non gas charged hydraulic shocks in the front

[MancheKid86]

as the title says wondering about non gas charged hydraulic shocks in the front,
going away from stud top mount shocks because I can't find any with 15"-16" of travel.

found a set that are long enough without going to coil overs, but they are non gas charged hydraulic shocks.
 

anyone with with experience running non gas charged hydraulic shocks in the front?
unsure if stock shocks come with a charge in the front or not. I have had the current set for so long and they have a charge in them.

am I over thinking things, and they will be fine. Or should there be a gas charge. if so, how come?

Old GMs, and likely others, used an oil filled shock instead of a gas charged shock. I would think it’ll be fine.
