Premium-quality Howo Kingpin engineered for extreme durability. Trusted by fleets worldwide — experience zero compromise with certified Sinotruk HOWO components. Your journey to unmatched performance starts here.
A worn Howo Kingpin compromises steering precision, tire life, and axle alignment. Our genuine Howo Kingpin kits are forged from 40Cr alloy steel, heat‑treated for maximum wear resistance, and precision ground to OEM tolerances. As part of our premium Howo truck parts lineup, each kingpin set restores original steering feel and eliminates dangerous play in the axle.
Whether you operate a Howo 6×4 dump truck, 8×4 tractor, or an older Steyr‑based chassis, the correct Howo Kingpin ensures safe lane holding, even tire wear, and longer knuckle life. Upgrade to OEM‑spec kingpins with hardened bushings and thrust bearings.
A new Howo Kingpin eliminates radial and axial play, ensuring straight‑line stability and responsive cornering.
Worn kingpins cause camber changes and tire scrubbing. Our kingpin holds correct alignment, extending tire life by up to 25%.
High tensile strength (≥980 MPa) and through‑hardened to HRC 28‑32 for superior wear resistance against impact loads.
Each Howo Kingpin kit includes pin, tapered roller bearings, thrust washers, lock pins, and grease fittings – ready to install.

“The Howo Kingpin kit fit perfectly on my 2017 HOWO 6×4. Steering wobble completely gone after installation. Very fast delivery to Nigeria.”
– Adekunle, Fleet Manager, Nigeria“We purchased 10 kingpin sets for our dump trucks. The alloy steel is much harder than local brands. Highly recommended.”
– Luis, Workshop Owner, Chile“Replaced old Steyr kingpins with AZ9719410001 – exact match. Now the truck tracks straight on highways.”
– Hasan, Transport Operator, Turkey“Great communication from the support team. The kingpin came with all bushings and thrust bearings. Saved my truck’s downtime.”
– Jiang, Owner‑Driver, ChinaWhy Professional Fleets Trust Our Howo Kingpin – The kingpin is the pivot between the axle beam and steering knuckle. A degraded Howo Kingpin not only compromises driver safety but also accelerates wear on tie rod ends, steering boxes, and tires. Our genuine kingpins are manufactured using advanced induction hardening and precision grinding to maintain a perfect cylindrical surface.
This ensures even load distribution and reduces friction. Every Howo Kingpin kit is packaged with high‑quality bronze bushings pre‑reamed to exact diameter (tolerance H7). We also offer oversized kingpins (0.25mm, 0.50mm) for axles that have been reamed previously. For severe off‑road applications, a nitrided version is available upon request. All products are backed by a 12‑month warranty against breakage or premature wear. Keep your Howo’s steering tight and reliable – choose only authentic Howo Kingpin components from authorized Sinotruk suppliers.
