⚠️ Important Notes
Titanium + Nylon Care: The nylon insert is the weakest part of the assembly. Apply a small amount of Never‑Seize or similar to help the bolt pass through the nylon smoothly. Tighten slowly to avoid popping the insert.
Fitment Disclaimer: These measurements were taken from an OTK kart, but bolt lengths vary heavily between models and years.
