ZL-1 # 1 Harrel Spring Modifiction

Yeah, that is a very effective method (and cheap!) of controlling "axle-tramp" on a leaf spring car. It can make for a slightly stiffer ride because you are effectively stiffening the front leaf spring segment but who cares.......get a Cadillac if you want comfort! Anyway, I've always fabricated my own though because I like the idea of directly tapping the upper strap with 3/8-16 threads so that once you get both bolts started a thread or two, you can then tighten them both up with a ratchet without having to fumble around with loose nuts and a wrench on top. Heck, on my last '55 Chevy C/Gasser, I think I had either 4 or 5 on each side. I've seen several 11-second cars get by with these clamps that don't even have traction bars.
