MORryde Pin Box Compatibility Checklist
Fifth Wheel Hitch Compatibility Checklist for MORryde Pin Boxes
Use this comprehensive checklist to ensure you order the correct MORryde Rubber Pin Box for your fifth wheel trailer. Complete each section carefully to verify compatibility and gather all necessary information before placing your order.
📋 Step 1: Identify Your Current Pin Box
The label is typically found on the side or top of the pin box assembly. Common manufacturers include Lippert, Dexter, Fabex, Leland, and others.
Write down: Manufacturer Name: _________________
This is crucial for finding the correct MORryde replacement. Examples: 1621SHD, 1116, 1716, 221-0031, etc.
Write down: Model/Part Number: _________________
If the label is missing or unreadable, you'll need to take measurements (see Step 4 below) or contact our AI Live Chat for assistance with identification.
⚖️ Step 2: Determine Your Trailer's Weight Rating
This is found on the Federal Certification Label, typically located on the front left side of your trailer near the entry door.
Write down: GVWR: _________________ lbs
For best results, weigh your trailer fully loaded as you would travel. This helps ensure you select the correct rubber spring rating.
Write down: Loaded Weight: _________________ lbs
MORryde pin boxes are ordered according to the GVWR of the TRAILER, not the GVW rating of the pin box itself. Each weight range (under 11,500 lbs, 11,501-14,000 lbs, 14,001-18,000 lbs, over 18,000 lbs) uses a different rubber spring calibration.
🔧 Step 3: Verify Hitch Compatibility
MORryde pin boxes work with standard fifth wheel hitches. Not compatible with gooseneck-only setups (unless using a gooseneck adapter).
Ensure your fifth wheel hitch is rated for your trailer's pin weight and GVWR. Your hitch capacity should meet or exceed your trailer's requirements.
Hitch Capacity: _________________ lbs
Ensure there's sufficient clearance between your truck cab and trailer during tight turns. MORryde pin boxes maintain similar dimensions to factory units.
📏 Step 4: Take Measurements (If Label is Missing)
If you cannot find the manufacturer label, you'll need these three measurements:
Measure the distance between mounting bolt holes (side to side and front to back).
Bolt Pattern: ________ x ________ inches
Measure the overall width of the pin box from outside edge to outside edge.
Width: _________________ inches
Measure from the center of the king pin to the center of the first row of mounting bolts.
Distance: _________________ inches
With these measurements, visit MORryde.com and search for their "Rubber Pin Box Identification Guide" to convert your measurements into a MORryde part number, or use our AI Live Chat for assistance.
🛠️ Step 5: Installation Preparation
Basic installation requires: socket set, torque wrench, jack stands or blocks to support trailer, and penetrating oil for old bolts.
You'll need to safely support the front of your trailer while removing and replacing the pin box. Never work under an unsupported trailer.
MORryde provides detailed installation instructions with each pin box. Review them before starting to ensure you understand the process.
✅ Step 6: Final Verification Before Ordering
Use our MORryde Fit Chart to match your current pin box manufacturer/model with the correct MORryde replacement part number.
Based on your trailer's GVWR, choose the appropriate MORryde model (-03 for under 11,500 lbs, -04 for 11,501-14,000 lbs, -05 for 14,001-18,000 lbs, -06 for over 18,000 lbs).
Double-check that the MORryde part number you've identified matches both your current pin box AND your trailer's weight rating.
