Review of Dexter Trailer Suspension APT5

Toay we'll be reviewing part number APT-5, this is Dexter's tandem axle trailer hanger kit for double wide springs. It's going to attach four leaf springs, which are going to be sold separately, to your trailer frame. You can use the table on this product's product page to help determine the hanger location based on the type of leaf springs that your trailer has. It's going to achieve four and one half or five inch clearance between the trailer frame and the axle, depending on the axle size. So what you see here is what you're going to get: you're going to get six three and one quarter inch tall hangers. That height measurement is taken from the center of this hole location here at the base to the top of the hanger. So it's going to measure three and one quarter inch in height.

You're also going to get two seven and three quarter inch long curved equalizers. All the holes are going to have the same diameter, that's going to measure a diameter of 9/16th's of an inch. The length on those equalizers are measured center on center between these two hole locations, so that's where we're going to get the seven and three quarter inch. It's also going to come with eight two and five eighth inch long shackle straps. Again, that two and five eighth measurement is measured from center of one hole to the center of the other. You're going to get 14 three inch long by 9/16th inch diameter shock-able bolts, as well as 16 nuts.

This is designed for use on trailers with tandem 2,000 pound to 7,000 pound axles, and it does not include the components for mounting the axle to the springs. That's going to do it for our review of part number APT-5, this is the tandem axle trailer hanger kit for double wide springs. .

Reply from Jon G.

The Tandem-Axle Trailer Hanger Kit # APT5 does use locknuts. There actually isn't a torque requirement when it comes to suspension bolts. You want to tighten them down so that the knurls (grooves at the head of the bolt) are hidden inside the sleeve on the leaf spring and then enough so that the bolt is at least showing through the locknut. Essentially you want to tighten the locknut down hand tight and then back it off about a 1/4 turn so that the suspension has some freedom to move when needed.
