Lunati Hydraulic FT Cam users..........

How are the summit brand lifters
Same pn as sealed power, HT 2011.
Box says made in Mexico any issues with them?
I have summit cam kit in my 318 Duster. Been in there now for 5 or 6 years, no issues. But I make sure they stayed pumped up as I can't seem to keep my foot out of it :)
