Solution for Gaining Axle and Tire Clearance on Triple Axle Enclosed Trailer
Question:
I have a triple axle 35 foot bumper pull enclosed trailer that the top of tires are very close to the inner fender wells. The tires do rub and get ruined. The axles are 7k with leaf springs. The frame is bent where axles come up and hit the frame. The hangers are 3 from top to center of hole, I feel the trailer builder installed too short hangers. What should the measurements be for new hangers? how much space do I need from top of tire to fender? how far should axle be from I-beam frame so it wont hit? Thank-you

Expert Reply:
Typically you want at least 3" of clearance from the axle to the trailer frame. 3" of clearance is also recommended on the top of the tire. If this was made by a reputable trailer manufacturer the hanger size is probably not off, but it is possible. It may be that your suspension is worn out. I would check out the leaf springs to make sure they aren't flat.
If you're going to install new hangers you will need to choose based on the spring style and width. If you have double-eye leaf springs they're all the same width. Slipper springs vary so you would need to measure the width. Once you have this information you can choose hangers that will give you the additional clearance.
Alternatively, you could flip the axles to gain the additional lift/clearance you need. The Dexter Trailer Springs Over-Under Conversion Kit # K71-385-00 would allow you to put the axles under the leaf springs. This would raise the trailer the width of the axle (3") plus the height of the leaf spring stack. You would need one for each axle.
If your axles are already below the leaf springs you could use the Correct Track # RR55QX instead. This would allow you to raise the trailer 2-1/4" while also aligning the axles.
