Review of Redline Trailer Suspension APS4


Today we're going to take a look at the Single Axle Trailer Hanger Kit for double eye springs. Now this leaf spring mounting kit includes the 3 1/4" tall front hangers, the 1 1/4" tall rear hangings, and all the necessary hardware for installation. This will attach two leaf springs to your trailer frame. We sell the leaf springs separately on our website. Basically to determine the hanger location on your trailer, we do have a table at the bottom of this product page that will show you measurements that are required based on the types of leaf springs that you use. This part will achieve 5" or 5 1/2" clearance between your trailer frame and your axle, depending on your axle size you use, and includes all the parts showing here. It includes the two 3 1/4" tall front hangers.

Now when they say 3 1/4" what they're measuring is from the center of that hole to the top here. If we put the ruler on, you can see there's your 3 1/4" measurement. The two 1 1/4" tall rear hangers, and same way from the center of the hole to the top. There's your 1 1/4" measurement. The shackle straps is four 3 1/8" long shackle straps.

The shackle straps are measured from center to center. There's your 3 1/8". It comes with the hardware, the six 3" long by 9/16 shackle bolts, and the six 9/16 diameter lock nuts. Now this part is designed for use on trailers with 2,000 pound to 7,000 pound axles, and it does not include components for mounting your axle to the springs. That should do it for the review on the Single Axle Trailer Hanger Kit for double eye springs.
