It was hard to see in the Pic, but if the 'mod' was leaf spring clamps. Yes. I used a combo of Home made copies of these offered by Mr. Gasket via the big box speed parts houses.

My 68 Would wheel hop the Bias-ply Firestones (Spring wined up) at the end of my dry burnout pior to stagging. I installed these and the hop is gone and they are hidden and an easy bolt on and off as required.

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.

They work pretty good (not quite as good as a good set of traction bars unless you run a bunch of the Harrell clamps) I run 2 pairs a side on my Nova and the axel/leafs will wind up a bit, but almost no axel hop. JS

[69z28302]

Thanks to the replys. Thats what I was looking for. Maybe something that works without adding traction bars.

You can also build your own "Super-Stock" style springs if you wanted to. The how to could be its own thread.

[JRSully]

make sure you put a piece of 1/4- 1/3" bar stock on top of the leaf springs (equal width to the leafs)and clamp it on top of the leaf springs with the Harrel clamps, Also keep an eye on them from time to time, if you hit hard (like I do) they will move around on you

[YENKO DEUCE REGISTRY]

Also, make sure they are not too wide, as they will rip right into the frame rail when you hit it hard.

What tires are you planning on running?

[69z28302]

Street Tires.


It looks like in the picture that he use's a piece of flat stock on the bottom and straps on top. Just long enough to connect to the second leaf. Has anyone else seen this?

You can go top or bottom and can vary the length on the bar stock. longer the bar, more clamps required.I use roughly a 12&quot; bar with 2 clamps

Then you won't need to get too wild with the flat stock, etc...just a couple of clamps ahead of the axle will do fine. Pure Stock tested, Pure Stock approved! <<GRAEMLIN_URL>>/biggthumpup.gif

I've got a KILLER set of the Harrell clamps/bars that Big Steve made for us a few years ago (wouldn't pass Pure Stock tech) that we've ran on a couple cars for the vintage look...I'll try and grab a picture for you, as they're identical to the setup found in the magazine, only prettier!

Like I said above, unless you're running something that's gonna get some hook [and a street tire, or even a good Polyglass isn't gonna do it] then just some simple spring clamps will work sufficiently...adding clamps or clamps+bar aren't gonna add any traction, they're just gonna allow you to hold whatever traction you *do* get.

Anyway, pictures of the beautiful pieces from Big Steve, now residing on our '69 Yenko Nova...

Ok, the spring clamps look great - would love a set myself! However, you gotta scotch-brite that drive shaft, and swap out that bird cage on the left spring! What are slicks doing on that car???? <<GRAEMLIN_URL>>/naughty.gif

Like Rob said, they basically keep the traction you have and keep the springs from twisting up like a pretzel, also keep the rear center section from bashing the floor &quot;somewhat&quot;

Thanks Rob. Those look like a nice piece. They also would not be as noticeable as traction bars. That's what I'm looking for.

Thanks Yenko.net
