The ZTech King Pin Set (P6073300019KZ / P6073300119KZ) with brass bushings is a complete steering pivot replacement for Freightliner Cascadia trucks. King pins connect the steering knuckle to the front axle and are the critical pivot point for all steering movement. ZTech manufactures this kit to European quality standards with OEM-level precision fit. Worn king pins cause dangerous steering play, accelerated front tire wear, and chassis vibration that worsens under load.

A: Fits Freightliner Cascadia trucks. Replaces OEM part numbers P6073300019KZ and P6073300119KZ.

Q: What is included in this king pin set?
A: Complete kit includes king pins, brass bushings, and all hardware needed for a full axle replacement.

Q: How do I know when king pins need replacement?

Q: Is this OEM or aftermarket?

Q: How long do king pins typically last?
A: King pins typically last 500,000–750,000 miles depending on load, road conditions, and lubrication maintenance.
