    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.

We are proud to offer Red-Head replacement steering gear boxes for the third generation heavy duty Dodge Rams! No, this is not just another rebuilt box like what you'll get at your local auto parts store! These steering boxes are built in Washington state and offer unmatched steering control and longevity. We have personally ran several brands and have had the best results to date with the Red-Head.

This gearbox allows you to retain the factory steering shaft, as well as the stock pitman arm. This is a major advantage especially those with lifted trucks with dropped pitman arms, as you will not have to change your pitman arm.

HYDRAULIC STEERING ASSIST PORTS OPTION: Red-Head offers a porting option for those that are either already running a hydraulic assist steering, or plan to in the future. If you choose to make this upgrade to the box (from the drop down menu), your gear box will come with two pre-drilled and tapped ports with plugs. For clarification, hydraulic assist is NOT something your vehicle would have come from the factory with, rather it is an upgrade that adds a hydraulic ram to the steering linkage to aid in steering. Most vehicles do NOT have this option, thus if you are unsure if you have it, you probably do not.

IMPORTANT NOTE: To ensure proper fitment, check the steering box top cover of the box you are replacing. This product is designed to replace 4 bolt top cover boxes. Some vehicles can have an upgraded 6 bolt top cover steering box. If you are replacing a 6 bolt top cover steering box with a 4 bolt top cover box, you will need a factory pitman arm and tie rod end, or you can purchase the RH-2879U for a direct replacement.

You have the option for us to include a pre-paid return label. with the shipment for ease of returning your core. With this option, you will merely need to drop the re-packaged core with accompanying shipping label off at a UPS drop-off. Otherwise, it will be your responsibility to supply your own means of returning the core. Pre-paid return label option is only applicable to the lower 48 contiguous United States. Please contact us if you have any questions.

EVIDENCE: If you'd like additional third party evidence as to what goes into a Red-Head gear box and how much of an impact it will really make in your driving experience, check out a detailed review by acclaimed Turbo Diesel Register editor, Doug Leno.

Very disappointed in RED-HEAD Steering Gear Box
Very disappointed in this product purchased mine here at DPP on 2/14/2018 suppose to a heavy duty replacement for the Dodge factory equipment. I have to call B.S. on that here it is July 2020 and mine gear box is leaking like a sive and it's only got a 12 month warrenty. I'm not pushing some giant tires or anything I have NO LIFT and running slightly larger than stock tires LT285/70R17s I would not recommend this product my stock gear box lasted much longer than this one did!

Great gearbox for factory replacement!
Ordered this gearbox for my 06 from Tyler (Great Guy) while on a road trip to up to Washington from Texas right before Thanksgiving. Noticed I was getting a little more play in my steering wheel than I appreciated, he had it sent out and it was at my doorstep when I got home. Been running it for 7 months now and have had 0 issues. After whipping donuts and drifting through the desert in California I can assure you this gearbox will do everything you ask of it and more.

Very Satisfied
After research and replacing most steering components on my 2006 Dodge Ram 2500 Diesel truck which has a 4" lift that I still had a steering problem. I tried to adjust the set stud on top of the original steering gear, that did work, but I still had steering wander (Truck mileage 105,000). I vacillated between the Red-Head, Red-Head 6 bolt, and a 2008 beefer OEM gear. Once I read and watched their video on about how Red-Head remanufactures their steering boxes and the tight clearance on the bearings for the worm gear I was sold. After installing the new gear the truck has no wander (was at around 3"). I am extremely happy to have the truck back to normal steering. I also called Diesel Power customer service, and they were very helpful. Installation was easy (had a friend put the bolts in while I held it up). Removal & Install was about 2 hours. I'm mechanically inclined but never changed out a steering gear before. The Red-Head comes preset to install with no adjustments. OVERALL A+ for Red-Head and Diesel Power Products. I will use them again.

Redhead fixed my wander.
Before my steering wheel had to beld held at an angle to go straight. Didn't matter how many alignment shops I took it to. Ball joints and tie rods were tight. This steering gear stopped my wandering side to side.

Works great!! Customer service is really amazing!!
This gearbox works perfect for my son's 07 Dodge 3500 truck. No play now at all. Installation went surprisingly smooth for him and his dad, truck steers great for him now. The option to defer the core charge was awesome!! When calling with some questions, their customer service is the best around. Any additional items needed, this will be the first place I look. Great product, great service..can't ask for more.

Okay Gearbox. Not that impressed.
Gearbox was not much better than the one I replaced. I should have just bought one from NAPA. Still has play in the steering. All components on my steering system have been replaced. Also had miissing o-rings from my order that I had to track down.

Sorry to hear this box did not solve all your front end issues. I assure you, you'd be in much, MUCH worse shape if you had done a NAPA box. Most people go through 2-3 NAPA boxes, then end up getting a Red Head in the end. -Ben

Very happy with the purchase
All, had this installed today, after picking up, a 100% improvement, the 3-4inch play was gone! If you have over 100,000 miles this will be a noticable improvement. Thank you, Jake

I just bought a steering box for my 01 f-250 and my pitman arm is not matching up.. Any ideas what I can do??

There is a mid-model year split in 2000 / 2001, You must determine whether you have the early or later model steering box prior to ordering by counting the splines on the shaft. The early models have 32 splines, while the late have a 36 spline. Thus, the Red-Head #2764 will feature 32 splines, where the #2764NBS will have 36.


Does this include shipping of the core back to u???

Core return charges are up to the customer to send back to receive core credit.


Are the Redhead gears the same steering ratio as the OEM gears??

Yes, the Red Head Steering Gear box is the same ratio as factory. We recommend the factory ratio and not going to a tighter ratio due to the fact it puts a large amount of stress on the gears inside the box.


I have a 2005 Dodge 2500 Power Wagon with the 5.7 Hemi. I also have a drop Pitman on the original OEM gear box. Will the Red Head Gear Box be a complete interchange???

These should have the same gear box between gas and diesel applications. This will work with your aftermarket drop pitman arm yes.


Does this unit have the upgraded 1 1/4"" shaft like the upgraded oem ones vs the original 7/8"" shaft that keeps failing??

These have the factory sized shaft, however upgraded shaft material and bearings to make them hold up as a HD replacement.


It's a 2500 mega cab with a 6 inch lift it's hard to turn at low speed does this eliminate that problem??

These box's would aid in steering during low speed with their better design and gear ratio. Keep in mind a large oversized tire can make the steering much more difficult and steering assist may be necessary.


Would a borgerson steering shaft be compatable with the redhead for an 04 cummins 2500?

Yes it is compatible with the Redhead box.


I have a 05 dodge Cummins with a 13 inch lift my pitman arm caused my gear box to break I was gonna replace both is there a special kind of pitman arm I should put on it?

I would consider a drop pitman arm or perhaps a custom steering linkage set to accommodate the size if your lift.
