AFAIK they should be the same. its easy to lift the rear. use blocks or get custom springs. the fronts the tricky part. everything is the same on the 150 as on the 250. just the brake discs are different to accommodate the extra studs.
Have you found a lift kit for your truck I'm in the process of trying to find a lift myself but not having any luck I already turned my t bars up and I want it higher please let me know if you have found one thanks
