F40 heavy duty suspension for 65 Beaumonts?

4SPEED427 · A Poncho Legend!

I am guessing it will be only springs and shocks, won't it?

Nothing like the b body with one less control arm on standard suspension, and F40 didn't get you the upper to lower control arm braces did it? I thought those were only on 4 speed cars and I don't even know if the 65 Canadian A body had them did it?

Just checking in the parts book it lists the front and rear springs as being unique to HD suspension.

Frame part number is the same, 64-65

I don't think the extra braces are 4 spd specific because my dads 283 4 spd car doesn't have them but the new red 327 4spd car does. It could be just springs or sway bar thickness? I'm not sure.

4SPEED427 · A Poncho Legend!

There is only one sway bar part number listed for all 64-65 Beaumonts so it shouldn't be any different there.

And of course, no rear bar offered on Beaumont in 65.

Just found that info--

Rear suspension frame reinforcement, group 5.382

3909670 1965/ALL WITH 300 or 350 HP 327 RIGHT
3909669 "" "" "" "" "" LEFT

And then of course, all 1966 and 1967 use the same part numbers as well.

Hey, does that mean all 300 horse automatics use them? Never heard of them on an automatic.

I did notice the 327 car sits a little higher but I assumed that's just newer springs? Seems like a silly option if it's just shocks and springs. I wonder if it was a 12 bolt car that it was standard option? If you got one maybe you got the other?

4SPEED427 · A Poncho Legend!

It sure wasn't that way on the B bodies. There are 283 cars with 12 bolts and standard suspension, which seems crazy.

Do you have documents for this car? I would think it it lists F40 on a document that it is not likely included with any other item but is listed because it's an extra cost.

Just a guess though?

I know F40 was a very common option on country cars in southern Manitoba. All my relatives bought GM cars in the 60's and although the cars were usually base models, they ordered F40.

4SPEED427 · A Poncho Legend!

Well now, here I found something else that might interest you---

Front shock absorber, group 7.345

3192955 1964-1967/ALL

The shocks are no different on an F40 car. Go figure...

I know in 69 the beaumont got the 12 bolt with the standard 350's and 396 engine and F40 option. When you look up F40 option in the 69 info package I got from GM just says shocks and springs but in the chassis section under rear axle includes with F40. Maybe the same for 65 ?

I do mean standard trans.

That explains the 69 Chevelle 350 hardtop in Morris with the 12 bolt under it. Thanks!

4SPEED427 · A Poncho Legend!

No difference in steering box/steering gear ratio although earlier serial numbers use a different box than later for some reason.

65sssd · Poncho Master!

Sounds like the F-40 is the extra bars from the lower trailing arms so far? I have the GM docs for the red 327 4 spd car, it is a F-40 car, and yes the autos have those braces too.

4SPEED427 · A Poncho Legend!

That and different springs appears to be all.

65sssd · Poncho Master!

Is there a reproduction spring that states that it's a F-40 spring?

4SPEED427 · A Poncho Legend!

Not that I'm aware of but there is actually 2 F40 rear springs listed, max load 2431 lbs or max load 2501 lbs. I am pretty sure the aftermarket charts list them so you could match one up.

I have the coil spring books here but I'm off to bed now. If nobody posts up aftermarket spring numbers for you I can do it another time.

******Whoops, edit that top line. It should say 2 F40 front springs listed.******

I have two GM docs that are both 65 4spd cars and neither have a 12 bolt option. The one is a posi, F-40 with a 12bolt, and has extra braces, but the other has no way to confirm if it had a 12 bolt, non posi, and no braces.

4SPEED427 · A Poncho Legend!

Rear F40 springs are listed as being all the same, 194 to 327.

What engines in those 2 cars?

I was told at one time that in the US, all 327 65 Chevelles had 12 bolts.

I guess I could have checked the parts book at the time of that thread and we would have solved this a lot sooner!

Funny how the common misconception is that these are a 4 speed-only part.

kelico · Poncho Master!

my car (283 four speed) had the "boxed" rear trailing arms for a swaybar mount and the heavy duty suspension listed for it as well. of course the arms could have been changed at any point in it's life.. She's been around a bit. LOL

I was told at one time that in the US, all 327 65 Chevelles had 12 bolts.

So the springs in the rear are the same so I wonder about the front? As for the engines, one car is a 283 and the other is a 327. So for Kelly's 4 spd is there any way to confirm if it had a 12 bolt? His car is like my dads but there isn't a F-40 option on my dads car. I'm lost so what stuff does the F-40 get you?
