etrailer Trailer Suspension - Leaf Spring Suspension - AP233 Review Video

Yes, the etrailer equzlizer suspension kit part #AP233 that you referenced can replace a straight equalizer like you have now. The one side of the leaf spring would hang a little lower but it shouldn't be a problem.

The standard diameter for trailer leaf spring bolts is 9/16 inch which is why the part #E4139 and all similar options have this hole size. We don't have anything with a smaller diameter but my guess is what you have is actually 9/16 inch.

In the past we've found that the trailers that have 31 inch wheelbases use the equalizer #TREQ104 so based on that the correct kit you'd need would be the part #AP233.

The torque requirements for leaf spring u-bolts depend on the diameter of the u-bolts that are being used. If the gross weight of your tandem axle trailer is 7,000 lbs, then you likely have two 3,500 lb axles. Typically 1/2 inch diameter u-bolts are…

When it comes to determining which equalizers are needed for your EZ Loader boat trailer, you will need to get some measurements. I have included a diagram with information as to what measurements are needed. I have also included a link to our…

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…

Leaf spring hangers come in different heights to provide more or less clearance between the trailer body and the suspension. Manufacturers determine the best spacing for the axles and sizes of the hangers, leaf springs, equalizers, and shackle straps…

Hey Rob, the bolts that come with the equalizer kit part #AP233 that you referenced are Grade 5.

I recommend going with an over-under kit. For a 2-3/8 inch diameter round axle use #K71-384-00 and for a 3-inch diameter round axle use #K71-385-00. This will allow you to move your springs to the top of the axle. These kits can only be used with…

Yes, it is a good idea to go ahead and add grease when installing the Suspension Kit for Tandem-Axle Trailers - 1-3/4" Wide Double Eye Springs - 2-1/4" Links #AP233. You don't want to use fat though, just go ahead and use the LubriMatic…

The equalizers of the part #AP233 have bushings in them already. The leaf springs you would use these with would already have bushings as well most likely. Typically people do not need to buy bushings with this kit or with this kit plus leaf…

You can use leaf springs that are rated higher than the axle without any issues as long as they measure the correct measurement for your trailer. For example the 6-leaf double eye spring for 7,000 lb axles part #e64SR measures 24-7/8" eye to…
