The load or hitch height would not affect the front spring eye. For it to come unwound or loose its rounded shape there has to be some kind of rearward force pulling it out of round. This would shift the front axle effecting the equalizers and the tire spacing.

The best bet here is to replace that front set of slipper spring and inspect it regularly to determine when the damage has occurred. We carry a good selection of slipper springs like the 7-Leaf Slipper Spring w/ Hook End for 8,000-lb Trailer Axles 26-5/8" Long part # e37SR which may be the one you need.

Yes, leaf springs must be replaced in pairs which is why one side left go and then the other shortly after. In regards to the stent you get on a full set of leaf springs, there are really a ton of variables present here so it is hard to predict.…

Hi Todd, To go with trailer leaf springs that are slightly stiffer than the 4,400 lb rating of your axle you can go with 4,500 lb springs or 5,000 lb springs. The right one is going to depend on the length of your current springs though, as…

Hi Travis; those look pretty flat so I don't think 26" would do it either. The 25-1/4" long #EM86RB you ordered will be a better fit. Completely flat these would have a similar measurement at just over 26" which is in line with…
