Review of etrailer Trailer Leaf Spring Suspension - Tandem Axle Suspension Kit - e99ZR Video

Thank you for providing the specs for the suspension components that you already have. Correct hanger spacing really depends on the components being used such as springs, hangers and equalizers. Most of the hanger spacing dimensions that we have are…

You will have to do some measuring. Take a look at our Double-Eye Trailer Suspension article (see link). I have also linked a picture of a shackle link showing where to measure. Measurements for replacement 1) Measure current shackle from center of…

Yes we do have a version of the equalizer kit part #e99ZR that has shorter shackle straps with the part #AP233 which has 2-1/4 inch length shackles instead.

No problem! It's not all going to be as a kit but you'll need the following part's and quantities: (2) Equalizers #TREQE1 (8) Shackle Straps #TRSL313 (14) Bolts #166079

I am happy to help! Starting with the two holes in the shorter hangers included in the Tandem-Axle Trailer Hanger Kit for Double-Eye Springs - 2-1/2" Front/Rear, 4-1/2" Center #APT8 you were looking at. Those holes are not for bolting but…

The 60/40 axle placement formula is a great starting point and does take into account the tongue of the trailer from where the trailer sits on the hitch ball. Please keep in mind that this is a very basic formula or estimate for axle placement. For a…

It depends on the leaf springs you are using. Basically you will need to mock it all up before permanently installing anything on the trailer. Generally speaking the distance between hangers would likely be 24-3/4 inches on center to 29-1/2 inches on…

Grease seal set #RG06-050 is what you will need. These are double lip seals, just like what you have (the spring indicates that) and the dimensions are all the same including the 1/2 inch width.
