wat lift is better for my 4 door 96 blazer

 

2" shackles/ 1.5" tbar crank($20-$100) is the cheapest way to go but the cv joints wear faster than normal in the front(

Then there is always the body lift($140-$220) this just raises the body off the frame so you can fit bigger tires, it does nothing to the suspension

then if you wanna spend a bunch of money you can get a 6" superlift ($1000-$2000)
