R&P Service Insight
This unit is the industry standard for professional-grade gooseneck trailers requiring a weld-on outer tube configuration.
- Adjustment: Offers 8" of total vertical travel for trailer leveling.
- Pin Integrity: Uses a 3/4" load-bearing pin for maximum shear strength.
- Anti-Rattle: Features a set screw to eliminate play between the inner and outer tubes.
R&P Knowledge Hub
Compatibility: Designed for trailers utilizing a 4-1/2" round outer tube receiver. Fits standard 2-5/16" gooseneck hitch balls.
Vehicle / System Fit: Professional-grade gooseneck trailers, livestock haulers, and heavy equipment trailers.
Installation Notes: Outer tube requires professional welding to the trailer frame. Ensure proper gusseting for full capacity rating.

R&P Repair Insight
Before ordering, verify your current tube diameter and shape. This unit replaces 4-1/2" round outer tube assemblies.
- Check Diameter: Verify 4-1/2" OD for the outer tube and 4" OD for the inner tube.
