Just to put it out there....New Owner of a 2004 Yukon XL 1500 2WD so I do apologize for starting at the basics when I'm sure it's been discussed before. To put it simply the thing sucks going over tiny bumps....my camaro feels way better going over the same area So my question is after searching the first 2 or 3 pages of the suspension section I can't really find anything in regards other than lowering....Where is the best place to obtain a complete suspension rebuild/change... I've seen a few posts about don't use Detroit Axle and going off the quick 5 second look on amazon looks like a cheap china made item. Where does everyone procure parts from? For example the camaro has phastekperformance.com and it houses EVERYTHING you need for the car. Looking to replace shocks, control arms, etc Thanks for the help!
