King pin assembly is the core load-bearing component of heavy-duty truck steering systems. Worn or damaged king pins will lead to steering shake, tire deflection, abnormal tire wear, and even potential driving hazards during long-distance transport, mining and rural road operations.
As a professional factory of auto chassis spare parts, we supply fully matched complete king pin repair kits covering all heavy truck models. Our products are widely exported to aftermarket wholesalers and repair garages across South America, Africa, the Middle East and Southeast Asia.
Full Accessory List of Our Standard King Pin Repair Kit
Many small suppliers only sell single king pins without matching auxiliary parts, forcing repair shops to purchase scattered accessories separately and increasing procurement costs. Our integrated repair kit contains every replacement part you need in one package:
- 1 Main king pin spindle: forged 40Cr alloy steel, quenched & tempered for high load resistance
- 2 Wear-resistant copper alloy bushing: anti-abrasion for bumpy mining roads
- 3 Dust-proof oil seal & protective dust cover: to block mud, sand and rainwater
- 4 Supporting thrust washers, adjusting shims, circlips and grease nipples
All accessories are manufactured with unified dimensional tolerance, no cutting or grinding modification required during replacement
Step-by-Step Installation Tutorial for Mechanics
- 1 Lift the truck front axle, disassemble front wheels and brake assemblies
- 2 Remove the aged damaged king pin and thoroughly clean the inner cavity of the axle housing
- 3 Press the new copper bushing into the axle hole with hydraulic installation tools
- 4 Install thrust washers and oil seals, then place the brand-new king pin into position
- 5 Fix circlips and inject lubricating grease through the grease nipple
- 6 Test steering flexibility, fine-tune clearance with adjusting shims
Core Advantages of Our King Pin Repair Kits for Global Distributors
Premium Raw Material
The main pin adopts 40Cr alloy steel with high hardness and bending resistance, perfectly adapting to heavy cargo transport and rough African road conditions. Black oxide anti-corrosion surface treatment effectively avoids rust in humid coastal Southeast Asian regions.
Wide Model Compatibility
Our repair kits cover almost all mainstream HINO and ISUZU heavy-duty truck generations, one single kit fits multiple vehicle models to reduce your inventory pressure.
Friendly MOQ Policy
Low minimum order quantity: only 50 sets for king pin kits and steering parts. We fully support small trial orders for new importers to test local market sales.
Factory Direct Supply
We are the original manufacturer without intermediate dealers. Extra bulk discounts are available for full-container orders and annual long-term cooperative clients.
Hidden Losses Caused by Inferior King Pin Kits
Choosing low-cost poor-quality king pin kits will bring continuous extra expenses to your business:
- ✕ Thin low-carbon steel king pins easily bend under heavy load, causing frequent return maintenance
- ✕ Cheap bushings wear out within 1–2 months, raising repeated replacement costs for garages
- ✕ Defective oil seals cannot block mud and water, accelerating internal axle corrosion
- ✕ Inconsistent accessory sizes force mechanics to modify parts during installation, wasting labor time
