Or weld.  I think its much less about bolts loosening off than it is holes egging out onder stress.

They are not part of the car if they are not welded? So do brakes need to be welded to the car as well since they're not the part of the car as they're bolted on.

yeah I know what your saying  :yesnod:      but your adding frame connectors to add  rigidity to the carbody shell  , only real way that can be done is welding  them  in , to become part of the car !  
 think of  having a rusted out front or  rear frame rails !!   instead of spot welding / mig  plugging new repoped AMD ones in   , would you use nuts an bolts ? or glue ?  same thing really

Playing Devil's Advocate here... why are people against bolting in subframe connectors yet don't advocate welding the k-frame in place? More concerned with straight line? During hard curves everything in front of the cowl turns to Jello so welding the k-frame to the frame rails would certainly help! I know subframe connectors are the typical "best bang for the buck" modification and will improve the ride/handling of a stock car but, really, if you aren't majorly upgrading the suspension, brakes, and wheel/tire package for competition will you actually ever notice the difference between well-built bolt-in connectors and welded in ones? I fail to see how the method of attachment on a straight rail between two points will affect the overall rigidity. Now, the full contour connectors are a different story.

Troy
Sarcasm detector, that's a real good invention.

Ghoste

Because you do sometimes have to remove the K-member.  Also I think the debate has largely been about which method was better, bolting in or welding.  If you asked the same question about the K-member I suspect you would find the same results.

Troy

When do you "have to" remove it? The engine can come out the top if necessary and everything else is bolted on to it.

I just like asking because it seems like the answers you get on the internet almost always favor the hardest, most expensive, highest performing, etc. way of doing things. For the average guy who just wants to take the car out for a leisurely cruise a couple times per month I think it can be overwhelming to hear that they need to spend a pile of cash, lots of time, and/or need a bunch of special tools just to improve their ride. For many, many years guys drove with stock suspension parts (possibly with the exception of C-body tie rod ends), drum brakes, wheels with poor offset, junk headers that hung too low, and painted cars in the back yard with single stage. My first 68 only had after market wheels and side mirrors and I managed to drive it daily for 5 years. I had never heard of sub frame connectors and I doubt they would have made much difference with my 318, auto trans, Daytona radials, and 10" drums. If I had installed them, I may have felt some improvement BUT would I have noticed a difference if I had welded instead of bolted?

Hemi swap, concours resto.  Those are two that spring instantly to mind.
The k member likely moves less than the rest of the front end components but yes, welding it in would definitely make it more rigid for the same reasons welding in a sub frame connector makes it more rigid.  
As for my personally wanting to have the connector welded more than I would the k frame, I would be adding the sub frame connector for no other purpose whatsoever than to stiffen the chassis.  My k member is already there serving a dual purpose and though I could weld it in, there are other areas in the front I would go after first.  For an all out car, I would likely weld it too.

Dino

I like the bolt on ones, I think I will order a set!  If my car was a resto then I would weld them in place, but at this moment it is not an option.  The car can be driven absolutely fine without any modifications so the frame connectors are only there to help take the load, not to protect the frame from collapsing.  I believe a dab of panel glue between the frame and connectors and some grade 8 bolts with nylocks or loctite will do just fine.

I thought all the subrame connectors did is tie rear and front torque boxes together so there wouldn't be so much chassis flex.

I don't consider installing sub frame connectors (whether bolt in or weld in) the hardest, most expensive, ect. way of stiffening the chassis.  It's more or less just a band aid fix.  If you want the hardest and most expensive, you'd be replacing the rockers and adding x bracing.  If the rockers were sufficient enough, you wouldn't need sub frame connectors to begin with.

