[crazy longhorn]

Lowering blocks work on a coil rear setup, as the axle is bolted to the top side of the trailing arms. I agree with Project 70, a 2 1/2 4 drop is about the right amount for a driver/hauler. If you go much more than 4" in back, you will need to notch the frame for axle clearance. Flipping the axle on a leaf truck should net you 5-6" of drop(depending on the thickness of the spring stack). I have done my longhorn this way,& figured a little over 6 " of drop after the flat helper & a couple short leafs were tossed. I then relocated the spring hangers down on the frame approx 1 1/4" to raise it back up a bit(5" drop, with 2 3/4" of clearance tween the frame & axle......no bumpstops). i dont have any problems with bottoming, but those old Longhorn springs were pretty stiff to start with. A spindle, or spindle /spring combo would probably be the best no hassel way to do the front. One thing to keep in mind on front spring drops is that the original springs can verywell be sagged 3/4 to 1" ........so a 2" spring may only drop you 1"from where the truck stands. Good luck.....crazy AL
