I am hoping you guys who have used or is currently using these tubular k-members can chime in and offer some advice. I have a 72 Dodge Charger and Im trying to make a decision on a tubular K-member with rack and pinion.
The Charger is a street/strip car. I've been looking at QA1, Magnum Force, RMS Suspensions/Alterktion and Tory Shellehamer.

Out of these 4 companies currently making tubular k members with rack and pinion steering who has the best proven reputation in regard to strength/durability, overall fit and performance?

Thank you!

You couldn't pay me to install a Magnum Farce front end on a car...

Does Shellehamer make a K member for B bodies? I know he does A body stuff.

Tory does not make a b-body k. He said he can't keep up with the a-body orders. We put the latest AJE k on Larry Boyd's GTX and its working out great.

I have a Alterkation on my Valiant wagon , it is a tried and true setup , I aligned the front , its almost ready to hit the track , everyone likes them ..

I think his communication skills lack a lot , and its not a very fancy looking piece. surprised at all he has made, can't get a mandrel tubing bender .


On my 67 I bought one from Gerst , he was great to deal with , its a nice piece, sold out to qa1 , I can't say if anything changed since that or not .. mine is great

I have an AlterKation in my street/strip Challenger. I like it due to some weight savings, I am able to run a flat bottom 10 qt top fuel dragster type pil pan with plenty of ground clearances. It allowed me to weld up my 4 piece Super Comp Headers up as 1 piece units and they go in from underneath with the engine installed in minutes not having torsion bars to deal with. And, in my case it was all free to me. Long story.

IMO two things to look for, coil over shock support and lower control arm strength-support. My buddy was backing up his car in driveway and sheared off a grade 8 3/4” bolt holding on the lcr. I won’t mention the builders name.

Has there ever been a quantifiable before and after handling test preformed on these kits? I have worked on a charger with complete tubular front and rear suspension. Other than the brake upgrade and possible header clearance is there a handling benefit? I would think upper control arms allowing aggressive alignment specs would do the trick.

Upper control arms for aggressive alignment matched with spring rates, shocks and sway bars

Well, at 138mph, its so smooth its not funny...Try that with a 50 year old OEM front end. Yes, they handle better, drive better, steering is more precise.

AJE front suspension with coil overs, Viking shocks, flaming river rack and pinion. Works real well in my 71 Demon. Not having torsion bars is nice. So much room for activities.

I can think of quite a few OEM front-ends used by members on this site that are a good bit faster with no troubles. Dartin, Alguire, Casey, DVW to name a few.

I made my own K member with rack and Pinion. Uses stock ball joints, Upper and lower arms. Even uses stock torsion bars. Car goes 148mph, and isn't a problem at all.

Seems to me some of those named, run strut cars, and nothing remotely OEM.....But go OEM I don't care, I get no deals on any of the units available. I can tell you, they are a very nice alternative to OEM for a lot of reasons. Including, better drivability.

Next go around, I may even switch manufacturer's just because of the way they designed it and it would help for even more for header clearance than my current two setups.

I agree. Plenty go fast with stock front end. I used to go 150-152mph in the 1/4 with stock front end with no issues. I only changed to the AJE because I felt it was an upgrade. My car is no faster with the rack and pinion front end than the stock front end. I just know I have more room under the car to work, more positive caster, and less Chrysler wobble when the car lands. So if you set up the stock front end right, it will work well.

My dart has been almost 135 with a factory front end with no ill effects or surprises, straight as a string.

My 64 Plymouth is 100% stock front end, rebuilt but all factory mother Mopar, other than the strange brakes. It is smooth as butter at 154mph. Even after its 3' wheelies at the hit. I have had three different folks drive it and they all comment how smooth the car is, like driving a caddy. I also have a strut car and a tube front end car. the 64 is the smoothest by far.

My '63 330 has been 133mph. Same with it. Straight and smooth!

Handling isn't the reason to switch. The factory Mopar setup works better for handling than the coil over and rack setups. The coil over and rack conversions are for space and weight. That is why drag racers convert to coil over and rack, or the higher buck ones go with a strut setup. Corner carvers stay with the factory torsion bar suspension since it works fine up to roughly 150 mph.
