I actually like the ride better. Well the installation isn't to hard youll need to grind the area away for the ball joint spacer and get the old studs out of the ball joint i think thats the hardest part.
I recommend new ball joints on top makes it a lot easier. I didnt like the bolts for the spacer i went to tractor supply and got me grade 8 bolts, because the nut threaded out at the specified torque spec. The grade 8 stuff works great make sure to get the grade 8 washers also. In the rear the add a leaf wasn't bad at all i do recommend having new u-bolts even if yours dont look rusted or so they will be terrible to get out unless you have and impact and the chance of twisting the u-bolt it great.
The ride quality in the front stayed the same because i only put the spacer in and didnt mess with the torsion bars. The rear is a little stiffer but it feel smoother on the road its like the truck is not wabbly across the road. It will feel weird to drive when you put the lift on because your caster camber and toe will be way out. I recommend getting new inner and outer tie rod ends and the adjusting sleeves and intstalling them to in the mean while. It will save you money on the end because you won't have to get it aligned twice and the front end will be tighter and more accurate to adjust which makes your tires wear better and the ride be alot smoother. They recommend new shocks all the way around but I am running on all stock shocks at the moment i didnt off road it yet except for one driving up a hill but you will need new shocks for that. On the road I havent noticed major extending of the shock yet.
