61 falcon front coil specs/alternatives

Post #1 by slimjimandtherats » Fri Jun 17, 2016 8:24 pm

I was wondering if someone could fill me in on some specs for a set of original front coil springs for a 61 falcon with 170cid motor. The last owner clipped a few too many coils out, and the ride is abysmal. I've done a fair bit of searching but haven't come up with anything. If anyones found an alternative, i would greatly appreciate the knowledge. Cheers

:hmmm: First off a cut (shorter height) coils are going to be much stiffer than the original taller stock coils. You can generally lower a car about 1 inch without causing trouble with the supention travel. Cutting off more than one coil is a really bad idea. I don't know what the stock spring rate is but many spring companies should be able to tell you that information. If you want to get some custom wound coils that would also lower the car you could try Hellwig in Visalia, Calif. or maybe also Golden West. Good luck :nod:

I am still hunting for a project car to build but with my current low budget it's not looking so good. My Ex- Fleet of Sixes these are all long gone! :bang: 1954 Customline 223 3 speed with O/D, 1963 Fairlane project drag car with BB6, 1977 Maverick 250 with C4, 1994 F-150 a 300 with 5 speed.

In my '60 Falcon with 289 I cut one coil off the Moog 8088 coil springs. They had a load rate of 1540 lbs. I cut two coils off the Moog 8304 coil springs in my 74 Maverick with 250. The firmness of the ride was slight noticeable, but not bone jarring. On a scale 1-10 maybe a 3 at the most. My '06 F150 rides more rough that my Maverick

Here's a coil spring chart showing what came factory in a Falcon. http://1bad6t.com/60-63_Falcon_Coil_Springs.html
My 63 Falcon Futura with 170 came factory with 1460 lbs. load rate

Rad! Thanks 1bad6t. I checked out the grid and it looks like the 6332 has a load rating of 1296lbs with similar configuation as the other two models you mentioned. the original was between 1140-1200lbs. I did see someone mention the 8088 for another build though but im interested in the extra length youd get from the 8304 to dial in my ride height.
Whats mega concerning to me is with the cut coils, the shocks hit the inside of the towers within the hood thus bottoming the front end out immediately. From the research I've done, i would think a shim and alignment would be in order (front tires were rotated to the back and are horribly worn[brand new tread with balding on the inside tread])
Let me know what your thoughts are on those 6332's.
