In order to determine the correct replacement shackle links for your Keystone 5th Wheel Trailer, you will want to measure both the length and hole diameter on your existing parts. Unfortunately, trailer manufacturers do not typically keep record of smaller parts like suspension components that were installed at the factory. Finding a replacement that matches the dimensions on your current shackle is the best and most accurate method.

I have attached a link that will take you to our available selection of trailer suspension parts, such as the shackle links, equalizers, u-bolts and bushings that you can look through.

While changing the length of shackle straps isn't an ideal way to change the ride height of a trailer. If you were to shorten the shackle straps the trailer would sit slightly taller. This isn't ideal as the leaf spring wouldn't sit level…

Answer 7

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…

In order to retain the same suspension geometry, when you replace shackles you should use the same length replacements. Going with a shackle that is too short will not allow enough articulation in the suspension, and cause a very rough ride. Using a…
