Suspension confusion?

[RiggRMortis]

Can't seem to figure out what shocks/struts to get. Most sites don't have a Megacab / extended quad cab option in the search criteria. I know my 1500 Megacab is somewhere in between a 1500 and a 2500 and I'm not sure what suspension I'll need to buy. Current shocks have Chrysler logos on them but I can't see much else. (looks like the previous owner tried to remove the labels and failed) Pretty sure it's not lifted, might be leveled.

So do I need parts for a 1500 or a 2500?

Also, what shocks would give me the best ride without breaking the bank? Mostly road driven with the occasional mild off road trek to get to a camping/fishing spot. Gravel roads as well.

3rd gen MegaCab uses 2500 frame, suspension and running gear. A 1500 Mega is only called that due to it's towing & payload capacity with the gas engine. Same truck with a Cummins is a 2500.

Thanks, that's what I figured but didn't want to buy parts and end up with the wrong ones.
