The RC4WD Lowboy Trailer Kingpin Upgrade: A Solution for Smooth Rides ------------------------------------------ The RC4WD lowboy trailer has one notable drawback - its tendency to sag excessively in the front, especially when carrying heavy loads. However, this issue can be easily addressed by replacing the standard aluminum fifth kingpin plate and front block with a specially designed upgrade. This new component raises the ride height of the trailer by an impressive 12mm without requiring any modifications to the towing rig. The best part? It installs seamlessly in all existing holes, eliminating the need for any complicated adjustments or reconfigurations. To complete the installation, you will need some additional hardware: longer M3 x 18mm screws and nylock nuts. Fortunately, there are recesses built into the upgrade that allow for a tidy and secure fastening process using these nylocks. After installing this upgrade, the ride height of the lowboy trailer's front end is significantly improved, boasting a new clearance of approximately 23mm at its lowest point.
