By purchasing any product or service from Weller Racing (online or otherwise), you agree that you bear the entire risk of using these parts/services.

Weller Racing is not responsible or liable for any damage to any vehicle, engine, drivetrain, or components related to the use, installation, tuning, or operation of any product or service—whether installed by Weller Racing, the customer, or any third party.

Product photos, videos, customer reviews, and promotional materials may reference discontinued products, previous pricing, legacy versions of components, or limited-time offers that are no longer available.

Only the items explicitly listed in the current product title and description are included with purchase.

Prior bundle offers, add-on pricing (including ECU flash discounts), third-party components, or past promotions are not included unless clearly stated on the product page at the time of purchase.

Weller Racing reserves the right to modify product specifications, included components, pricing, and promotions at any time without notice.

The current product page (title + description) controls what is included. Photos and videos may show optional items, previous versions, or example setups that are not included unless explicitly stated.

Some products may be updated over time due to availability, engineering improvements, manufacturing changes, or supplier changes. These updates may result in differences in appearance or design while maintaining intended function.

Unless explicitly stated on the product page, Weller Racing does not provide warranties—express or implied—on products or services.

Any warranty that is explicitly stated applies only to the original purchaser and does not cover damage caused by improper installation, misuse, racing conditions, lack of maintenance, alterations, or normal wear and tear.

Goodwill repairs, replacements, or assistance may be offered solely at Weller Racing’s discretion on a case-by-case basis and do not modify or waive these terms.
