I had a 4" Tuff Country lift on my 2000 Ford F250 and hated the thing (I know, shame on me and yes I learned my lesson). To me it always sat *** end down. Had the blocks switched out for taller ones and it helped, but to my eye it never sat "level" I have a friend that has a 6" Tuff lift on his 72 Dodge and he seems happy, but his rear springs were custom made... FWIW.
Seems thats common place for Super Duty lifts; they always seem to sit with a reverse rake.
Truck now rides like a cattle wagon (due to the lift and Toyo M/Ts).
Got the 4. 5 inch tuff country lift on my 06 mega cab. Looks good, sits level. Pretty much this is purely a "looks good" kit. Truck now rides like a cattle wagon (due to the lift and Toyo M/Ts). If you plan on running your truck off road, buy the Kore. If you just want some inexpensive lift, then Tuff Country works. Because it uses block spacers above the stock coil Springs, I would imagine the front end will eventually start to sag. But overall it has worked fine for me, no complaints...
