailer
- If you have 6000 pound axles then the Double-Eye Spring, # PR626 will not be heavy enough for your trailer. It is only rated at 2,250 lbs.
When replacing springs on an axle you divide the axle carrying capacity in half to get the spring capacity. This means that you will need at least 3000 pound springs. When you measure your old springs, they will measure longer than the new spring due to wear.
Since you have a broken spring you may want to go with the Double-Eye Spring, # PR6. This i

- Which Leaf Springs for my 5x10 Trailer with a 3,500 Pound Axle
- There is a lot of variance in how much a spring will stretch. A trailer that carries a lighter load or is not used frequently will not have as much spring stretch. The springs you were looking at, part # PR626, are made for trailers with 4,500 pound axles. It might result in a bit rougher of a ride.
The double eye springs we carry for a 3,500 pound axle are 25-1/4 inch long. At six years of age, I can see the springs stretching 3/4 of an inch. We have two springs that would work for your, par

- Replacement Springs for a 2004 Coachman Cascade
- The eye to eye measurement needs to be taken when there is no load on the springs. The trailer needs to be jacked up so that the wheels are not touching and the springs are bearing no load. If they are measuring 26-1/8 with a load on them and they are nearly flat, I would imagine a 25-1/4 inch spring would be too long. Something like part # PR6 would probably be a more appropriate spring, but please measure the spring when you can get the trailer off the axle.
If the springs are almost flat,

- Will the Larger Capacity Leaf Springs # PR4 Fit Tandem Axle Trailer With 3,500 lb Axles
- If the measurements on your trailer match the 4-Leaf Double-Eye Spring, part # PR4B or part # PR4, they will bolt up to your trailer.
My contact at Redline informed me that the heavier 4-Leaf Double-Eye Spring, part # PR4 will work, but it will give you a rougher ride. Also the weakest link on the trailer will be the 3,500 lb axles when using the 4,800 lb leaf springs.
It is recommended to use the Leaf Springs For 3,500 lb Axles, part # PR4B for your trailer with 3,500 pound axles.

- How to Determine Which Leaf Springs to Order for Tandem Axle Camper with 3,500 Pound Axles
- When replacing the leaf springs on your camper you will need to match all of the dimensions and the spring capacity as closely as possible to the original spring.

See picture I have included that will show the measurements you will need to match to replace your leaf springs.
