Where to Place Tandem Axle Slipper Springs on Trailer being Built
Question:
Im building a 24k with triple 3.5inch 8K under-sprung axles with 28inch slipper springs. the equalizers are 11.5 long, Mounts are 3.75 tall front spting is 4.5 and rear is 5. How can I figure out where to mount them on my 16+4 trailer. Also does the slip go towards the rear on all three in this case? Thank you

The slipper side of slipper leaf springs need to face the rear of the trailer.
To determine the location for the front and rear hangers on your tandem axle trailer you will first need to make sure that you have the correct center point for your equalizer hanger.
The center point of your equalizer hanger needs to be located where you will have 60 percent of the frame of the trailer in front of the center of the equalizer hanger and 40 percent behind the center of the equalizer hanger. For example, if the trailers frames length is 18 feet, then the center-line location for the equalizer hanger will be 10.8 feet from the front of the trailer and 7.2 feet from the back.
This is where to start with when picking out axle locations for a tandem axle trailer. You will need to determine the tongue weight of the trailer and then check out the picture I attached if the tongue weight is anything other than 10 percent of the total trailer weight.
