Strut bar comparison

Ive seen a complete set of no name strut bars for around $40. But then for the better brands are at least $150. Does anyone know what the differences are and if $40 for the cheap ones are worth it or not?

If you have to ask, you don’t need the expensive ones.

whats the difference?

please search. once again, if you have to ask what the difference is, you wont need the better more expensive ones.
