Frequently Asked Questions

How do I know if my stability discs need replacement?
Common signs include excessive chucking or rattling between your truck and trailer, rough articulation when turning, increased noise during towing, or visible wear on the discs during inspection. If you notice any of these symptoms, it's time to replace your stability discs.

Is the RPB77-009 compatible with all MORryde pin boxes?
The RPB77-009 is designed for MORryde rubber pin box systems. Always verify compatibility with your specific pin box model number before ordering. Check your pin box documentation or contact us via AI Live Chat if you're unsure.

How difficult is it to install the stability disc kit?
Installation is straightforward for those with basic mechanical skills and tools. The discs are direct replacements that fit into your existing pin box assembly. Refer to your MORryde pin box manual for detailed installation instructions, or consult a qualified RV technician if you prefer professional installation.

Will replacing the stability discs eliminate all chucking?
In most cases, yes. Worn stability discs are the primary cause of chucking in MORryde rubber pin boxes. However, if chucking persists after replacement, you may also need to inspect and potentially replace the pin box springs based on your trailer's GVWR rating.

What's the difference between stability discs and replacement springs?
Stability discs control lateral movement and articulation, while replacement springs provide shock absorption and support the weight of the trailer. Both components work together for optimal pin box performance. If you're experiencing chucking, start with the stability disc kit. If you notice sagging or poor ride quality, you may need springs as well.

Does this kit come with a warranty?
Yes, genuine MORryde replacement parts are covered by MORryde's factory warranty. Keep your receipt and installation documentation for warranty claims.
