If I buy the shocks that would give the truck a 2in lift, would it affect the wheel alignment?

If no, would a 3in?

 

Shocks do not give a vehicle lift, only coils along with shocks will give you the lift you want.
Some may tell you that you can use spacers and shocks, but on a truck with 144,000 miles, your coils are junk.

 

I was going to change those also.

 

OK, so what is your question specifically?

 

In red.

 

from what I have read the 2" lift will not affect the toe alignment just make the steering wheel crooked, 3" you start to need different radius arms to correct the camber/caster

 

I just installed 2" springs and longer shocks on my Disco. It goes down the road just as well as it did with stock suspension, maybe even better. From a driver's feel stand point the alignment seems okay. I'm going to have it aligned anyway as I just put new tires on it and want them wear evenly.

 

That's what needed to know, thanks Yeti.

 

Lifts don't affect the toe-in, only the caster. Even a 2" lift will affect it but it should be minimal and you probably won't notice it. A suspension lift will also affect the front axle center line (because of the panhard rod) but, again, 2" shouldn't be noticed.

 

be prepared for a lot more than 2" of lift from a set of 2" lift coils. I used 2" TF MD coils and measured 5" of lift in the rear and 4.5" of lift in the front. putting a 1" spacer set in the front today to level it out. My d1 has comparable miles to yoiurs so I would expect your factory springs are as sagged as mine were.
