GMR Stage 4 Pkg - 1025 HP E85/Pump Gas - 2015-up Dodge Hellcat Challenger/Charger

This package was developed and tested in a partnership between Grudge Motorsports Racing and Demon Performance. Designed for those looking to gain more power from their 2015+ Dodge Hellcat Challenger/Charger while maintaining drivability and retaining the stock engine bottom end and transmission.

Our Stage 4 package includes all the initial upgrades of our stage 3 package but now with much more fuel available from the returnless dual pump system which now allows for E85, more boost, and more timing! With the provided pulley options you can run 93 octane pump gas safely for daily driving and with a simple pulley swap and a quick tune upload, you can enjoy the power of E85. This package will get you 925 HP on 93 octane and put your Hellcat in the 1025 HP range with E85!

Special Order Policy & Cancellations

Special order parts are defined by Grudge Motorsports, LLC as any product, auto part, performance part, tool, accessory, etc., that we do not currently have in stock, that are on backorder, or that we do not stock as a shelf item which may be due to lack of popularity or the part has various options that make each order unique. This does not mean the part is not currently available. Many manufactures keep less popular parts they produce in stock and can process orders we submit quickly. If the manufacturer has the item in stock it will normally drop ship directly to you within 5-7 business days depending on your location and the type of shipping required. Otherwise the factory may have to produce or final finish a part which typically ships in 3-6 weeks but can take up to 12 weeks or more for certain parts.

There is NO guaranteed delivery date for any special order and manufacturers often change the expected ship date several times. Contact us before making a purchase if you want to get more info on an estimated ship date which will help avoid cancellation issues.

ALL SALES ON SPECIAL ORDERS ARE FINAL. NO CANCELLATIONS, REFUNDS, OR RETURNS WITH EXCEPTION TO DAMAGED UPON RECEIPT OR RECEIVED A PRODUCT DIFFERENT THAN PRODUCT ORDERED. THE ORIGINAL MERCHANT TRANSACTION FEE (3-7% depending on your payment method) IS NON-REFUNDABLE AND WILL BE DEDUCTED FROM ALL RETURNED ORDERS.

Special orders are sent directly to the manufacturer and usually drop ships directly from them in many cases but occasionally ships to one of our distribution centers and then shipped to the shipping address provided at purchase. In these cases we work extra hard to expedite getting the order shipped quickly.

Updates on special orders are available upon request only and we do not provide phone support for special order status updates. If you need help with an order start by selecting the Orders link on our site or the Order Support button in the email received a time of purchase and submit the appropriate form. We will NOT respond to random emails or phone calls requesting status, returns, or cancellation.
