Special purchase. Weddle Industries has made a one time purchase of N.O.S. factory VW 4.57 ring & pinion sets for 091 and 094 transaxles. These are the real thing, made at the VW factory using the superior Klingelnberg Palloid system. Klingelnberg Palloid ring & pinions deliver superior strength, accuracy, durability and a significantly quieter operation than other gear systems. Available while supplies last.
