Nissan GT-R R35 Version 1 Upgraded Bell Housing


This price includes a rebuilt ATR bell housing which comes with a 12-month warranty (if you’re under 800 horsepower).  We require your old bell housing as a core.  Any bell housing shipped without a core must include a $400 core charge (please add on the core charge before checkout).  Each upgraded housing will come with a used and thoroughly inspected damper disc, as Auto Technology Repair is currently unable to supply new discs. However, you have the company’s guarantee that each disc receives careful inspection before going out. Although they may have minor wear and tear, they will still work optimally.

What to expect with your ATR housing:

  1. Eliminated bellhousing rattle
  2. Hardened steel insert sleeves to eliminate bearing movement
  3. Upgraded Japanese made Nachi bearings
  4. A used aluminum bellhousing that may have minor scratches, corrosion, or debris
  5. A used damper disc that has been inspected for reliability
  7. Installation is available at our Gilbert, AZ facility.  Add on installation fee for full service repair
  8. Bellhousing will be shipped in a reusable box for you to return your core in

Product Description

This is our version 1 upgraded bellhousing that started it all.  With over 100 units sold in the past 3+ years, we’ve had a great track record for reliability.  While this housing is still available and still a viable option for your GTR, we recommend you check our our V2 housing for comparison before purchase.  The V2 offers all of the benefits of this V1, but with the addition of a modified output shaft and flange – To allow the rear driveshaft more room to float, and eliminate the cause of future failures.  We will eventually be moving our efforts towards producing only V2 housings, with the V1 being available on a “made to order” basis.

Please read on for more information on this V1 housing:

Benefits of Our Bell Housing

Purchasing an auto part online should never feel like an ordeal. ATR makes it easy for you to know precisely what you are getting. Once the bell housing is installed, you can expect the following benefits right away.

  • Hardened steel insert sleeves that eliminate any bearing movement
  • Reduced bell housing rattling and noises
  • Upgraded Japanese-made Nachi bearing
  • Shipped in a reusable box for you to return your core in

Damper Disc

Any damper disc you get from Auto Technology Repair will be used. Auto Technology Repair is unable to supply new damper discs at this time by themselves. However, you have the company’s guarantee that each disc receives careful inspection before going out. Although they may have minor wear and tear, they will still work optimally.

Greater Risk With GT-R R35

Due to its design, the R35 Nissan GT-R has a unique risk for bellhousing failure. From the first GT-Rs in 2008, the bellhousing has always been a weak point due to the separation of engine and transmission. The bell housing is mounted on the back of the engine where it has needed to adapt to a rearward-facing driveshaft going toward the transmission. Nissan was not able to come up with a better design where the transmission was more firmly in place. As a result, there is a chronic push and pull effect between the transmission and engine any time you accelerate or decelerate.

The bell housing is an unfortunate weak link in all of this. The aluminum housing that came with the car is typically incapable of withstanding such strong forces. GT-R drivers can tell when a problem arises because they can hear the bearings rattling around inside the car. Although the professionals at ATR are working to come up with a permanent fix, the upgraded replacement fixture is the best thing right now.

Auto Technology Repair works hard to ensure the new housing has a better chance of staying intact. Auto Technology Repair professionals create oversized bearing holes before pressing the hardened steel sleeve into position. After this is done, our workers replace the bearings with improved Nachi bearings. These components have been specially engineered to hold up to extreme abuse.

Signs of Damaged Bell Housing

A failed, or broken bellhousing will exhibit a rattling noise at idle, while stopped at a red light, and at low speeds.  The rattle is caused by the shaft moving around inside a damaged housing.


As with any component, it is important to remember that accidents can and will happen. Every bell housing that comes from Auto Technology Repair comes with a 12-month warranty. Only Nissan GT-Rs that go under 800 horsepower qualify for the warranty. In the event anything happens to your bell housing within the first year, we will replace the housing at no cost. We want every driver to have total peace of mind they will not have to spend a ton of money all over again if the bell housing breaks again.

  • We will cover ONE bellhousing failure (part and shipping).  If housing fails a second time, and vehicle has less than 1,000HP, we may issue a full refund upon return, inspection, and confirmation of failure at our discretion
  • In the event of a warrantied failure, we will replace the bearings on your housing.  We have never had a housing failure, aside from a defective or damaged bearing
  • Our warranty does not cover labor costs, unless you have the bellhousing installed at our Gilbert, AZ facility – Highline Car Care
  • Our liability is limited to the purchase price of ATR bellhousing plus shipping


Pre-Paid Core Charge

When purchasing your upgraded Auto Technology Repair Bell Housing, you must do one of two things:

Send Auto Technology Repair your core first so that we get the part before we ship out the bellhousing.
Pay a refundable $400 core charge up front and we’ll send you the bellhousing immediately.
Should you choose to ship your old core first, once Auto Technology receives your rebuildable core, you will receive a full refund of your core deposit. The cost of return shipping will be up to you.

Powdercoat Housing (Optional)

Not only will the part improve your car’s performance, but it can also enhance the aesthetic.

We will ship you the housing in any color you like. All you have to do is visit this link to see the selection of colors available. You have your choice of virtually any color you like, including:

  • red
  • yellow
  • orange
  • purple
  • blue
  • black
  • green
  • and many others.

Auto Technology Repair typically keeps the orange bell housing in stock because it is practically identical to the original equipment manufacturing brake caliper color. You should bear in mind the housing will not remain a show quality finish. For instance, you may notice some imperfections and casting marks within the housing. Fortunately, you can rest assured knowing the finish will still be exceptionally durable.

In the event you do want a show quality finish because you plan on showing your GT-R off in shows, then you need to contact us well in advance to discuss your options. However, you should remember that all powder coating is optional. It comes with an additional fee.
