2011-2019 Powerstroke Full Lock Differential Kit (SPE-S200101)

Fits

Override the factory safety lockout on the electronic rear locker in your Ford Superduty. The SPE Full Lock Diff Kit is an add-on to the TCCM that allows the diff to stay locked in past 20mph. You can lock the rear end at 45, 50, and even 75mph. This kit takes about 10 minutes to install & maintains the factory switch! 

This kit causes no diagnostic codes or check engine lights. You will NOT have the light on the dash to tell you that it’s locked in. It also eliminates the lag time that the E locker has in factory form when engaging and disengaging.
