Shipping — Continental U.S. Only
Your shipping rate is calculated once at signup based on your address and locked for the entire 7-month subscription. The same shipping amount is charged every month — your monthly total never changes. We ship to the continental United States (lower 48 states) only.
Address changes: Your subscription ships to the address you provide at signup. If you need to change your address during the subscription, contact JT's Shock Oil before your next billing date so the change can be handled manually before your next shipment goes out.
Safety & Use
For RC shock/damper tuning and maintenance use only. Not for human consumption. Keep out of reach of children and pets. Avoid eye contact and prolonged skin contact. Clean spills promptly — silicone oil can create a very slippery surface. Avoid release to the environment.
