Recommend Hangers, Shackle Straps, and Bolts for Equa-Flex Cushioned Equalizers # LC279688

Question

Question:

I would like to install these Equa Flex equalizers on a trailer rebuild I am doing and am wondering what length axle hangars I should get for the front, center, and rear to make the geometry correct as there are none currently installed on the trailer. Also what length shackles should I use? I would be installing these on a set of 6000 lb axles with 1.75” x 25.25” double eye leaf springs. I was also looking to get some insight as to whether I can use a wet bolt setup with these components as well? Thank you.

For a center hanger you will want something that isn't too tall because equalizers # LC279688 are quite tall compared to regular equalizers. Hanger # 115918 is what I would go with.

The front and rear hangers would need to be taller than the center so I recommend # E4139. Then for shackle straps I recommend # TRSL313. This should get you right about level.

So you will need:

2 of hanger # 115918
4 of hanger # E4139
8 of shackle strap # TRSL313
14 of wet bolt and nut # 126B2

The Equa-Flex Cushioned Equalizers # LC279688 with bronze bushings can use wet bolts such as # 126B2.

The trailer will have a plate or sticker on it that will list the VIN number. The weight rating of the axle should be listed on that same plate or sticker. Also, the axle could have a tag or plate on it that will list the weight capacity. You can…

The #APT9 kit will work well for you. Since the equalizers are only 1/4 inch shorter than your current ones, the shackle straps should provide you with enough play to be able to place the new hangers in the same position as your current hangers. If…

Answer 5

In general shackle bolts turning from use over time does not considerably wear out components. As long as the bolts are greased normally the movement from standard use would not cause them to wear out. The tension of the bolt and nut is loose enough…

The front (or rear) axle definitely shouldn't be wandering around like what you described on your friend's tandem axle trailer. I recommend making sure that the slipper springs are securely attached to the center and front/rear hangers and…

Answer 9

When replacing shackle straps they should be the same length as the ones that were previously on your tandem axle trailer; replacing them with longer straps will result in additional play in your trailer suspension which could lead to additional wear…

Answer 10

To slightly lower your trailer that has had an "axle flip" kit installed you would want to use slightly shorter shackle straps, not longer ones. Shorter shackles will let the axle rest closer to the trailer frame, which lowers the trailer…

Answer 11

The shackles on your equalizers should be pointing up when the trailer is under its weight on the ground, and will only point down like you mentioned when the trailer is in the air and the axles are off the ground. It is pretty common for one side of…

Answer 12

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…
