Stay away from RRO,and stay away from OTT spacer lifts.
The Daystar spacer lift is 1000000000000000 times better then anything that RRO sells.
Though in 5000miles or so your going to wish you got a real lift because the ride from a spacer lift get's real harsh.
Oh and don't forget the "not included" stuff you need to do like extended brake lines,longer shocks(if not already included),and extended bumpstops to go with any lift.
