This flexplate is twice as thick as stock and has passed the stringent 29.3 SFI testing, making it legal for use in race sanctioning bodies specific to High Horsepower diesels. These units are a direct bolt-in and fit any OEM or aftermarket torque converter. Fits Allison 1000 2001-2018. No Discounts.
