  1. no problems at all - Posted by: lou (6/1/15)

    didnt have any issues with alignment, drive line, or driveability after installing. My alignment guy didnt have a problem making my wheels run straight and i have no drive line vibration. I previously installed the 2.5 inch lift from rough country and already had all the holes drilled for 1/2 inch, i just reused my 1/2 inch hardware. everything lined up fine and i only had to touch up 2 holes on the radius arm bracket and add one extra hole for the pass side drop bracket and drill 2 smaller ones for the drivers side drop bracket brace. the ride is firm and very well within reason for a lifted truck...any softer and i think it would pitch and dive around way too much on bumps and feel out of control. VERY happy with this lift.
