i just went to pepboys and picked up some end links for my car because the current ones broke. however they were 5 dollars a set and ive seen them as much as like 30 a set. are these very poor quality? i bieleve they are polyurathane bushings, but how can i tell for sure. why such a big price difference on such a simple part? also the shocks i got are Garbiel Pro Ryder Premium Gas Shocks, 20 bucks each. anyone ever use them before and are they decent? i dont need anything more the the stock suspension system on my car, just replacing worn out parts.

I have the same rear shocks on my car, and they work great. They were a big improvement over my old leaky oil shocks :P And the end links you bought are probably fine. Autozone sells endlinks for like $4.00 each which have poly bushings. They also sell energy suspension ones which look almost identical, yet they are like $20 per pair. I have the $4 ones on my front sway bar (don't have a rear one), and they work great. I think the only thing you pay for is the logo on the box...
