The extended kingpin RV5 adds 10 inches, and the RV55 adds 5 inches of new clearance between your truck and 5th wheel trailer for shorter turns in a strong easy to install accessory.  

They both have a 24,000 lbs. Gross Trailer Weight rating and have a long lasting black powder coated finish. An extra ten inches between the rear bumper and the bulkhead of the trailer makes things easier especially if you’re towing with a Short Bed Truck. In most cases the RV5 eliminates the need for a slider or other more expensive options. 

The RV5 adds 3-1/2” of height and the RV55 adds 3-3/4” height to your kingpin box setup. 

All but a few kingpin boxes allow for the 10 inch extension but a few are made  with the kingpin plate going so far back on a level plane that a 10 inch extension will not work and can hit the inside of your pickup bed sides and that is where the RV55 with a 5 inch extension may work. Below is a picture to help understand the few cases where the RV5 may not work.
