Lift Question concerning an m1008.....

[uao85]

I am looking to lift my m1008 pretty soon and had a few questions about pinion angle. I am looking to lift it about 6" and have a set of 36" humvee mtrs on the truck so nothing too radical. My first question, I have heard that when you install a shackle flip on a blazer its a perfect cure for the bad pinion angle caused by the lift, but on longer wheelbase vehicles like a lwb or a sub that it will point the pinion too far upward and cause a bad pinion angle. Is this true? If so what can I do to fix this? Also what will I need to do to the front pinion angle after its lifted, I know I will need a longer driveshaft, but am curious if this is all I will need. I am thinking 6" front spring, and a 4" shackle flip in the rear with a zero-rate as far as the lift goes, or if the pinion angle is too much in the rear, maybe a 2.5" shackle flip and a 4" spring lift??? What would you guys do if it was your truck and this was the lift combo you wanted on the truck. What rear suspension setup would I need to go with to take care of the pinion angle as effectively as possible?

Steel shims are great. Some dont like them, but they can really help change your pinion angle without changing alot of stuff.

The rear should have a factory shim in it, you may just need to remove it after the flip is installed.
