Review of etrailer 4 Leaf Double Eye Spring - e97SR Video

The first thing I would check on your trailer is the capacity of the springs. You need to be sure the spring capacity is rated at 1/2 the axle capacity. That way 2 springs equal the capacity of the trailer axle for proper fit. Check the arch of the…

Is the trailer sitting nose high or low? If the trailer isn't sitting perfectly level that is a typical cause for the shackle straps to flip upside down. Or if they are too short for the application that could cause a problem. I attached a link…

If the shackle straps are within a 1/2" of what you normally had, say the 2-5/8" #115052 to 3-1/8" #TRSL313, you should be okay to install them. Just make sure that all of your shackle straps match though. If you are using the longer…

When replacing shackle straps they should be the same length as the ones that were previously on your tandem axle trailer; replacing them with longer straps will result in additional play in your trailer suspension which could lead to additional wear…

If your trailer has torsion axles, no worries but it it's a leaf spring suspension you really should have equalizers. Without the equalizer, the trailer will have a rougher ride and the weight won't be balanced across both axles when going…

I would need to know the axle capacities to be sure but I can venture an educated guess. The only tandem axle double-eye leaf spring hanger kit we have that includes 8 inch equalizers is #APT1. With this kit, the center of the forward hanger to the…

I do not recommend using a leaf spring spacer (lift block) on your trailer. The reason for this is because they can cause the trailer to become extremely bouncy and rough which is just going to put more stress on your suspension and wear out the…

What I recommend, if the trailer has round axles, is an over-under conversion kit. For 3 inch round axles use #K71-385-00 and for 2-3/8 inch round axles use #K71-384-00. This of course will only work if the leaf springs are mounted to the bottom of…

The 2x2 inch square axle is likely 3,500 lbs or less capacity. I would need more spindle dimensions or bearing numbers to assist. If you pull a hub and measure at the spindle where the bearings and seal ride using the digital caliper like #PTW80157 I…

Looks like you found the chart that Jeff D made that shows common axle capacities based on diameter: Typical Axle Diameters Based on Axle Capacity - 1,000-lb - 2,000-lb Axles: 1-1/2 inch - 1-3/4 inch diameter - 3,500-lb Axles: 2-3/8 inch diameter -…

You can mount trailer axles above or below the leaf springs. The difference is just the amount of ground clearance that the trailer would end up having. The biggest advantage with the spring below the axle (trailer will be lower) is that you would…

It is imperative you check your local laws for lighting requirements in regards to your specific trailer, though I can tell you you no matter what you'll need stop lights, tail lights, turn signals and reflectors. There are other factors,…
