Is it the best quality kit on the market? No, but for the price it really cant be beat. i had the 4" xflex short arm kit on mine for awhile and it was fine for awhile. then joints started to wear out. i replaced the trackbar with a jks immediately. i liked the coils and the shocks arent that bad either. I have since replaced everything except the rear coils after 2.5 years. Keep the joints greased and get a jks trackbar and you'll be ok.
