Has anyone lowered the rear of their f100 by flipping the front spring mount and redrilling the bolt holes? and what were the results/problems?

 

well, i didnt lower it, but i did replace the ones on my truck from a different model year, if ur looking for how they hold up, its been great, no frame problems, handles fine, everything is straight, and most importantly, it looks good, as for lowering, i have no advice there, srry

 

Yes, have done this on several f-100's. only critical thing to watch for is pinion angle.Depending on how much you lower it you may have to buy axel weges to realign the pinion. NAPA sell's these in different angles.good luck!
