Comprehensive Review: U-Bolt Kit for Mounting 3,500-lb, Round Trailer Axles Video

Andy, while I do like your Axle #e95SR and U-Bolt Kit #CE23002 selection of which you will need 2 of each I do have another recommendation for the suspension kit. The Tandem-Axle Trailer Hanger Kit #APT3 you found has longer equalizers designed for a…

Hello Jason. Generally, we do want the shackle size to be an exact match, but a difference of 3/8" should not be an issue. There is a bit of tolerance when replacing shackles but anything less than 1/2" is considered acceptable. The MORryde…

Hey Calvin, For a suspension upgrade kit on your Arctic Wolf 5th wheel trailer what you need to do is measure the length of your shackle straps from center to center to get the right length. Based on those lengths you will need either of the…

Hey Todd, The 500lb increase in capacity to the 4-Leaf Double-Eye Spring #e22YR will definitely work and would probably give you a bit sturdier of a ride because the springs won't compress as easily. Going too stiff can cause problems though so…

First, thank you so much for providing all the axle information on your 2007 Fleetwood Redline 33. The 4-Leaf Double-Eye Spring #e47SR is our closest match to the Lippert 702096 leaf springs that came on your trailer. You will want to order 4 of…

Hi Americo, thanks for the question and you do need to stick with the same size 2-1/4 inch shackle straps that are in the MORryde Suspension Upgrade Kit for Tandem Axle Trailers #MR46ZR. Going with longer shackle straps can negatively affect the…

You'll need the CE Smith U-Bolt Kit #CE23002, 9/16" Bolts like part #126B2 and then one of the following leaf spring sizes: - 23-1/8" Long #e59SR - 25-1/8" Long #e68SR - 27" Long #e97SR To get the correct leaf spring length…

When replacing shackle straps they should be the same length as the ones that were previously on your tandem axle trailer (if possible); replacing them with longer straps will result in additional play in your trailer suspension which could lead to…

Yes the 4,000-lb leaf spring is compatible with a 3,500-lb axle. There are a couple of important measurements. Spacing from eye to eye on the spring when unloaded with no weight on the axle. Inner eye diameter of the spring roll Spring width from…

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…

You can use leaf springs that are rated higher than the axle without any issues as long as they measure the correct measurement for your trailer. For example the 6-leaf double eye spring for 7,000 lb axles part #e64SR measures 24-7/8" eye to…

There should be enough free play in the shackles to allow them to move. There is no specific torque rating for shackle bolts. The first thing you should make sure of is that the bolts you use are long enough so that when installed you will have at…
