Lifter Release Tool
Custom Lifter Release Tool Works on all V8 GM DOD/AFM engines 2005-2019 after 2019 may have DFM. This tool can't be used on DFM equipped engines. I highly recomend purching the kit with the VLOM plug especially on 2014-2019 direct injected engines. The VLOM plug will not work with 2019+ DFM equipped vehicles.
Disclaimer: The lifter release trick will not work if V4 mode is still active. In order to shut the system off it must be disabled in the tune. The VLOM mod is also highly recommended.
I recomend https://lt1swap.com/afm_delete.htm for shutting off AFM in the tune.
The tool is made of softer steel to protect the lifter and the block. If you hit it sidways, just like a nail it could bend. The end of the tool will need to be reshaped for stubborn lifters or use on multiple vehicles. It can be reshaped easily with grinder or file. Just try to avoid the spot that directly contures to the side of the lifter.
