Correct, but I blew the first set with stock coils. There shouldn't have been an issue. Same as the rears. I don't have more than 2" lift but if they are overextending that's an issue.
Bilsteins also don't dampen correctly offroad. They can't handle big bumps and whoops at all. They'll bottom out, bounce, and beat you to death. I've found 30mph is the sweet spot to soak everything up nice without issue, but if you hit a bigger hole or washouts at that speed you're going to know it! Also, I find that the rear shocks cannot keep that ass planted for nothing! It hops and bucks all over the place. Drives me crazy. I even get wheel chatter in sand which northern Michigan is full of.
So, if you drive mostly highway Bilsteins would be ok. Offroad though, find something better that is valved appropriately and can handle the abuse.
