    Does my credit card get charged when I place the order or when it ships out?

    We use a pre-authorization payment process for all orders:

    Friction drives & conversion kits:

    • Your card is pre-authorized at checkout
    • We verify compatibility within 24 hours
    • Payment is captured after compatibility confirmation
    • If incompatible, the pre-authorization is released (no charge)

    All other products:

    • Your card is pre-authorized at checkout

    • No compatibility verification needed

    You'll receive email confirmation once payment is processed.
    What is pre-authorization and why do you use it?

    Pre-authorization temporarily reserves funds on your card without charging you immediately. This allows us to verify compatibility for technical products and ensure order accuracy before final payment. The charge is completed within 24 hours for standard items, or after compatibility confirmation for friction drives and conversion kits.
    How fast do you ship out?

    We process and ship most orders within 1-3 business days. Special products may require 7-14 days processing time.

    You'll receive tracking information via email as soon as your order ships, typically within 1-3 business days after placing your order.

    Please note: Your tracking may initially show "Awaiting Pickup" or similar status until the package clears customs and enters the local delivery network. This is normal and doesn't indicate a delay.
