2004-2005 MazdaSpeed Miata 4.10 Torsen LSD Differential Upgrade Kit. Includes the 4.10 Ratio Torsen Limited Slip Differential, MazdaSpeed Miata CV axles, and Mazdaspeed Miata Driveshaft. Removed from a 2004 Mazdaspeed Miata with only 77k miles. All components are in good working condition, fully tested prior to removal from a running and driving vehicle. Differential spun smoothly with no odd noises or grinding. Fluid has been drained with no excessive metal shavings or abnormalities. Will ship drained of all fluids. The housing is in good physical condition with no cracks or damage. Free of any major surface rusting or corrosion. The included driveshaft is in good usable condition with no excessive play or wear in the U-joints. Both axles are also in good usable condition and have the ABS tone rings as shown. Will work for either ABS and non-ABS equipped vehicles. The CV joints are not damaged in any way with no rips or tears in the boots. Includes the axles nuts as shown. This will ship in two separate packages.
This differential was only available in the 2004-2005 MazdaSpeed Miata models and features and reinforced differential casing with stronger axle units. However it will fit in any 1990-2005 Mazda Miata when using the included MazdaSpeed axles. This swap will not work with non MazdaSpeed axles, so if you need to replace the axles in the future you will need to find new MAZDASPEED axles
**If you are swapping this into a non-Mazdaspeed model, you will need to adjust your power plant frame alignment at the transmission in order to clear the larger Mazdaspeed driveshaft. This requires the 3 PPF bolts on the transmission to be loosened, and the PPF pushed away from the driveshaft for clearance. Please do your research regarding this swap prior to purchasing this to swap into a non-Mazdaspeed vehicle.**
