Boat Trailer Leaf Spring Slider Single Axle PAIR For 20 inch Double Eye Springs

This is a single set, hot dipped galvanized axle leaf spring slider for 20 inch double eye leaf springs. This slider is made of heavy duty 2 inch x 2 inch steel angle. Depending on your frame, this spring slider is made to be bolted or u-bolted to your boat trailer frame. It is intended to mount your suspension system, including the leaf springs and spring shackles to your trailer axle. This listing is for both sides, so you will be receiving a pair of sliders and this leaf spring slider will ONLY use 20 inch double eye leaf springs.


This spring slider includes fender brackets to be able to mount your single axle fenders. The fender mounts are 29 inches apart, so you are able to mount 29 inch fenders at the very bottom, or 30 inch – 32 inch fenders slightly above the bottom of the fender (most commonly used fender) and would use 3/8 inch diameter trailer bolts.


This model of leaf spring slider uses 20 inch double eye leaf springs in any carrying capacity and number of leafs. So using this length of spring is a must!


Typically there are two reasons why you would be interested in this product. One, you currently have this part on your trailer and over time, they have either rusted or broke and are in need of a direct replacement. Or you are looking for another way to mount your suspension system to your trailer frame because your current leaf spring hangers have gone through the same rusted or broken state.


We want to note that if you are not replacing your trailer axle, swapping to leaf spring sliders may change the placement of your leaf springs in relation to your axle. Your current axle may have a pre-drilled hole in it or welded pads to accept the leaf spring tie bolt, the bolt that holds the leaf springs together. If this leaf spring slider is an exact replacement, then little will change about your suspension system. Sometimes the fender brackets appear slightly different on newer designs than how they were made years back, but the function remains the same.


The single axle hangers have a left and right, front and back and as a reference to how they are positioned, you can look at the photos with this listing to verify. Please note, that the narrower hanger goes towards the rear of the boat trailer, as you will mount your leaf spring shackles to the outside of this hanger in order to mount the back of the leaf spring. To complete your double eye leaf spring slider suspension setup, you must additionally use trailer leaf spring shackles to complete your system. As well as, use ½ inch diameter 3 ½ inch long leaf spring mounting bolts to finish the assembly.


Regarding how to mount this assembly, you can either mount it exactly the same way your current slider system was, or one of two ways that we can list below.


1. Trailer bolts – Most common on I-beam trailer frames, using a ½ inch diameter through bolts you will drill a hole through the slider and your aluminum frame and using (2) bolts per slider, mount it to your trailer frame (so 2 holes per side).


2. Boat trailer U-bolts and U-bolt mounting plates – For square tubed frames, C channel frames and even smaller I-beam frames, there is no drilling involved as you would use ½ inch diameter u-bolts. The prime aspect here is to use (2) U-bolts and (2) plates per side that have matching widths to work with each other. It is important to select the width of u-bolt, that will not only be wide enough to go around your frame but also accommodate the width of the spring slider.


For example: A 2 inch x 3 inch rectangular tubing frame could use a 3 inch wide u-bolt and matching shackle. As the u-bolt is wider, you would set the u-bolt and shackle at an angle. Securing each side against the frame and then tightening it down. In the above example, the length of the u-bolt could be 4 5/16 inches to accommodate the height of the frame, thickness of the spring slider and the thickness of the spring shackle.


Not all methods of mounting these sliders is identical, but common diameter trailer frames are not too difficult to identify. Sometimes, you can measure your current hardware, and purchase matching replacements.


Mounting Hardware for this assembly is available separately, as not all trailers will require the same hardware. Here is a link to our Mounting hardware category so you can take a look at all the available options.
