Review of Redline Trailer Suspension APUBR-8


Today we're going to be reviewing part number APUBR-8. This is Redline's U-Bolt Kit for mounting 5,200-pound to 7,000-pound round trailer axles. It's going to attach the trailer to the leaf springs. It's going to include four 7-inch-long U-bolts. We get that measurement by measuring from the bottom of the cross member to the bottom of the U-bolt post. The threaded portion is going to measure 1 and 7/8ths of an inch.

Each bolt is going to give us a diameter of a half-inch. The distance that we have between the two posts is going to measure 3 inches. Each U-bolt is going to be identical, so they're all going to offer the same measurements. It's also going to come with two U-bolt plates for 1 and 3/4-inch or 2-inch springs. The overall dimensions of one of these plates is going to measure 5 and 3/8ths of an inch by 3 and 3/4 and again, both of those plates are going to be identical, and then it's going to come with the eight half-inch hex nuts that are needed to secure everything. Spring seats are required for mounting the axle to the leaf spring and those are going to be sold separately. This is designed to fit axle diameters of 3 inches, which is going to be your typical 5,200-pound to 7,000-pound trailer axle, with a spring width of 1 and 3/4-inch or 2-inch. That's going to do it for today's review of part number APUBR-8.
