Although we do not have spacer blocks of that dimension we have an option for you that will allow you to lift your trailer with what is called an over/under conversion kit.

This moves your trailer's leaf springs to the top of your axle and lifts your trailer approximately the same amount as your axle's diameter plus the height of the leaf spring pack (please keep in mind this conversion kit is for use with double-eye springs only). The accompanying photo a customer sent in shows the end result of using this kit.

If you had a 2-3/8" round axle you would need Dexter Trailer Springs Over-Under Conversion Kit # K71-384-00 or if you had a 3" round axle you would need Dexter Trailer Springs Over-Under Conversion Kit # K71-385-00.

I've added links to video reviews of both kits for you to check out.

I have a pull trailer that is riding to low for me Id like to lift it 3 or 4. The U bolts are 6long and about 3 3/4 apart. The spring shackle is 2W on what looks like a 2750 lb axle that looks like its 3 in dia. What do you have in the way of lift blocks with U bolts? Thanks

We don't have any standard lift blocks for leaf spring suspension setups, but if your axle has a 3" diameter you could use the Over-Under Conversion Kit # K71-385-00. Assuming your leaf springs are currently beneath the axle, this would lift up the trailer by the combined height of the axle and leaf spring stack.

Mine are on top of the axle.

If the springs are already on top of the axle the best way to lift the trailer up would be to cut off your existing hangers and weld on longer ones in their place. I linked our selection of hangers below that you can look through.

To change the 4.80x12 tires on your Karavan 5' x 8' utility trailer to ST175/80D13 tires you will need need to have 5-6" clearance between the top of the tire to the bottom of the fender, and 2-3" between the inside of the tire to…

"Flipping the axle" is just an expression that is used for an over/under kit but nothing happens to the axle so there is no need for a different size of wheel and tire than you currently have. What these kits actually do is move the…

Hello Tyler, thanks for reaching out. The 2,200 lb axles are generally a 1-3/4" tube diameter and I am sorry to say we do not offer an over-under kit for this. At this time we only offer kits for 2-3/8" diameter #K71-384-00 and 3"…

The Dexter Trailer Springs Over-Under Conversion Kit like part #K71-384-00 does not require welding. That said, it is recommended to tack the spring seats to the axle but this is super easy to do even for someone with no prior welding experience. It…

Answer 5

Yes, this could be caused by worn out leaf springs on your trailer. Sometimes you'll see this caused by using shackles that are too long, but in this case it's probably safe to assume that this is being caused by worn out leaf springs. If you…

Answer 6

The best thing to do in this situation, because you have such little clearance, even with an empty trailer, is to replace your equalizers with taller ones. To pick out a compatible replacement equalizer you'll need to measure the distance between…

Answer 7

It does look like you have shackle straps that are to long and possibly worn out bushings. You can replace your shackles with the 2-1/4" Shackle #LC122487. You will need 8 of these for the entire trailer. I would recommend pulling a couple of…

Answer 8

The problem seems to be mostly that your shackle straps are hitting the frame, and the reason for this is almost certainly because the 3-1/8" Shackle Strap #TRSL313 you are using are too long. The other possibility was the hangers being too…

Answer 9

Trailer manufacturers don't usually keep a record of parts like these that they install at the factory, so I cannot be sure as to the exact length of the shackle strap that would have come originally on your trailer. With this in mind, a 3-1/8…

Answer 10

The first and easiest thing you should check is that the trailer is being towed level. If the trailer is nose high or low that can cause the equalizers to not sit level. You will need to select the correct rise/drop ball mount so that the trailer…

Answer 11

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 12

It's not a stupid question, it's a perfectly logical one but you should not flip the Dexter Trailer Axle Beam with 4" Drop E-Z Lube Spindles #7685269 to get rise as this was not the intended design as it is an underslung axle with spring…
