Shipping/Returns
SHIPPING, RETURNS & REFUND POLICY
At CPP Diesel, we work hard to ensure every customer receives the correct parts and the best possible service. Because many diesel performance and replacement parts are vehicle-specific, we encourage customers to verify fitment before ordering. If you have any questions, our team is happy to help before your purchase. Contact us at sales@cppdiesel.com.
Shipping Information
Most orders ship as quickly as possible once payment has been processed. Shipping times may vary depending on product availability, manufacturer lead times, carrier performance, and seasonal demand.
While we strive to provide accurate delivery estimates, some products may require additional processing time due to supplier inventory, manufacturer production schedules, or freight carrier delays.
If there is a significant delay affecting your order, our team will work to keep you informed and provide available options whenever possible.
Free shipping promotions apply only to qualifying orders within the contiguous United States. Alaska, Hawaii, and international orders are excluded unless otherwise stated.

We want you to be satisfied with your purchase. Eligible products may be returned within 30 days of delivery, subject to the conditions below.
If you have questions about shipping, returns, refunds, warranty claims, or order status, please contact us first at sales@cppdiesel.com. Most issues can be resolved quickly without the need for a payment dispute.
