Review of Universal Group Trailer Leaf Spring Suspension - Springs - SP-072275 Video

As you noted, the typically wiring colors for a 4-Way connector is white for ground, brown for tail/running, yellow for left stop/turn, and green for right stop/turn. The confusing part is that even though this is the typical way that the wiring is…

Thanks for the photo. You will not have any issue using the Dexter Heavy-Duty Suspension Kit for Tandem-Axle Trailers - 1-3/4" Wide Double-Eye Springs #K71-449-00 and moving the equalizer bolt down to the lower hole position. This will work…

In order to determine which replacement axles you need, I will need a few measurements. I will need hub face to hub face measurement, spring center to center dimension, inner and outer wheel bearing reference number, and the axle capacity. Take a…

There is no specific torque rating for shackle bolts. Basically for the middle bolt there should be enough free play in the shackles to allow them to move. Tightening the shackle bolts too much will squeeze the shackle straps against the leaf springs…

In order to determine the torque rating for the lug nuts on your trailer you will need to know check out the chart I attached that shows all of the torque specs for all the trailer lugs available based on stud size, wheel material and wheel size.

The closest we have to the 19-1/4" length is the 3-Leaf Double-Eye Spring #SP-072275. It is 18-5/16" from eye center to eye center on the double eye spring. I have included the rest of the measurements below so that you can compare with…

The leaf spring hanger positions are largely dependent on which exact equalizers, exact leaf springs, and exact shackle straps you will be using as the length of these components is then what makes up the hanger positions. That said, I would not be…

The 3-Leaf Double-Eye Spring #SP-072275 is the closest size we have at 18-5/16" to your 18.5" measurement. If your springs are used or have weight on them they will flatten out and as the spring flattens it will get longer. This spring in…

Each of the leaves of the Leaf Spring part #e64SR that you referenced are 1/2 inch thick. Since there is a total of 6 leaves the overall thickness is 3 inches. If you include the bolt that runs through all of the leaves the overall thickness is 3-3/4…

I do not recommend using a leaf spring spacer (lift block) on your trailer. The reason for this is because they can cause the trailer to become extremely bouncy and rough which is just going to put more stress on your suspension and wear out the…

You can mount trailer axles above or below the leaf springs. The difference is just the amount of ground clearance that the trailer would end up having. The biggest advantage with the spring below the axle (trailer will be lower) is that you would…

Correct, you will need to have a spring set installed on the axle tube to hold the leaf springs in place and prevent them from sliding back and forth. That said, although we do not have any spring seats specifically for a square tube axle you can use…
