What kind of Leveling kit? 1st Gen Tundra

Hello all! I am looking for help on finding the right leveling kit for my 2002 Tundra.
I have air bags in the back and a steel bumper on the front, so it always looks like my pickup is doing a nose dive.
I think I probably just need strut spacers, but I don't know what kind or what all I need with the spacers. With a couple inch lift will I need spacers for my front diff and bump stops?
Also, with this pickup at 420,000 km I don't really want to dump a lot of $$ into it...

 

Cheapest and best bet would be bilstein 5100's. Spacers will work but your ride will suffer.

 

ok, If I upgrade the shocks in the front, do I need to replace my springs as well?

 

Not necessarily.

You can get lift springs that will require less adjustment on the on the 5100’s if that makes sense. They will give the full lift without having to adjust the shock all the way out. I’d suggest checking out first gen Offroad as they are really helpful and know their stuff.
