0A5 311 277 A : Synchroniser ring for Volkswagen T4

The synchroniser ring is an essential component of the Volkswagen T4 manual gearbox, responsible for equalising the rotational speeds of the pinions during each gear change. Its progressive wear results in difficult gear changes, or even clunking noises, signs that replacement is necessary. As part of the restoration or careful maintenance of a classic Volkswagen T4, replacing this ring restores the original transmission behaviour. An intervention recommended for any enthusiast wishing to preserve the mechanical reliability of their vehicle in the long term.
