Are those for the front or rear ?..
I see they list both--but I'm not exactly keen on paying almost 200 bucks for a pair,when new 5 leaf front HD springs are almost the same price..
My brother used Timberns in his '79 E-350 box truck he converted to a beavertail car hauler and loved them--made it ride nice unloaded,and kept it from sagging with a heavy vehicle on the bed..
