Re: Tuff country 4" lift. Pinion angles?

Those are brand new springs unweighted. They will settle some and when you put the rest of the truck on it. How much is hard to say.

Re: Tuff country 4" lift. Pinion angles?

it will come down significantly under the weight of the truck body. it looks fine to me.

Pinion angles are irrelevant at this stage also

Correct me if I am wrong but I don't think the pinion angle will change when weight is added to the frame?

Re: Tuff country 4" lift. Pinion angles?

As the shackle rotates it changes the angle of the axle. Depending on the at-rest angle of the shackle the angular change of axle will be smaller or greater.

As was previously mentioned, I wouldn't mess with adjustments to pinion angle until you get the truck at final ride height.

They look short... Did you measure your stock springs? that era trucks had 52 and 56 inch springs. might have been 52 and 54inches
