The Steering Knuckle Assembly is manufactured from high-strength forged steel, designed to withstand the extreme loads and impacts encountered during heavy-duty trucking. Its precision-machined surfaces ensure smooth pivot action, contributing to excellent steering feel and tire wear characteristics.
Whether you are performing a front axle overhaul or replacing a damaged knuckle, this Steering Knuckle Assembly delivers factory-quality components and straightforward installation. Each part is crafted to meet the highest standards of durability and reliability, ensuring your Sitrak C7H maintains precise steering control and safety.
The Upper Bushing is a precision-machined bronze component that provides a low-friction bearing surface for the kingpin in the Steering Knuckle Assembly. It is designed to withstand high radial loads and ensure smooth, wear-resistant pivot action. Made from high-strength copper alloy with self-lubricating properties, this bushing extends the service life of the kingpin and steering knuckle, reducing maintenance intervals and ensuring reliable steering performance.
The One-way Seal Ring is a critical sealing element that prevents lubricant leakage and contaminant ingress around the kingpin area. In the Steering Knuckle Assembly, it is made of high-temperature FPM rubber with a metal insert, providing a positive seal that withstands pressure fluctuations and extreme temperatures. Its directional design ensures that grease is retained while allowing excess pressure to escape, maintaining optimal lubrication and protecting the bearing surfaces from dirt and moisture.
The Steering Knuckle (Left) is a forged steel component that integrates the wheel spindle and steering arm. In the Steering Knuckle Assembly, it is precision-machined to provide accurate alignment of the wheel hub and kingpin, ensuring smooth steering and proper wheel geometry. Its robust design and high-strength material guarantee durability under severe load conditions, making it a vital part of the front axle system for the Sitrak C7H.
The Lower Bushing complements the upper bushing, providing additional support and a second bearing surface for the kingpin. Machined from the same high-grade bronze alloy, it ensures even load distribution and smooth rotation of the steering knuckle. Its installation is critical for maintaining correct kingpin alignment and minimizing wear, contributing to the overall longevity and reliability of the Steering Knuckle Assembly.
The Steering Knuckle Assembly is manufactured from high-strength forged steel, providing exceptional resistance to impact and fatigue. This ensures that the knuckle can withstand the extreme loads and harsh conditions of heavy-duty trucking, delivering reliable steering performance over the life of the vehicle.
This Steering Knuckle Assembly includes every component needed for a full knuckle service – the knuckle itself, upper and lower bushings, and a one-way seal ring. No additional parts are required, saving time and ensuring compatibility, while the precision-matched components guarantee optimal fit and function.
All bearing surfaces and sealing interfaces in the Steering Knuckle Assembly are precision-ground to exacting tolerances, ensuring minimal friction and wear. This results in smooth, responsive steering and extended component life, reducing maintenance costs and enhancing driver comfort.
The Steering Knuckle Assembly is manufactured to the exact OEM specifications, guaranteeing a perfect fit on the Sitrak C7H. The precision-formed geometry and correctly sized components ensure a hassle-free installation, reducing downtime and labor costs, while restoring the vehicle’s original steering performance and safety.
