Gear 3rd 4-Spd (Fiat 124 Coupe Sedan 1967-69) - OE NOS

Factory OE 3rd Gear for all Fiat 124 Spider and Coupe with 4-Speed transmissions from 1967-69.
21 teeth.
Third gear is one of the hardest worked gears in the 124 transmission.
It is always a good idea to consider preventatively replacing 3rd gear when doing a 124 transmission rebuild.
Note: as used 124 series transmissions were swapped between model years in lieu of rebuilding, we recommend carefully checking the tooth pitch on all 124 4-Spd transmissions' 3rd gear.
(33' cut pitch on this 3rd gear P/N 4155237)
(Later 1969 4-Spd uses a 31' cut pitch 3rd gear P/N 4191076)
