Item Description

It may seem like an insignificant item, but the gooseneck ball is the FIRST and ONLY connection your hitch and trailer has to your truck, so it should stand out from all the rest as being reliable, innovative, and manufactured with the very best materials to keep you and your family safe, right?

Truck manufacturers introduced their Tow Prep Packages a few years back and their popularity spread like wildfire. These underbed mounting systems keep the bed clean when you’re not towing by utilizing four mounting points in the bed and a center mounting socket.

While we weren’t the first manufacturers to come out with a gooseneck that fit into a single point system, that did give us an opportunity to observe the market and see what RV’ers were saying and problems they were experiencing. And, sure enough, we did find some complaints out in the field. What we found was the opening in the top of the ball allowed debris to enter the locking system, and all too often, making it fail to operate. The other issue we ran across was the ball freezing into the OE socket in cold weather or from corrosion, without a way to remove it once it was frozen in place. The last issue was theft.

Another advantage of not having any openings or locks to engage in the ball itself, is we are able to provide you with a solid, zinc coated ball that is durable and corrosion resistant. Because other manufacturers have designed their locking mechanisms to be on the top of their ball and drilled down through the center (plunger type lock as seen in the cross section illustrations here), which means their ball is hollow compared to our solid ball. Which one would you rather tow with?

With a PullRite ball, you not only have a strong, solid piece of metal your rig can attach to, but you can rest assured that is the case because ours is thoroughly tested and exceeds SAE J2638 standards.


So we set out to improve on as many areas as possible. But first, watch this short video and then we'll go into more detail...

Though we’ve minimized access points for moisture to find its way into our ball’s working mechanism, we knew there must be a preventative measure added to resist binding of the moving parts and overall corrosion. Metal-to-metal contact is a real issue as it promotes corrosion.

So for the exterior, we chose a zinc plated, mild steel that would resist corrosion much longer than a chrome plated ball would. But a mild steel exterior touching internal stainless steel parts would still cause corrosion and binding.

To avoid all this, as you can see in the illustration here, we separated all metals that weren’t alike with nylon washers to prevent them from touching one another, and even designed the internal locking plates in such a way that they don’t even touch the sides of the Gooseneck Ball Post sides or the end cap.
