Three things stand out on this frame that bothers me, one is the distance between the lower control are attachments, wider the better for stability of back and foward movements. Second the rack, for proper steering geometry the pivot on the arms has to be inline or same distance as the centerline of the lca pivot (hard to tell with boot on). Third I don't like the one sided (not double sheer) of the lca pivot bolt either, like I said I've seen the 3/4 bolt that broke on the lca while backing up and turning real slow..
Can't remember the guy but he's a well know writer in the mags that totally downed these k frames, in fact I read his stuff on here years back. Erenburg or something like that.

Ah no. Try again.

A coil over SHOCK, which is exactly what the OP is talking about, is when you combine a spring with a SHOCK, which does NOT replace the upper control arm but works in conjunction with one.

See my comment about you not knowing the difference between a coil over and a McPherson strut. BTW, if you think a McPherson strut setup is better than our torsion bar setup would would be correct in exactly one aspect, cost. In all others it fails.

99% of the aftermarket parts on Our cars have a similar statement. It's the industry standard.

And I guess you're a lawyer...
Regardless, what it DOESN'T say is "THIS PRODUCT IS FOR OFF ROAD USE ONLY" which is what member "Devil" said was disclaimed on "ALL" tubular K frames, which is total BS. This product is ADVERTISED to be used for street use.

Winter came early this year?

How about the best of both worlds? Lighten the factory K and use tubular control arms and coilovers, especially with a motor plate? Been considering this way myself when we drop the stroker in the Charger. Member dvw (Doug) put up some pics of his on FBBO that were nice. I would link to them but can't on my tablet (don't know how).

I’m lazy and I like easy.... the tube k in my race car was a win/win. Makes it so much easier to work on, and the solid feel of the steering I’d have to consider it on a resto-rod type Mopar.

Another “possible” added expense is that custom headers are the cats azz on these set ups!! You can put the tubes where things used to be in the way

I've run an RMS AlterKtion in my 5.7 Hemi Mirada for almost 5 years now, and well over 15000 miles, and I've had no issues with it. It handles significantly better than any available high performance upgrades to the stock suspension that I have driven, and I've tried quite a few. I drive the [censored] out of the car, and it still feels like it did the day I installed it. For me, this was definitely a great investment. Of course, for the A/B/E guys, there are a lot more options, so it's probably more a matter of preference.

383man/Ron,

I cant find the thread but a year or so ago this very same conversation came up. I believe it was White dart(Guessing) that did something with a large bolt thru the lower control arm and added some support in different places to achieve this task. I recall Monte Smith added his two cents and it was positive saying he had done it on one of his many old Mopar's. I will continue to look for it. It can be done for sure on the cheap. I hate it when someone tells me it cant be done, instead of telling me why it cant be done with examples.

all these new front ends are only as good as the guy welding them together. did he do your on Friday after a long lunch?

here is one link, not the one I was looking for, same idea

Thanks again guys for all the replies. Kid Dart thank you for the link as I will check that out. And thanks "I Bleed Mopar" for that info. I was not aware that anyone had used coil/overs while using the factory K-frame as I would love to hear more about that also. I did not start this post for anyone to be fighting with others about it as all replies are cool whether good or bad I appreciate hearing them all. As I said I have not done any aftermarket coli/over K-frames and even when we think we know all about something many times we can find out there is still something we may not have know about. So I do appreciate all the replies and info. Ron

Oh boy , here we go any chance for the journalism major to get his jabs in at RMS ...

Devil , What did Bill do to you that got you a hair across your [censored] over him and his product ?

I run one from HDK. It has been great! Rock solid stable at speed, very adjustable, and parts you can get at your local parts store.

Welcome back, John!

How about the QA1 k frame, looks interesting uses the torsion bars and the strut rods etc.

He's looking to lose the torsion bars because a PO did some cutting and welding around the trans crossmember.


Tim

Oh yeah forgot the t bar mount issue

How about HDK suspension

Member Justadart (Rod) did the front K on Whitedarts (Shilohs) Dart.

Back in the day, the early pro stock-comp cars used a bracket that attached to frame and tb opening when converting to coil overs. They also had bars out there to connect the shock towers so no flexing. Better idea in my view.
Try to find Roy Hills blue Duster, if I remember rite he was running out of Pettys garage then.
They also use the front rack with flipped spindles or lower ball joints.
