The EXECUTIVE Fifth Wheel-to-Gooseneck (Torsion-Flex) Pin Box

The EXECUTIVE Fifth Wheel-to-Gooseneck Pin Box is a Torsion-Flex pin box that replaces your fifth wheel king pin box with a SnapLatch gooseneck coupler, so you can tow a fifth wheel RV using a gooseneck ball instead of a bulky fifth wheel hitch. It frees up full use of your truck bed when you're not towing, and eliminates the cost of buying and installing a separate fifth wheel hitch if you already have a gooseneck ball. It's rated for up to 30,000 pounds of towing capacity.

The EXECUTIVE Fifth Wheel-to-Gooseneck Pin Box is rated for up to 30,000 pounds of towing capacity and up to 6,500 pounds of pin weight, depending on the GVWR tier and model you select. It's important to stay within the optimal tongue and pin weight range specified for your specific model number, and overall tow capacity is limited by the lowest-rated component in your full towing setup.

The EXECUTIVE Fifth Wheel-to-Gooseneck Pin Box fits the LCI Rhino Box and LCI Turning Point frames, as well as Lippert 1621 and 1621 HD frames without modification. It also fits Lippert 1116 and 1716 frames, but those two require add-on shim plates sold separately. The Rhino Box model specifically does not require shim plates. Confirm your trailer's frame model before ordering.

The EXECUTIVE Fifth Wheel-to-Gooseneck Pin Box is available across GVWR tiers starting at 7,275 pounds with a 4.5K tongue weight rating and 16,365 pounds with a 6.5K tongue weight rating, with additional higher-capacity models available for heavier trailers. Choose the model that matches your trailer's actual GVWR rather than assuming a higher tier is always better, since it's important to stay within the optimal tongue and pin weight range specified for each model.

Yes, but only if the top of the ball sits within 1 inch of the truck bed. If your gooseneck ball is recessed deeper than that, or if you're unsure how your specific truck bed measures up, GEN-Y recommends calling their team directly before ordering, since fitment depends on this measurement.

Customers report up to 90% smoother towing with the EXECUTIVE Fifth Wheel-to-Gooseneck Pin Box compared to a standard rigid pin box connection. Its Torsion-Flex rubber torsion arms absorb road shock before it transfers to the trailer, which reduces bounce and jolt. Reported secondary benefits include increased cargo protection, possible improved fuel economy, and reduced tire wear on both the truck and trailer, though results vary by trailer weight and road conditions.

This pin box replaces your fifth wheel king pin connection entirely with a SnapLatch gooseneck coupler, so you tow with a gooseneck ball instead of a king pin. GEN-Y's standard EXECUTIVE King Pin Box, by contrast, keeps the traditional king pin connection for trucks already set up with a fifth wheel hitch. Choose this Fifth Wheel-to-Gooseneck version specifically if you want to tow a fifth wheel trailer using your truck's existing gooseneck ball setup instead.

The average break-in period is 1,000 miles. During this period, the rubber torsion components settle into their normal operating tension, so ride quality typically continues to improve over the first several trips. GEN-Y recommends periodically re-checking bolt torque during this period, since factory bolts commonly need a second tightening after initial use.

The EXECUTIVE Fifth Wheel-to-Gooseneck Pin Box carries a 5 year warranty on rubber components and a limited lifetime warranty on all remaining components. An optional TORSION-FLEX Lifetime Warranty upgrade is also available at checkout, which extends coverage on the rubber components and connecting hardware for as long as you own the hitch.

The base EXECUTIVE Fifth Wheel-to-Gooseneck Pin Box (part number GH-8056AL) weighs 180 pounds. Weight can vary by GVWR tier and frame configuration, since higher-capacity models and added components like shim plates or a safety chain increase overall weight. The unit is fabricated from steel and finished with a durable silver vein powder coat for corrosion resistance.
