Thread: which lifters for 5.3L LS4? Tuning out DOD while car is down for a collapsed Lifter

I think this part is true. You can keep the ENTIRE original setup and just turn off AFM/DOD and be fine.** No mechanical changes. Once you swap lifters, it's no longer the "original" setup. Does that make sense?


Edit.
**Assuming there are no mechanical issues. Seems to not be the case for OP.
