I have the high lifter 2.5" lift. Very similar in design. I had to run wheel spacers even with my aftermarket 5+2 wheels. I am not a picky person so the ride quality from factory to lifted height feels the same. I know most will claim it's stiffer. I like my lift and I accompanied it with the arched arms and that combo seems to work super well for clearance.
Some extra info:
I chose the high lifter for the fact my pioneer dealer is a high lifter dealer and told me they would warranty my machine thru their extended warranty program as long as I chose to stick with high lifter products. If I were braver and did not worry about warranty coverage I would have gone cfab without thinking twice. However, I financed my machine and therefore purchased the extended warranty with the sole mindframe that if I'm making monthly payments I don't want to pay more out of pocket for repairs.
