How to Determine Correct Over-Under Kit For 5,200 lb Axles

Question:

I have an Evergreen reactor 25fqs with 5700k axles. Does the standard flip kit work on this? And do I need anything else for the flip kit install or just two kits? How much lift will it be? Is the factory 2 step enough after installing?

Did you mean 5,200 lb axles by chance? I only ask because I'm not aware of 5,700 lb axles, but either way the Dexter Over-Under Conversion Kits will work with your axles so long as it is either 2-3/8 inches or 3 inches in diameter and uses double-eye leaf springs (as opposed to slipper springs). Since a 2-3/8 inch axle is normally just for 3,500 lb axles, it is likely yours is 3 inches in diameter, but you will need to verify that to be sure. Here is what you will need, depending on your axle size:

- 3 Inch Diameter Axle: Dexter Trailer Springs Over-Under Conversion Kit # K71-385-00

- 2-3/8 Inch Diameter Axle: Dexter Trailer Springs Over-Under Conversion Kit # K71-384-00

Nothing else would be needed, and for tandem axles you would need two kits. In regards to height, these kits will lift your trailer approximately the same amount as your axle's diameter plus the height of the leaf spring pack. As for the steps, these kits won't raise the trailer to the point where new steps are needed.
