Replacement for 26.25 Slipper Leaf Spring for 700 lb Trailer

Question

Question:

My current leaf spring is 26 1/4inch and only holds 700lbs. Will this work as a replacement? The current springs are 1 3/4inch wide. Also how many inches long is it from the end of the arch to the end of the flat part? And what about from the center of the bushing hold to the middle of the arch on the other end? Thanks

For a 26-1/4 inch long slipper spring that is 1-3/4 inches wide we have a spring that is going to be way overkill with capacity as the part # e33SR. This has a 4,300 lb capacity.

The best option would be the part # SP-177275 with you moving your current hangers most likely as it is 24-5/8 inches long overall and 22-11/16 inches long where it mounts to hangers.

To switch to a Double Eye Spring #e48SR you would need to also change out your Rear Hanger #30-20 since you will be adding Shackles #K71-358-00. This is required since the rear hanger has to be 1-3/4" wide on the outer versus at least…

For the spring eye you would use the Spring-Eye Bolt with Locknut for Slipper Springs - 3-1/2" Long #166079, but slipper springs don't have the second spring eye, so a bolt is not used on the back end. You can also use a wet bolt like…

Answer 5

It sounds like you already have done the correct center of one eye to the center of the other eye measurement. If your measurement is slightly off, sometimes the leaf spring may still work as leaf springs do expand by as much as 3/4-inch over time.…

I can help you determine how to figure out the right replacement slipper springs, though I'm not 100% certain what you mean by "where can I find how much space or clearance is required." I think you are asking if there is a standard…

The bushings of the 4-Leaf Spring part #e33SR have a 9/16 hole diameter. If you are looking for a replacement bushing you would want the part #TRBU11561. This bushing has a 9/16 inner diameter and an outer diameter of 1.02 inches.

Answer 10

When picking out a leaf spring you really want to base it on the capacity of the axle and the length more so than the amount of leafs in the spring pack. If you can get me the axle capacity of your trailer and how long you need I can get you the best…

Answer 11

As they wear, leaf springs tend to flatten out. The first step is to get the correct length of the existing springs. In order to do that, you'll need to put the trailer up on jack stands and measure them (center eye to center of the slipper) with…

Answer 12

A bushing is not required for the c-hook end (sometimes called an open eye end) of a slipper spring like the 4-Leaf Slipper Spring w/ Open Eye End #e33SR. The closed eye of this spring does have a bushing included; I have added a link to a video…
