Features to know about

Stops Bracket Wear Before It Starts: Fluted Shank Holds Steady

When a suspension bolt spins inside the hanger, it chews up the bracket and shortens its life. This 9/16" diameter shackle bolt fixes that with a fluted shank that locks in place so it won’t turn. The result is a snug fit that keeps the hanger round and solid mile after mile.

Keeps Your Setup Secure: Locknut Holds the Bolt Tight

You don’t want anything working loose under load. Each 3-1/2" long bolt comes with a matching locknut that keeps tension on the joint and holds the leaf spring where it belongs. It prevents unwanted movement and helps the suspension stay quiet and consistent.

Built for Routine Suspension Fixes: Mounts the Leaf Spring Right

This bolt is made for attaching a slipper spring to its hanger—one of the most common trailer suspension repairs. It’s a direct, no-guesswork replacement that restores proper function and alignment so the trailer tracks true again.

Simple, Complete Pair for DIY Work: Sold Two at a Time

When you’re replacing worn hardware, it makes sense to refresh both sides together. These bolts come in a matched pair, ready to drop in with the right 18-thread pattern for the included locknuts. It’s a clean, straightforward fix that brings the suspension back into spec.

Video Transcript for Review of CE Smith Trailer Suspension Parts - Shackle Bolts - CES25QR

Hello, everybody This is Jeff at etrailer.com. Today we're gonna take a look at the CE Smith 3 1/2 Inch Long Shackle Bolt with the Lock Nuts for a quantity of two. Now these are 9/16 diameter shackle bolts. These are used to mount your leaf spring to the spring hanger bracket or the equalizers. It is a fluted shank right here that keeps the bolt from turning in the bracket and wearing the bracket out. It is a grade 5 steel bolt.

It is for a quantity of two, and it does include the lock nuts to secure the bolt in place. A few specs on this again. We mentioned diameter 9/16 inch. The length, which is always measured from under the bolt head, is right at 3 1/2 inches long, and the threads is 18 threads per inch. But that's gonna do it for a look at the CE Smith 3 1/2 Inch Long Shackle Bolts with the Lock Nuts.

by:

Highly recommended for large inventory of great products that will be shipped promptly. Outstanding customer service that keeps you aware of the status of your order. It was such a pleasure doing business with etrailer. Thanks!



by:

The bolt diameter was too large for the slipper spring



by:

The customer service chat ensured I purchased the right trailer parts! Arrived right on time!



by:

The package with leaf springs and hardware arrived intact and well secured. Installation using 2 jack stands and a floor jack was not as difficult as I thought it would be. Time will tell how the leaf springs will hold up after repeated use in a saltwater environment.



by:

These bolts are really good bolts. The only thing about these is one lockout is a good quality nut and the other one is a cheap nut. One is a typical mashed nut and the other has 3 little punches on the last thread. Those do not hold very well at all. I have had a few in the past and they do not hold. So either get you a better lock nut or return these. Otherwise I would have these a 5 star rating

  • Should Bolt Hole On Leaf Spring Hanger Be Larger Than Shackle Bolt
    Hey Paul; it looks like the bolt hole has been elongated/enlarged from use over time. This is something that can happen from standard suspension wear. It should match the 9/16" bolt. With the hole being that large I would say it is time to replace the hangers before the hanger, or something else, fails from all the extra unwanted movement. You want to stick with the same height for hangers so you will need to measure to find a replacement. The height is the distance from the center of...
