These TRD 4.0L superchargers are in high demand. Not necessarily easy to come by. Our Shop Foreman designed this kit to be the quickest way to put a supercharger you already own back into service, with much of the work performed by you or your mechanic, to help with cost and turnaround time savings. This kit is especially great for automotive repair shops where the mechanic can keep the cost and turnaround time down by completing the less difficult work in his repair facility.

This item is a do-it-yourself complete rebuild kit with a pre-built and timed rotor assembly. It is ready to install into your supercharger housing by you or your mechanic. It comes with a parts kit to rebuild the Eaton M90 Snout Nose Drive. Also included is a pair of rotor shaft needle bearings that are quality controlled checked and ready for installation by you or your mechanic into the supercharger housing.

Or...
To have a supercharger completely serviced by us, you send your core in for the rebuild. We have a Complete Rebuild Service which you can send your supercharger in to have performed. In this way you avoid a large core charge I would have to hold if I sent you a completely rebuilt and ready to install supercharger to you before a core supercharger is received by us.

Want to have it professionally rebuilt instead?
Our professional Complete Rebuild Service for the same Eaton M90 supercharger: Complete Rebuild Service Eaton M90 Gen5 TRD 4.0L. This includes new Thermal Barrier Rotor Coating. With this choice, the supercharger is completely remanufactured and returned ready to install, filled with oil. When comparing us to other "supercharger rebuilders" make sure they will be completely rebuilding the rotor assembly because almost all other advertised supercharger rebuilders are not able to perform the rotor assembly remanufacturing service nor rotor coating. The price may be similar, but the service isn't the same if they only intend to inspect and clean the rotor assembly. Our Complete Supercharger Rebuild Service price includes new ball bearings and Premium double-lip Viton rotor seals in the rotor assembly -- we will rebuild the whole supercharger when you send it to us for service.

Our do-it-yourself Complete Rebuild kit saves you an estimated $300-400 or gives a fantastic potential profit margin for an automotive repair shop.

This item is a rotor assembly that has been newly re-manufactured with the rotors newly re-coated and precision timed. It comes with a parts kit that includes all the parts needed for the complete service of the supercharger.

This eBay item is for an Eaton M90 Gen5 which shares the same bearing plate as some M112 superchargers but the M112 rotors are longer. The M112 kits are available, too. Contact us to ask about our other supercharger rebuild kits. The pictures show our timed rotor assembly with our Interference-fit Rotor Coating. Our Rotor Coating is very consistent because it is thickness checked during quality control inspection to ensure even application. Not all rotor coating available in the market is precision checked like ours. You can see that the bearing plate is precision CNC machined to set the ideal tolerances, giving you optimum performance. If you are not sure which you need, please email a photo of yours and we can help you identify it.

For the Shop Technician or DIY Do-It-Yourself person, this kit includes THE HIGH SPEED LAB™ re-manufactured Supercharger Rotor Assembly. Get the same Premium Quality bearings and seals used in our Complete Rebuild Service. This item has been designed by our Shop Foreman, based on years of successfully servicing Eaton superchargers to give you the Best Chance at Success™ when performing the supercharger rebuild service yourself.

Buy this item because the rotor assembly is already professionally re-manufactured for you. Our rotor assembly bearings are retained by an Aluminum plate designed and CNC manufactured specifically for this application. This is the only method of bearing retention we trust for our supercharger rebuilding services. Now, you can use this professional, reliable method to completely rebuild your Eaton supercharger yourself, saving you time and money. NO ALUMINUM WELDING REQUIRED. A U.S. Patent has been applied for by us to protect this, our bearing retention process from unauthorized use by anyone but the designer of the process or his legal beneficiaries, Patent Pending.

Our rotor assembly is built to the exact same specifications we use when we rebuild a supercharger at THE HIGH SPEED LAB SUPERCHARGER SHOP. To assist you in your assembly work, the tolerances are listed at the top of this section. All bearings and seals used are direct replacement or upgraded from the original part specifications and most importantly, the rotor seals are now a Double-lip Viton.

Here are a few details that may help you identify the supercharger you have.

The later Eaton M90 Gen5 TRD supercharger is usually painted Black instead of Alpine Grey. The upper and lower intake manifold is cast on to the supercharger housing. The nose drive has part of the intake runner cast onto it with a large TRD in raised letters.

