Question:
Lift kit for a single axle travel trailer with a Dexter 479845 axle
asked by: Bob M

Hi Bob; it looks like that is a Dexter 4k axle with leaf springs and it came in the underslung configuration. For a lift kit you can use an axle flip kit. This will raise the trailer by the diameter of the axle plus the height of the leaf spring stack. 4k axles can vary in diameter depending on what they're based on so you will need to check before picking out a kit. If it is 2-3/8" you can use the # K71-384-00 and for 3" # K71-385-00.
If your leaf springs are already on top of your axle, or you find you have a different diameter, let me know in the comments below.

Yes, but I decided not to raise it. I do plan on purchasing new brake assembly and wheel Bearings next year. Thank you!!
