    Terms & Conditions

    We at Diesel Power Products offer a deferred core program in which we allow you to defer the typical upfront core charge when purchasing via credit card payment. All cores, whether the core charge was deferred or not, must be returned within 21 days from delivery date of product requiring core charge. Failure to do so can result in forfeiture of the entire core charge return. In the event you originally deferred the core charge, you authorize Diesel Power Products to charge you for the core charge.

    All cores must be returned to the original warehouse that original shipment was sent from. If a return label is provided in the original shipment, use this tag. If one is not included, contact us immediately, and we can provide you with the correct address of where the core(s) must be returned to, as well as an RMA (Return Merchandise Authorization) number. DO NOT rely on the return address on the original label as a source for where to ship to.

    If cores are shipped to the incorrect warehouse, your core money will be returned less the shipping cost for us to send the core(s) to the correct warehouse, or if you deferred the core you may be charged for the shipping amount.

    Cores that have been disassembled and/or have missing and/or damaged major components will not receive full core credit. Returned cores must be on a "like-for-like" basis, meaning that the returned core has the exact same fitment as the remanufactured component that was purchased. In the event that the core is not "like-for-like," your core may not be eligible for return / credit.

    Diesel Power Products has the right to alter this policy (i.e. extend the terms) for any reason. If you have an outstanding circumstance, contact us.

    What is a "Core Charge"?

    In order to understand what a core charge is, you must first understand what a core is. In the automotive industry, most products are manufactured from brand new materials. However, numerous products are also remanufactured, meaning that the manufacturer of the product takes a used product, typically removed from a vehicle, disassembles, and replaces all worn components of the master product. A great example of this is in regards to automatic transmissions in which the manufacturer takes an existing transmission, replaces all of the inner working components, such as the torque converter, valve body, etc. and merely reuses the case.

    Because aftermarket manufacturers require a steady stream of incoming cores to build, they charge a deposit on the core, known as a core charge, that is refunded upon receipt. In some cases, the core is not reusable, such as in the event of a cracked case, at which point the core deposit would not be credited as the core component is not reusable.

    If you plan on returning your core you have two options.

    OPTION 1:
    You can accept it, which means you will be charged for the part AND the core at time of purchase. You still have the option to send it back, and if you do, the core will be refunded back on the card used, presuming the core meets core criteria and the core is returned within 21 business days from originally receiving your order. If you have outstanding circumstances that would not allow the return to occur within 21 days, please contact us.

    OPTION 2 You can defer the core charge. If you defer it, you will not be charged a core at time of purchase. You will have 21 business days from the day you receive it to send it back. As long as the core is received within the 21 business days, you will not be charged. If 21 business days goes by and you do not send it back, the card on file will be charged the core amount. You still may send it back, and once received, we will issue the core amount as in store credit, pending any limitations as set forth by the manufacturer.Core deferral is limited to payment by credit card only.

Are you looking to increase the performance of your LB7 Duramax? Have you considered an injector upgrade? TDM injectors have revolutionized the injector industry by delivering a product most simply cannot, which is an injector that has been completely modified, not just a honed nozzle, to ensure you have a balanced set of injectors that will deliver the power you're after coupled with a smooth idle and a powerband that can't be rivaled.

Torque Diesel Motorsports' LB7 Duramax Stage 1 Injectors are capable of supporting +700hp with the proper power and tuning upgrades and at the same time they will support a simple 80 horsepower increase. TDM injectors are engineered to perform like a stock injector throughout the power band. This makes the injector very efficient which in turn minimizes smoke, minimizes exhaust gas temperatures, and makes for a very smooth running engine. While these have a top end limitation, its ultimately up to your choice of ECM tuning to determine how much power you want them to deliver. So whether you need some power to tow your camper or you are looking for weekend warrior fun, TDM injectors are your answer!

TDM injectors are hand built by OE trained technicians on OE Certified Equipment using only GENUINE OE PARTS! NO AFTERMARKET JUNK! TDM injectors are engineered to perform at the highest level. These are not simply a stock injector with extrude honed or EDM nozzles installed in them. TDM injectors are engineered to perform. Each injector's internal components have been re-engineered to allow more fuel flow while operating under the same rules as the stock injector. Each injector is matched with a specially designed OE nozzle that will accommodate the internal changes to allow the injector to function like is was originally designed to do. TDM injectors are precision matched and balance to 1.5% of each other. TDM injectors are built the same way every time. The flow rate from our first built injector is the same as our 500th built injector! No other company can do that and keep the balance rates that tight!

TDM injectors come with a 15 month unlimited mile warranty with a 90 day labor coverage. They have a "No Hassle Warranty" policy with these injectors. Each application has specific details so please ask about the warranty program for your vehicle.

  • It is critical that before installing new injectors that you ensure your fuel system is clean of any possible debris to avoid causing damage to the new injectors. Especially with 2001-2004 model year Duramax's, it is imperative to replace the injector lines at the same time as replacing the injectors.
