    Question 1990 Suburban 2500 4x4 - A few q's...

    First off I'm the new guy here, looking to see if I can find help here.

    I am the engineer for my fire station and one of our squads is a 1990 Suburban 2500 4x4.

    I do have a few questions and I hope this is the right place,

    First off we have a rear heater its all beat up, was wondering is its easy to replace / find a new one?

    Tires are going to be on the list to get, is there a bigger size that would work?

    Was thinking of a little lift, what would be decent without having to change awhole hell of a lot.

    In advanced thanks for the help!

    I wouldn't worry about a lift, those ssuburban came stock with pretty small tires and very big wheel wells, you should be able to fit a full 33" tire with no problems, but if you do you want to lift it just get new leaf springs that provide more lift, then you don't have to worry about lift blocks. As for the heater I am not sure but I would just go to to start your search
