It's normal for leaf sprung cars and trucks to droop until reaching the limits of the shock travel. The load on the shock rod when lifting a car like this is minimal and should not cause any damage, but if you are worried about it you can chain or strap the axle up to limit it's droop travel.Ramportin1 pic shows the rear mounted on the frame. I mount mine directly outboard of where his is on the leaf spring. I neglected to add to my earlier post that I have 4" shackle lift, which, combined with lifting on the frame would make the shocks bottom out and support the weight of the axle, resulting in premature failure. Main point is to figure out what is best for you. I put my fronts exactly where his are.
