Hey Dennis, thanks for reaching out! The 4-Leaf Double-Eye Spring #DX23CR has a 3" drop from center eye to middle of the leaf spring (see attached photo). For a single axle setup I recommend the Hanger Kit #APS4, and for a tandem axle setup I…

The clips on the #e77SR leaf springs are designed to be forward of the axle due to braking axle wrap (twisting). The straps/clips aren't super strong to prevent this but they're still there. If the strap comes off or the leaves come apart it…

We definitely don't have any of that and I imagine you are going to have a heck of a time trying to find anything that will work due to the age. By far the best bet is a new axle and hubs, which doesn't have to be super expensive. To find the…

Axle dimensions are fairly standardized. Those we sell are offered in 4 lengths, 57-1/2-inch, 60-inch, 72-inch and 89-inch. We also have axles-less trailer suspensions from Timbren that bolt on to the trailer frame and eliminate the leaf spring…

Yes the hangers from Hanger Kit #APT5 must be welded to your trailer's frame by a qualified welder, preferably one with experience on trailers. As for the load capacity of the trailer, that will depend on the part of the trailer with the lowest…