If you aren't welding in your sub frame connectors in, why bother putting them in?  You aren't getting the full benefit of them.

yeah  , welded K frame would be best , infact Grandnational stock cars had a welded on K frame I believe ,
 if they were welded on at the factory , think it might have slowed the  cars assembly down a lot , ie cant have a sub assembly of motor suspension  built up to drop the body over   :yesnod:

Me to! It's just extra beef. There is no debate about "better" it's about each owners choice. I don't drag race, dirt track or drift. Is it better to bolt them in rather than not have any, I think so. Do I need a six pack or sure grip, not really but I got them, because I like having them. How many of us really constantly flog our cars to the limits so bad that only welded in place connectors could make any real difference? Why is it every single time sub frame connectors are brought up it turns into a weld issue? The subject of this topic is "Bolt in frame connectors" NOT Weld, weld isn't mentioned, it was injected into the topic and now is overriding the entire thread.
  Troy is brilliant, why not weld in the K frame? Hell gusset, bracket and over plate the entire chassis and all interconnections.  :scratchchin:   

Ghoste

Its been a useful debate though.  To me, if you don't think your driving necessitates welding them in over bolting them then I don't think you need them at all.

b5blue

  Don't get me wrong, I respect everyone's opinion and position. The factory fix was the torque boxes that tied the subs to the rockers. Knowing my Charger inside and out with my particular plans for repairs and use bolt in makes perfect sense.
A: My car is intended for daily use. B: At some point the trunk area, rear quarters and rocker areas may get repaired/overhauled. C: By bolting in connectors they can be removed if needed for other repairs/concerns but will still help to stiffen the entire chassis.
  I may be fairly unique here as my Charger isn't a restoration project it's my car, for most of the 18 years I've owned it, it's paid for it's keep. My investment in it, money spent for repair has been paid back getting me to work and around town, helping me pay my bills and raise my 3 kids.
  I've hung on to it by only doing what's needed, when needed, I can still jack up any area for any repairs and the doors still open and close just fine, the chassis is solid. The 60's and 70's B Body platform is a remarkably rugged, infinitely repair/rebuild-able automobile. I like the size, road manners and simplicity of repair to the whole package, I see no need for some other car to get me around.

My '68 Charger does not have frame connectors.
FWIW, even though my frame connectors are bolted in my '69 (with a dab of panel bond for added strength), the difference between the two is night & day. I can definitely feel the body is more rigid. How much more rigid it would be if they were welded I do not know, but there is a noticeable difference.

If you had my car and drove it all the time, would you add the bolt on connectors?  I would use the adhesive as well.

Uh, "concourse" would exclude welding anything at all - and subframe connectors completely. Plenty of people have installed Hemis from the top. As a matter of fact, I bet very few Mopar owners actually install the engine from the bottom. The number of them that I know personally is in the single digits - and 4 of those are professional shops.

This is kind of where I was going. Someone certainly can/will notice the addition of connectors but, driving like a normal person, would they even notice the difference if the connectors were welded?

I hear arguments over the technology in skis, snowboards, softball bats, tires, mountain bike frames/suspensions, computer parts, truck shocks, and on and on from people who use their equipment at about 40% of its capacity. None of those minute details matter unless/until you're near the limit. If someone claims that composite bats are better than wood there's hardly any argument that can be made (similar to sub frame connectors vs none). However, the difference between two competing brands of composite bats may only be felt by elite players. The average guy who gets excited when he gets a ball past the pitcher will never know. I guess this is pretty much bench racing - for all manner of activities.

Do you have a welder? Bolt them in. You will definitely notice the difference. You can always weld the bolted connectors when you get to it. You just can't go with the full weld-in type (US Car Tool etc.) in stages like that.

If you are not worried about originality then go for it. I felt it was worthwhile due to the suspension/steering upgrades.
If the underside was not already painted I would have bolted & welded them in. But, the bolts/adhesive combo seemed like a viable substitute, at least better then just bolting them in alone.

No welder here nor am I able to take on that job in my garage so it's bolt in or nothing.  When resto time comes around I may weld the bolt in ones or remove them and get the floor fitted type, but we are talking 5 + years away.

Thanks gents, I will be ordering a set of these.  Any holidays coming up for a discount?   :lol:

Hey, you asked when you would have to remove a k frame so I gave you a couple of examples.  Never mind what side the engine was installed from, how many restoration shops leave the k frame in for painting or while its on the rotisserie?  Some do, some don't.  You never asked me about numbers, you asked when it would ever be removed again and on some cars the fact is that it does sometimes get removed whether it was actually necessary to or not.
But we are in total agreement on one thing, its become more or less a bench racing topic now and us splitting hairs over a definition won't change it.
