The Grannas Racing cast aluminum bellhousing for 2JZ/1JZ to T56 or T56 Magnum is designed with performance street cars in mind. Budget friendly, easy to install, high quality, heavy duty, precision machined, and better at noise cancelling than a steel bellhousing. These come with all hardware required for install.

These bell housings also come standard in all my GR700A kits (A for Aluminum bell). 

These cast aluminum bellhousings are precision machined to within .002 of center. While we are proud of our tight tolerances, we do recommend double checking your block for index to ensure you are within .005 runout for high performance applications. Sometimes manufacturers tolerances are not as tight or if your block was line bored this can cause more runout.

These bells USA made with heavy wall aluminum, which will dampen clutch and engine noise much better than the steel counterparts.

These bells feature a service window which is super beneficial if you need to adjust a hydraulic release bearing. Previously this would not be possible without removal of the transmission. 

Not only are these bells cast in the USA, but I have all the machine work done in the USA, for precision, accuracy and the ability to easily make changes if need be. I have checked these on eight different bone stock 2JZ engines and all of them land under .005 tolerance range. So most customers should fall within index but i highly recommend checking it just for peace of mind.

INDEXING / CHECKING RUNOUT
I do recommend checking runout with an index plate. I have been noticing more and more customer’s toyota blocks who are more out of spec than others. We are within .002 on the bells, and consistent, so the inconsistency comes from the blocks… A smaller percentage (about 15 in 400 bells sold) has shown an out of index condition, so I think it is better to play it safe and just check these to be sure. Out of index can cause premature failure of the input bearing as well as uneven wear and heat in the input gear. A tell-tale sign of an out of index bell can be a lot of rollover noise coming from the transmission. This is due to a side-loading condition on the input which over time can cause transmission issues. I do index plate rentals for any customer who purchased a bell or kit from me.

These will work with GM based TR6060 transmissions as well (if using a magnum front plate)
