Recommended Axle Flip Kit for a Tandem Axle Trailer

Question

Question:

I saw a question Jeffery L responded to in regards to the over-under kit for trailers. We just replaced both axels on our cargo trailer with a drop axel. The trailer is very low and we go off-road, therefore, the trailer will drag when loaded. So, my question is if we flip the axles so the leaf springs are on top, can we just buy the spring seat or do we need to purchase the entire kit? In other words, since we are just placing the springs on top instead of under, we should have all the other parts or do these kits have specific parts that are not normally used. Thank you in advance...

To flip the axles on your trailer you will need the Dexter Trailer Springs Over-Under Conversion Kit item # K71-384-00 if you have 2-3/8" diameter axles. Or item # K71-385-00 if you have 3" diameter axles.

The axle flip kits raise your trailer height in correlation to your axle size. The kits come with only the parts needed. You won't have anything spare you are paying for. You will need one kit for each axle. I have linked an installation video below so you can see the installation process.

Answer 5

Since you have a tandem axle trailer rated for 10,500lbs the 6-Leaf Double-Eye Spring for 5,300-lb Trailer Axles #e76SR are going to be the closest leaf springs we have to that weight capacity. These springs measure 24-7/8" from center of eye to…

Hey Chad this is a great question. So the MORryde ALLTREK part #MR89DR does offer additional vertical suspension but it does sit a little taller than the equalizers it replaces so you wouldn't have to worry about your tires hitting fenders or…

Hey Jaime, yes you can replace your 25-1/4 inch 3,500 lb axle leaf springs with a 5k rated axle spring like the part #e44SR. This will increase the suspension's weight capacity and might make the ride quality a little rougher but it would fit and…

Answer 8

Yes, the spring width would matter when using the Dexter Over Under kit part #K71-384-00 that you referenced. If you check out the picture I attached you'll see that if the spring was too wide the u-bolt holes of the plate wouldn't fit around…

Answer 9

Hey Scott, so the braking and hub components of a Dexter 3,500 lb axle made in 1999 would be the same as what's currently used so those components would transfer over. So a bare axle like the part #T3584F-EZ-8974 would work for you but you'd…
