Return Policy

All sales are final

Because most products SDPI sells are specialty, performance, vehicle-specific, custom, or special-order products, all sales are final and non-refundable. SDPI does not accept returns or issue refunds because a customer changed their mind, ordered the wrong product, or no longer wants the product.

Review product descriptions, fitment information, quantities and options carefully before completing a purchase — see our full Terms & Conditions for the complete policy.

Damaged, defective, incorrect, or unsatisfactory products

If a product arrives defective, damaged in shipping, materially different from what was ordered, or missing components, contact SDPI within thirty (30) calendar days of delivery.

SDPI will review each situation individually and, where appropriate, may replace or repair the product, coordinate a manufacturer warranty claim, provide a partial or full refund, or provide another reasonable resolution. This 30-day resolution period does not create a general right to return merchandise.

If a package arrives visibly damaged, photograph the package and contents before discarding packaging, and notify us as soon as possible.

Custom tune files

Tune files are custom digital work built for your specific vehicle and are final sale.

Instead of returns, tune orders include revisions — see the Tune Revision Policy. Nothing in this policy limits SDPI's obligation to address a legitimate failure to deliver the product purchased.
