To complete your transmission upgrade from stock to a Tremec 3550, you'll need a new bellhousing as a result of an alternate bolt-pattern. This Ford Racing Modular Tremec Bellhousing is your solution! It links the Tremec 3550 with the 4.6L, 5.0L, or 5.4L modular engines. Minor modification is required for transmission clearance and mounting in some applications.
Note: Does NOT fit 13-14 GT500
