Changing Spring Hangers To Raise Or Lower A Trailer

Question

Question:

If I add different size spring hangers to my travel trailer, does the length you increase/ decrease correspond to actual lift/lower height? Example If I add 2inch longer hangers all around will my trailer actually ride 2inch higher after I adjust the hitch? I dont want the 5-6inch of flipping the springs to the top of the axle. Thanks in advance

Yes. If you change no other components, the hanger length increase should directly correspond to the lift of the trailer. So, if you use a tandem axle kit like the Tandem-Axle Trailer Hangers for 1-3/4" Wide Double-Eye Springs - 3-1/4" Tall Front # H248, and each hanger is 1-1/2 inches longer than your current corresponding hangers, you will lift your trailer by 1-1/2 inches. This would work the same way for lowering a trailer.

Can I flip my shackles to gain a little tire clearance on my tandem axle travel trailer?

Flipping your shackles won't be the solution you are seeking. You instead will want to flip your axles using an over-under kit like # K71-384-00 for 3,500 lb axles or # K71-385-00 for 3 inch diameter axles (typically 4,200 to 6,000 lb capacity). This moves the leaf springs from under the axle to putting the spring seats on top of the axles gaining you the 2-3/8 inch or 3 inch diameter of your axle plus the height of your leaf spring stack. This will give you the tire clearance you are seeking on your travel trailer and requires no welding or changing out other components.

A lot of it depends on the length of the springs and equalizers that are used. When using Leaf Springs #e64SR with the #AP233 Equalizer Kit and the #H248 Hanger Kit, there should be 29-1/2" between the front and center hangers and 29-1/2"…

Hello Francis. Thanks for sending in the pictures. With the axle being 3" diameter tells me that they are 5,200-7,000 lbs. I have a solution for you, but you probably aren't going to get too excited about it. Your best bet is to replace…

Hi Travis; those look pretty flat so I don't think 26" would do it either. The 25-1/4" long #EM86RB you ordered will be a better fit. Completely flat these would have a similar measurement at just over 26" which is in line with…

Hey Darrel, we actually have exactly what you are looking for with the part #TRU52FR which is for a 7k axle and is 25-1/4 inch from eye to eye. This is also a 6 leaf spring as well. The spring you referenced would be too short.

We do have a couple of bolt-on spring hangers #CE14017G and #CE14016G but they are designed for slipper springs and not double-eye springs like #e77SR. Its not likely that professional welder would charge that much. You might be able to find one…

The angle of the shackle straps is not a precise measurement but you will want them to be around 45 degrees. The diagram may look different but staying around 45 degrees is where you will want to be. I have included a link to our FAQ article on…

Hey Henry, that's a great question but the answer is that it depends...it depends on if your axle is above the leaf spring or below it. If your axle is above the leaf spring it wouldn't affect the trailer height. If below it would raise it.…
