I completely understand your troubles and confusion with leaf springs. First do remember there are different types of spring steels so the thickness of the leaves is not always the best way to judge the weight capacity for the leaf springs. So while you would think a 3/8" thick leaf would be stronger than leaf springs which use 5/16" thick springs that is not always the case depending on the type of spring steel used. With as quickly as your new springs failed it makes me think they either... view full answer...
The tires on a trailer must all have the same load range rating as each load range requires a different psi rating. If you were to fill them all to the same psi then the weight capacity of said tire would be compromised. Therefore, you are going to need to choose a new tires that matches the load range of all other tires on the trailer. If you were to go against this then you would be at risk of a blowout due to increased heat buildup.
If you can let me know what size tires you have on... view full answer...
A 5200 lb axle is actually a 6000 lb axle that's been de-rated by using a different outer bearing.
The proper replacement leaf spring will depend on how long the original springs are. Because leaf springs flatten out and become longer as they wear out. To choose the proper replacement, you'll need to know if you have a double eye or a slipper spring. You'll also want to measure the springs by jacking the trailer so that the axles hang free. You'd then measure the center spring eye to center... view full answer...
The # e47SR leaf springs you'd looked at are designed for 6K capacity axles.
In order to get an accurate measurement of your leaf springs, you'll need to put the 5th wheel up on jack stands so the axles hang freely. Then measure the center eye to center eye length of the existing springs. This is very important because leaf springs tend to flatten out over time. If you have tandem 6K axles, it's very possible that your leaf springs have flattened out by 5/8 of an inch.
To confirm, you'll... view full answer...