The Eaton M90 Gen5 has 8 bolts in the Nosedrive bolt circle. With the Gen 1, 2 & 3 Eaton superchargers, this is a simple matter to determine because the Eaton M90 Gen3 has 9 bolts holding the Snout on. The M45 Gen3 and M62 Gen3 only have 8 bolts.

Providing a phone number, we can contact you at if there are any questions about your order is always helpful and leads to better service. We never have time to spam and never share information.

If your bearing plate looks way different, then just email us some phone pictures and ask our Shop Foreman to assist you in determining the supercharger type you have and what kit you need.

It is your responsibility to insure you request the correct rotor assembly. It is not always easy to be sure what supercharger you have because there are so many variations to the Eaton superchargers. With this in mind we want you to know that if the rotor assembly that arrives does not match the one you need to replace, contact us immediately. Do not panic and remember we have offered this because we want to help you get the right parts. We want you to have the right one and will work with you to exchange it when an honest mistake is made. Please help us by making your best effort to be sure which rotor assembly you need before you place your order. It is okay to tell us in your order email that you are not sure what you need. It can really help us to help you if you would email us a photo, and for this cell phone photos work great. We can prevent delays and frustration by looking at your snapshots for 5 minutes instead of all the extra work to exchange the part. Let us help you up front if you aren't 100% sure you know what you have and what you need.

What is done to the THE HIGH SPEED LAB's newly re-manufactured Eaton Supercharger Rotor Assembly?

We completely disassemble the rotor assembly plate including removing the old seals and bearings. The bearing plate is carefully measured and paired with a newly re-coated pair of rotors. The rotor coating is our special, exclusive interference-fit durable thermal barrier rotor coating, similar to Piston Skirt coating in durability and environment parameters. Our coating is durable in harsh environments found in configurations using nitrous injection systems, methanol or water injection. Then the rotor assembly plate is CNC machined to accomplish correct rotor timing and front rotor-to-bearing plate clearance, set at 0.006" to 0.009" and the mesh is split +/- 0.001" for optimum supercharger operation. Both rotor seals and rotor ball bearing have been replaced.

What does this item include?

This item includes the same high-quality parts we use in our professional supercharger rebuild services.

THE HIGH SPEED LAB™ re-manufactured Eaton supercharger rotor assembly with new rotor coating

Supercharger Oil suitable for the newly upgraded double-lip Viton rotor assembly seals, 8 oz. ounces
Permatex anaerobic red sealer for aluminum flanges, gasket maker

What will the supercharger rebuild process include when using this kit?

You, the buyer will have the parts that you need to replace the rear rotor needle bearings, rebuild the nose drive snout and install the rotor assembly yourself.

We recommend using Permatex Anaerobic Gasket Maker (PX#51817 NET .20 FL OZ or PX#51813 NET 1.69 FL OZ) which is designed for Aluminum flanges, available at some auto parts stores. Do not get any sealer or any debris in the rotors during installation. Do not use too much sealer or it will squeeze out into the rotors which will damage the supercharger. Completely clean any old sealer off the surfaces you are connecting the supercharger to because leaving the old sealer on the flanges will distort the supercharger housing when bolted together and cause failure. Follow the instructions on the package of the sealer for best results.

What is the tolerance goal for my assembly to work properly?

You will want a minimum gap of 0.006" to 0.010". The gap can be greater than 0.010" however this wide of a gap will allow for air charge leakage. The smaller the gap between the rear housing and the back rotor faces, the tighter the supercharger seal. The rotors should never touch each other or the housing internal bores, anywhere at all.

What Warranty Coverage is included with my purchase?

Our One-Year Warranty and our long-term eBay reputation will be your peace of mind. Warranty claim will require direct two-way contact before any financial action is taken in order for buyer to request a return authorization number. Warranty only in force if customer contacts us and receives the return number for processing first before cancelling, returning or charging back this item. Return of this item includes a mandatory 18% restocking fee. Please see our company policies for the complete details.

Are there pulleys available for my supercharger?

Yes! Contact us for more information about the custom pulleys we make. Check out the picture of our custom pulley in this item. Pulley shown is not included in this item purchase. The one pictured may not be the exact one available for this vehicle.
