I got to jump in on this,first heres their add...
Design Specs:
Adds 1/2-inch, 1-inch, or 1 1/2-inches of lift
Can't be spit out like a lift block
Wide design helps eliminate wheel hop
Can adjust wheelbase back 1-inch or 1 1/2-inches
Allows for pinion angle correction at install
Integrated Bump-stop pad
CAD Designed and CNC cut
Supplied with kit are shock relocation tabs
The welding part doesnt bother me at all,the rest does!
(1.) These things are still blocks and are not any longer than any quality block Ive ever seen(so you gonna see some axle wrap).
(2)Width means absolutely nothing.
(3)You cannot adjust the pinion after the install.
(4)While they may be longer than stock they are still shorter than a quality spring perch.
I'll keep my u-bolts and lift springs!
If you want to run flat springs,move your eye mounts!
