Matt at Indy4x is a great guy, works hard, has done a lot for the Isuzu community, has excellent customer service, and has great products. I have dealt with him some and have been very happy with the outcome.

Calmini has great quality products, has been in the business for many years, but tends to be lacking with their customer service some. I have delt with them on a few ocassions and am always happy with their products, but their customer service is weak.

Both companies detail what is included in their lifts, and are very different, so it kind of just depends on what route you want to go. Both kits will work. Since you are in CA, Calmini is a lot closer, so shipping would probably be less.
