How much do springs actually flex? Given correct weight is on the axles rating. I want to install my axles above the springs but they are within a few inches of the frame. How much clearance is needed between axle and frame?

We usually tell people to look for about 3 inches of clearance to account for the total travel capabilities of trailer suspension. If you have less than 3 inches you might be able to compensate by using slightly longer shackle straps. I have included a link to the shackle straps we carry.

Answer 1

The amount of leaves won't make a huge difference on whether they will flatten out or not as what really matters is the capacity of the spring relative to the axle and trailer weight. I would go with at least ta 4,400 lb leaf spring or…

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…

The fact your outer bearing fits on a .75 diameter spindle means we aren't going to have a standard bearing kit to fit since that's not a standard dimension. Can you get me the C dimension as well? It could be that you need the part #LM67048…

Answer 5

From the measurements you gave me, it sounds like you have an Agricultural Spindle like #TRU54FR that uses #LM67048 Inner bearing and #LM11949 Outer bearing. For a hub assembly with a 4 on 5 bolt pattern #AH15450ECOMP will work and the bearings, seal…

It's hard to see in your picture but is the hanger open on the one side which allows the spring to slide out to the side? It shouldn't be open like that. If you need a replacement hanger we have the #115706S for if you have a 1-3/4 inch wide…

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…

I looked up the LoadRite parts and they have torsion axles and traditional spring axles. If you have a trailer that has the springs centered at 58 inches on center and is 1-1/2 inches square, then the axle is a 2,000 lb axle and you would use the…

Without replacing the wheels on your trailer the Kenda Karrier S-Trail ST145/R12 Radial Trailer Tire #AM10130 will give you a slightly larger tire. Your 4.80-12 tire is 4.9" wide and 20.9" tall. The ST145/R12 is 5.7" wide and…
