Cancellation Policy

ALL cancelled orders are subject to a 5% fee. We are sometimes able to waive the fee if you would like to change your order to another product of the same or greater value. If you need to cancel or change an order, please contact sales@dieselpartdeals.com

Kryptonite, Flux, HSP, Synergy, EvilFab, Steed Speed and SDP Products - 20% cancellation fee if cancelled, due to extended lead times.

Lead Time Notice

Many products we sell carry a lead time, specifically powder coated products which are made to order. Once you have placed an order for a powder coated item, we are unable to cancel the order due to the custom nature of the product. If you need a product quickly, please contact sales@dieselpartdeals.com before ordering to check if we have the part in stock.
