Frequently Asked Questions

Q: Is this king pin kit compatible with all kart chassis?

A: This kit is specifically designed for 2008+ PRC, Charger Prodigy, and similar chassis. Please verify your current king pin length (3.75") before installation to ensure proper fitment.

Q: Why is the 3.75" length important for my steering setup?

A: The 3.75" length is the standard for many modern PRC and Charger karts. Using the correct length ensures that your caster and camber adjustments remain within the manufacturer's recommended geometry for optimal tire contact.

Q: How do the included washers help with my kart's handling?

A: The included 0.060" and 0.030" washers allow you to fine-tune your spindle height. Adjusting these spacers is a critical part of dialing in your front-end geometry to maximize grip and steering response.

Q: Should I replace both king pins at the same time?

A: Yes, it is highly recommended to replace both king pins simultaneously to ensure even wear and consistent steering performance on both sides of the kart.

Q: What is the benefit of the AN-grade 6 drilled bolt?

A: AN-grade hardware is aerospace-standard, offering superior tensile strength and fatigue resistance compared to standard hardware. The drilled bolt allows for the use of a safety pin, ensuring your king pin nut stays locked in place under the high-vibration environment of racing.
