Most oem shocks have a 7" stroke and when used with the proper springs it is +- 3.5". Inexpensive Lowering springs being stiffer have less range [6"]so the springs may only move 2.5-3" in compression, obviously a stock shock cannot damp the same [actually 20% greater] force in less moving distance.
This 20% extra force in 27%-40% shorter distance overheat the shocks and causes wear and failure............always find an adjustable shock that is up to 60% stiffer, then dial in downwards to optimize.
Rebound [adjustability] is the parameter you are most concerned with, as compression is a function of unsprung weight [wheels, tires, brakes, suspension weight].
None of the non adjustable inexpensive aftermarkets are really suitable with lowering springs.
But a $70 shock is cheap and easy to change every 3- 4 years.
The adjustables are always more cost effective as they can be made to last twice as long with better control along the way.
If one races, slaloms, or uses shocks in severe duty [strokes per mile] bad roads......expect half the 3-4 year life.
