Peterbilt Shift Lever Kits

Converting from an automated transmission to a Fuller manual in your Peterbilt requires a shift lever assembly that routes through the cab floor to the new gearbox. The factory automated setup does not include this mechanical linkage.

Kustom Truck Parts offers direct-fit Peterbilt shift lever kits for 389, 388, 386, and 367 models. Each kit provides everything needed for a clean, sealed installation from the floorboard to the shift knob. Kits are available in mid-block (10-13 liters, except Detroit 12.7L) and big-block (14+ liters) configurations to match your engine size and bell-housing geometry.

Pair with our transmission-specific Shift Lever Upfit Kit (available in 8LL, 10, 13, 15, and 18-speed variations) and Peterbilt clutch linkage kits for a complete conversion package. Contact our team to confirm the correct variation for your build.
