This is a complete rebuild kit for Mazda’s “7 inch” differential, used in all NA2 and NB1/NB2 Miatas from 1994-2005 (excluding 04-05 Mazdaspeed cars). We have gathered the highest quality components, including Japanese SKF tapered roller bearings, and genuine Mazda seals. We even include a quart of tried-and-true Redline gear oil so you’re ready to roll once your diff is rebuilt (your Miata requires almost exactly one quart). This kit pairs great with our 5.38:1 gearset while during the swap, or if you just need to refresh your high mileage, leaky diff. Professional installation is highly recommended, as special tools AND techniques/skills/experience are required to do the job correctly.
Included in the kit:
- SKF Front and Rear Pinion Bearings
- SKF Carrier Bearings (2x)
- Genuine Mazda Crush Sleeve
- Genuine Mazda Pinion Seal
- Genuine Mazda Axle Seals (2x)
- REDLINE 75W90 Synthetic Gear Oil – One Quart
- Printed guide on setting up the differential (for reference – professional installation recommended)
