Jetuplusllc Kingpin Coupler Block 3244 — Powder-Coated Bolt-On Rear Mount with Included Hardware

The Jetuplusllc Ball Funnel Kingpin Coupler Block 3244 is a bolt-on rear mounting block designed to attach to your fifth wheel kingpin coupler assembly, supplied with bolts, nuts and washers for straightforward installation.

If you tow with a truck and fifth-wheel trailer, the right mounting hardware can simplify alignment and improve the durability of the coupling area. This Powder Coated metal and plastic coupler block (OEM part number 3244) is built for attachment to the kingpin coupler assembly on the rear of your vehicle. It comes as a new, bolt-on component and includes the fasteners you need to secure it to compatible assemblies — note that the Ultimate Connection Hardball and the Kingpin Coupler Assembly themselves are not included.

How does this coupler block attach to my fifth-wheel kingpin assembly?

Installation is bolt-on and intended for direct mounting to the kingpin coupler assembly on the rear of the vehicle. The product ships with matching hardware to simplify fitting and reduce the need for separate fasteners.

• Mounting style: bolt-on for a solid mechanical connection.
• Included hardware: bolts, nuts, and washers provided with part 3244.
• Placement: designed for rear placement on truck kingpin coupler assemblies.
• Compatibility: intended to mount to existing kingpin coupler assemblies; verify fit with your system before purchase.

What materials and finish are used, and why do they matter?

This coupler block uses metal and durable plastic components with a powder-coated finish to resist corrosion and everyday wear. The combination gives structural strength while managing weight and impact points.

• Primary materials: metal for structural components and plastic where impact or weight savings are needed.
• Finish: powder coating for enhanced resistance to rust and environmental exposure.
• Durability: designed to withstand standard towing stresses when properly installed.
• Maintenance: powder coat reduces the need for frequent touch-ups compared with bare metal.

Will this block work with my truck and towing setup?

This part is designed for truck service applications that use a fifth-wheel kingpin coupler assembly and will suit users looking for a bolt-on mounting solution. Compatibility depends on the make and model of your kingpin assembly and any aftermarket components in use.

• Vehicle type: intended for trucks equipped for fifth-wheel towing.
