Default Re: Deuce rear springs

Jim,
By the way, the deuce is supposed to 'sag' in the back, and there are a couple of reasons why a Yenko Deuce would 'sag' a little more than most '68-'72 Novas.

First, the COPO 9737 incorporated 'air-conditioned' part #'d front coil springs into the cars, (this was not part of the F41 package). These springs are not a lot different than the non-ac springs, but were designed for the additional weight of the ac package. Obviously, the weight of the AC package is not on the Yenko Deuce, so the front end will sit a little high.

The F41 package consisted of special heavy duty shocks, another reason, and special sway bars front and rear. When I checked the GM manuals a few years ago regarding the proper ride heights, I found that the F41 cars will sit something like an inch higher in the front, and an inch lower in the back.

Finally, this 'stance' is just how they designed the car. If you look at the original sales brochure, none of the cars are sitting level - much less higher in the back like people restore them to look!

WOW!! Thanks for all the responses. The reason for the concern was at a show last weekend a friend of mine and I were looking at the picture of Cliff Ernst red car and noticed it was sitting more level than mine. I like the look of the Blue one but just thought it might be too low. Everybody asks why it sits higher in the front. Thanks for the answer, Marlin. Thanks to Charlie and Kevin too. At least it shows we have been able to keep a little sense of humor out here.

"Form follows function"

I don't know if Chevrolet intended for it to happen like that, but the rear sitting a little lower than the front helps with weight distribution, and with wheel hop, which we all know leads to lower ETs. You have to remember WHAT the original intent of these cars was !

Marlins point is right on. The cars are a bit nose high. The Yenko Camaros are the same. I have seen all types of ride hights, but your Deuce looks right to me..BKH

I know it looks like the 'grandma' car, but this is way it came!! The weight transfer is 'built in' so to speak, and the rear sway bar helps out, but there is no traction with this car. There seems to be very little travel in the front springs, so there is not much additional weight transfer with the suspension on these Novas.

JIM, I THOUGHT THE SAME THING WITH YOUR BLUE CAR, UNTIL I HAD IT SIDE BY SIDE WITH MY ORANGE ONE. YOU COULD NOT VISUALLY TELL THE DIFFERENCE IN HEIGHT. EITHER THEY ARE BOTH WRONG, OR RIGHT!

Brian,

I don't know if you've seen any of my springs but Ron Normann has been selling them for about a year now and has really good luck with them. We copied an original set of 4 leaves and also have done the 5 leaves. They are EXACT duplicates. Even to the rounded cuts on the spring clamps. The only thing different is we had to use 55-57 Chevy spring insulators and they are 1/4" narrower on each side. Frank Payne
