Show original supplier description
The Mazda Motorsports MM03-27-200 is a remanufactured differential assembly for the 1994-2005 Mazda Miata MX5. It features a genuine NEW Mazda Torsen II Limited Slip Differential (LSD) unit paired with a known good 4.1 or 4.3 ratio gear set and differential carrier. The assembly is rebuilt using only TIMKEN bearings on the ring carrier and reassembled to factory specifications. This differential is available with either a 4.1 gear ratio or a 4.3 gear ratio, though the 4.3 ratio has limited availability. Please note that the aluminum differential housing is not included with this unit. As these differentials are built to order, please allow approximately 3 days for the rebuild process. Optional accessories such as fill and drain bolts, axle seals, and Red Line gear oil can be added. This differential is specifically designed for the 1994-2005 Miata MX5 models. It replaces previous part numbers MM0227200 and MM0227200a. Please be aware that this part does not fit the 2024 Mazda MX-5 Miata.
