USA Standard Gear Manual Transmission Input Shaft ZF

The USA Standard Gear ZF manual transmission input shaft (also called a transmission main drive gear or input gear shaft) is a replacement part for ZF manual gearboxes. The input shaft carries engine torque from the clutch into the transmission. It is a key part of the gearbox's power path, so a worn or damaged shaft can cause noise, poor shifting or lost drive.

Product Line Highlights:

• Replacement input shafts for ZF manual transmissions, including six-speed and five-speed designs
• Machined construction made to restore proper gear mesh and bearing fit
• Made by USA Standard Gear, which produces a full line of transmission, differential and general replacement parts
• Suited to transmission rebuilds and repairs when the original shaft is worn, chipped or damaged

Replacing a worn input shaft during a rebuild helps restore smooth, reliable operation. Pairing it with fresh bearings, seals and a new clutch is good practice. Choose the variant that matches your ZF transmission model and application.
