Review of etrailer Trailer Leaf Spring Suspension - 3 Leaf Double Eye Spring 4000 lbs Axle - e57SR Video

If what you have now Chad is pretty flat at 26 inches then the best replacement size would be 25-1/4 inches like you mentioned. Since you wanted to increase the capacity you would want the part #e57SR which is for 4k trailer axles.

I am happy to try to help you find a bearing kit for your Bix Tex trailer. Unfortunately we are not able to recommend a bearing kit based off of just the axle capacity. One way to find out your bearing sizes would be to have a Bix Tex dealership…

Hey Jaime, yes you can replace your 25-1/4 inch 3,500 lb axle leaf springs with a 5k rated axle spring like the part #e44SR. This will increase the suspension's weight capacity and might make the ride quality a little rougher but it would fit…

Hey Kevin thanks for your question. There is not much downside to going with the 5,000 lb springs instead of the 3,500 lb. A higher rated spring may make the ride a bit more "chunky" at times, since the spring would not flex as easily.…

I'd recommend the 3-Leaf Double-Eye Spring for 4,000-lb Trailer Axles part #e57SR which measure 25-1/4" long and have a bit more capacity than your standard 3,500 lb spring so they won't wear out as fast. This means you must also replace…

Over time, any suspension components can fail and need to be replaced. Since you said a shackle broke now would be a good time to inspect all of the suspension components and replace any that show signs of damage or uneven wear. It is always best to…

If the leaf spring part #e57SR that you referenced matches up dimensionally to what your trailer has and has a capacity that is 400 lbs more than needed it would work just fine. Having a bit extra capacity for the leaf springs would not cause an…

You can replace your current springs with higher capacity springs, like #e57SR which are rated for 4,000 pound axles (2,000 pounds per spring), but it isn't going to increase the weight capacity of your trailer. You'll still be limited by the…

For all of our springs we list the unloaded length measured center eye to center eye straight across. Leaf springs can extend up to 1" when flexed. If you are looking to replace old leaf springs, you will want to jack up the trailer so that the…

To correctly measure a leaf spring, you'll want to jack the trailer up on jack stands so the axle is hanging freely, then measure directly across from the center of one spring eye to the other, as shown in the provided diagram. The height of the…

The problem seems to be mostly that your shackle straps are hitting the frame, and the reason for this is almost certainly because the 3-1/8" Shackle Strap #TRSL313 you are using are too long. The other possibility was the hangers being too…

Using the Shackle Bolt with Locknut for Double-Eye Springs - 3" Long, part #166081, indicates that your leaf springs are 1-3/4". If that is the case, the bushings you need have an inner diameter of 9/16" and an outer diameter of…
