i am thinking of lfting my 2000 silverado ext. cab 2wd. I was looking at fabtech 7inch lift and 35 inch tires. Any tips??

don't lift a 2wd its point less, if you want to do anything just lower it

It's not useless to lift a 2wd. Lifting one and running bigger
tires makes the truck a little more capable, but still nothing close to
a 4wd with a lift and mudders. I say go for the fabtech, good quality
product. 35s should fit fine with a 7" lift. Might want to
chek into some new gears though.
