Products Description

The 4th & 5th Shift Arm (also known as ARM; SHIFT, 4TH & 5TH, transmission shift fork, or selector arm) is a critical internal transmission component that engages the 4th and 5th gear synchronizer sleeves on Isuzu M100, M600, NLR, NMR, NKR, and NPR trucks. This forged steel arm moves the synchronizer sleeve to lock the selected gear to the mainshaft, enabling power transfer through the transmission.This shift arm is specifically designed for ISUZU M100, M600, NLR, NMR, NKR, and NPR series trucks – widely used for cargo transport, delivery services, commercial fleets, and municipal applications. These vehicles are typically equipped with MYY5, MSB5, or related 5-speed manual transmissions.
