Customer Support
REAL HELP FOR YOUR SKYLINE. Order questions, fitment checks, or a part that needs attention—start here.
Contact support@zentuning.store. Include your order number if you have one. For fitment help, tell us your chassis code, model year, engine, transmission, and relevant modifications. Please do not email payment card details or passwords.
Order help & tracking
Need an update? Email us with your order number and the email used at checkout. If you created an account, you can also review your orders in My account.
For an address correction, order change, or cancellation request, contact us as soon as possible. Changes depend on whether processing or shipping has already begun.
Find the right fit
Tell us whether your Skyline is an R32, R33, or R34 and include the full chassis code—for example BNR32, BCNR33, BNR34, HCR32, ECR33, or ER34. GT-R and GT-T parts are not automatically interchangeable.
Send the product name or page link, engine and drivetrain details, and any modifications that could affect fitment. Clear photos can help. Ask before ordering or installing if you are unsure.
Shipping & delivery
In-stock parts normally ship from Boston, MA in 1–2 business days. Carrier transit time is additional. Special-order, backordered, and freight items may have different lead times.
Current shipping options include free US ground shipping on orders over $750, $24.99 ground shipping below that threshold, $59.99 express shipping, and $69.99 tracked shipping to Canada. Available options and the applicable charge are shown at checkout. See our Shipping & Returns policy for details.
If tracking stops moving, a delivery appears missing, or you need help understanding a delay, send your order number and tracking details so we can investigate.
Returns & fitment guarantee
Unused, uninstalled parts in their original packaging may be returned within 30 days. Electrical parts that have been plugged in, custom-tuned ECUs, and special-order parts are final sale, subject to applicable legal rights and remedies for defective or incorrectly supplied goods.
Email us before shipping anything back. Include the order number, product name, reason for return, and photos if relevant. We will provide the correct return instructions and address.
If a part listed for your chassis does not fit, contact us for an exchange or refund, including return shipping, under our fitment guarantee. Do not modify or force-install an incorrect part.
Damaged, incorrect, or defective items
Contact us promptly with your order number, a description of the issue, and photos of the item, shipping box, packaging, and shipping label. Keep the packaging while we review the issue.
Do not install or continue using a damaged or unsafe part. For a suspected warranty issue, include when and how the issue appeared and any installation details. We can help identify the appropriate next step.
Payments, account access & privacy
For payment questions, send your order number and a description of the problem—never your full card number, security code, or password. Use the account login screen’s password recovery option if you cannot sign in.
For requests concerning your personal information, email support@zentuning.store from the address associated with your order or account. See our Privacy Policy for details.
