Audi B5 A4 30v Quattro Rear Differential Service Kit

Don't let your differential come to a bad end; periodic fluid changes can keep it running smooth and silent for years to come.

Choose from premium Motul Gear 300 or Red Line 75W90 High Performance gear oil. Install the new axle shaft seals in the kit to keep your fresh oil inside the diff. Then add an extra measure of protection with ECS Tuning magnetic drain plugs, designed to attract and hold ferrous debris before it can abrade close-tolerance gears.
