This JAS replacement pulley is engineered for use with Bosch alternators that use an 8 rib serpentine belt. The 8PV profile ensures correct belt alignment and consistent power transfer to the alternator for reliable charging system performance. Precision machined from high grade steel with a corrosion resistant finish, this pulley is dynamically balanced to reduce vibration and extend bearing and belt life.

Installation is straightforward and uses existing alternator mounting hardware and standard hand tools. Intended as a direct replacement for worn or damaged alternator pulleys, it restores smooth belt tracking and helps prevent premature belt wear. Confirm vehicle compatibility by using the Parts Checker before purchase and follow manufacturer torque and belt tension recommendations during installation.

Suitable for professional fitment and DIY repairs, this pulley is quality inspected to meet performance expectations and is ideal for restoring charging system reliability.
