I chose a Hannigan for my conversion. The ride is super, handling is great, fit and finish are next to none. Check the number of moving parts. The fewer moving parts the less trouble down the road. Ask owners about suport from the maker. I don't think you will find any complaints about Hannigan's suport. Be sure to check with others that have had kits installed by the installer you are using. The installer makes a world of difference. A good installer can tweak a not so good kit and make it great, a bad installer can make a great kit junk.
