overlander is right you dont need spring compressors and you dont need to undo the trackbars. however undoing the trackbars will help. however the spring compressors are very dangerous so any time you dont need to use them DONT. i have see springs launch out of those things and destroy stuff in a bad way all because someone didnt put them on right and didnt use the provided safety straps. do what the others have said put it on high jack stands, take off the tires, use a floor jack to lower the axle after removing the shocks (or socks lol ) then lower the axle with the floor jack till the springs unseat and then go about an inch lower they should come out with ease then put the new ones in and jack it up SLOWLY until you can see that the springs have seated properly, then bolt on the new shocks. then pump it up off the stands and put your tires back on. take your time and be safe! :thumb:
