3.88 Ring and Pinion Bolt Set (Swing Axle Diff)

This set of 8 high-strength bolts is designed to secure the 080 ring and pinion gear to the differential in swing axle gearboxes used on classic aircooled Volkswagen models. These bolts are a critical drivetrain component, holding the ring gear firmly in place on the differential carrier to ensure correct gear mesh, smooth power transmission, and long-term gearbox reliability.

Manufactured to the correct specification with an M9 x 1.0mm pitch thread, these bolts are suitable for use during gearbox rebuilds, differential servicing, or ring and pinion replacement. Due to the high loads experienced within the final drive, it is strongly recommended to replace these bolts rather than reusing old or stretched originals when carrying out transmission work.

Ideal for restorations, performance builds, and routine gearbox overhauls on all aircooled VW models fitted with swing axle rear suspension and gearboxes.
