Frequently Asked Questions

Q: Why do I need the "long" version of these header bolts?

A: The long 8mm bolts are specifically designed for setups using thicker exhaust flanges or additional spacers between the engine block and the header pipe. They provide the extra reach necessary to ensure full thread engagement for a secure fit.

Q: What is the benefit of the drilled head on these bolts?

A: The drilled head serves two purposes: it helps maintain a balanced weight distribution on the bolt head and allows for safety wiring, which is a common practice in racing to prevent bolts from backing out due to high-frequency engine vibration.

Q: Are these bolts compatible with standard GX200 Clone engines?

A: Yes, these are designed specifically for Clone engine applications. They are ideal for custom builds where precision exhaust mounting is required to prevent leaks and maintain performance.

Q: Should I use a thread locker with these bolts?

A: While these high-tensile bolts are designed to resist loosening, using a high-temperature thread locker is a common best practice in karting to ensure your exhaust system remains tight throughout a full race weekend.
