We Know Quality

The king pin is vital to a truck’s operation, so durability is essential. NAPA Truck King Pins are designed and tested to provide no less than the best performance to keep fleets moving.

We Know Our Products

The NAPA Truck King Pin range covers popular applications between 7.5 and 28-ton vehicles.

Quality Assured

All NAPA Truck King Pin components are designed and manufactured according to precise OE specifications. Every component has been rigorously tested against industry-leading quality standards to withstand extreme conditions.

Complete In Box

With NAPA Truck King Pin Kits, everything you need for installation is included in the box. All kits come complete with all necessary components including bushes, bearings, shims, seals, and lock nuts. This makes the NAPA Truck King Pin Kits perfect for both first time fits and the replacement of potentially worn or damaged components, ensuring each fitting feels brand new.

Built for Strength

In addition to extensive testing, all NAPA Truck King Pin Kits go through an induction hardening heat treatment process, giving each part an extremely tough outer layer capable of handling extremely high loads.

We Know How

At NAPA Truck, Know How is everything. While our king pins are built to handle extreme tolerances, we like to lessen the load where we can. All NAPA King Pins come equipped with a 1-year warranty, so any purchase you make is supported by our commitment to providing all our customers with industry-leading quality and service.

Our team of technical experts are on hand to provide support and guidance on our range of king pin products. This can cover anything from installation best practices to regular content releases addressing frequently asked questions regarding our other product ranges. Quality may begin with the product, but there is never an end to our Know How.
