These spacer rings are designed for use with Mazworx VQ adapter bell housings. The bell housings are machined to fit the input shaft bearing of the VQ35DE transmission. However, as newer transmission models were released, the size of the input shaft bearing was reduced. To ensure compatibility with these updated transmissions, we offer spacer rings that adapt the bell housing to fit the smaller bearings.

If you’re unsure which transmission you have, you can identify it by measuring the input shaft bearing diameter.
