I had EFS shocks and couldn't complain about em. When they crapped out recently I replaced them with Bilsteins and they are much better, not that I wasnt happy with the EFS, but they are in a class of their own imo
Just for interests sake I've been quoted 1550 for the full kit installed.
Dobinsons are local to me and thought they'd do an okay price, came back as 2000+ until I showed them an ebay link for 1350, they said they'd match but I'm looking at the EFS ones simply because I don't need to do any work.
Sorry for hijacking Luke, hopefully info helps you as well.
Don't get me wrong on this but your choice of shocks is your own.
From what I have seen, everyone has a choice, as it should be but, it doesn't mean they all work correctly.
So called big named brands totally fail.
Think before you buy.
