Pullrite Superglide Hitch Plate Tilts

Does your auto-sliding fifth wheel hitch plate assembly tilt to one side? Below are steps for two simple repairs to prevent possible damage from hitching up with the top plate at such an angle.

How to Repair SuperGlide Fifth Wheel Hitch Spring

The purpose of the Rocker Arm Spring on the Pullrite SuperGlide fifth wheel hitch is to maintain a level position for the rocker arm and attached top plate assembly. Over time this simple leaf spring can become bent or flattened. Our hitch is now almost ten years old, and one side of the spring had finally snapped off.

When I noticed the top plate on our hitch tilting to one side, I discovered that the spring under the rocker arm was broken. After replacing the spring, the top plate is once again always level and bounces back whenever tilted to one side or the other.

NOTE: Align Pivot Bolt to Tighten

The head of the Rocker Arm Pivot Bolt must align with its stop for the bolt to be fully inserted. The stop will prevent the bolt from turning so you can tighten it with just one wrench. Align the bolt properly and insert it completelt before attempting to tighten the nut. 

How to Replace SuperGlide Fifth Wheel Hitch Shims

If you have an older SuperGlide hitch like we do, you may have shims installed between the Rocker Arm and Turntable Cam Arm braces.

If not, and/or if your Rocker Arm is loose, get some shims from Pullrite. These shims will help keep the Rocker Arm tight, but over time they too can become rusted and flattened or bent.

Don’t have an auto-sliding hitch? You’re missing out!

I love my Superglide. With regular maintenance and frequent inspection, I hope to plan it performing well for at least another ten years. Keep those rails lubed!

  1. How do you stop the hitch from sliding for and aft? It is an older hitch and needs grease on the rails, not WD40

    • The Pullrite auto-sliding hitch cannot “slide for and aft” as the head must turn for it to move along the rails. If it is turning and sliding when unhitched, the stopper at top/center needs tightening. We only ever use white lithium grease on the rails. Check out our hitch overview video for more information.
