"Superlift 2.75'' lift system" any good?

[lsu_beaux]

i saw where superlift had a 3.5 inch lift for tahoes and 1500 trucks. But the picture of it is in the chevy 1500 catagory...im lost i dont know.. The front is a cross member lift and the rear is spacers. I couldnt find anything on any forum about it so i was wondering if any of yall have.
here is a pic and the lift on the website:

looks like it could work but cost out the ass for installation with all the cutting n welding. It would prob be cheaper to buy a 4" lift n cost less.
