I'm not to fond of the way it mounts. Slotted in back pair of holes? Really? I'll keep my stock K.
didn't notice that at first. that just doesn't seem right. a slotted hole for a k-frame mount?
seems like a lot of money to only save 1 pound and still have a stock suspension.
glad they beefed it up though. that cap stuff was scary.

Let's not all jump on the slotted hole bandwagon and give up on this quite yet! Some reasoning behind that opinion would be great. I will also see if can get an explanation for the slotted holes from QA1. Although I think I already know the answer!
Also remember they are still in the semi-developmental phase, so we can still push for some changes.

When they originally started working with the CAP design it was 20lbs lighter. So I think they have done their homework making sure this is a sound unit. I agree, right off, 1 lb of savings might seem questionable. But when you really dig in and look at the whole package, it makes sense. You would have to do a lot of work to an already 40 year k-member to make it similar in strength. Even then, you can't be positive they are comparable. Some welding, gussets, etc, IMHO, not comparable to a tubular engineered design.

Hey guys. I just received the last big box today from QA1. This happens to be the 1st K-member which will be slated to be installed on the car in the next few weeks. Also going on the car will be:
-UCA's
-LCA's
-Adj Strut arms
-(4) double adj shocks
-Torson bar adjusters
-Misc shims and spacers for proper shock fitment
Everything looks very professional as expected. Going to need to wait a few weeks as the car has a few appearances to make, but then we will be moving forward. Hopefully next month we will be on the track for some real feedback.
Keep you guys updated with the progress.
is this a specific 68-70 b body or is this their current ebody version? the e and b bodys have a specific angle difference on the idler mount and the steering box mount....im assuming this is their ebody version....can you please post pics of the steering shaft angle into the box...thanks for sharing looks great...i will order one if it fits well???
#52314
This is the E-body part Number. Currently available. You are correct on the angle difference. Same angle as the 71-72 b-body. This is why they had a slight delay on the 68-70 B-body version, the angles needed some work.
My version I am working with is for the 68-70 B-body.

Regarding your shocks, can you post the part number for the rear shocks? I have double adjustable rears from QA1 (on an E body) and the shock body is too long. With the firm feel road race springs, there is only about 2.5" of compression travel at ride height. Hopefully you will not have the same problems....
I ordered the shocks lengths specifically for what I needed. The ones they list for the front of my car would have been too long. Best thing to do is measure compressed length and then go to their chart and pick the version that best fits your ride height. They can just change the ends to meet your requirements.

I do not like this design. There are no triangles in the geometry or structure -a triangle is the strongest geometric shape. Look at a stock k frame...now look at the latest so called improvement. The K frame is an integral part of a car's suspension and is a major component the overall rigidity of the chassis. Can you say twist??? Having slotted holes on 2/4 mounts is just poor design and the new design looks like it will flex nicely under duress esp with an iron head 440 sitting on it. I would not try this product even if it were free for an A body road course car, let alone a big fat B body Where are the mounts for the right and left side torque rods which experience has shown are required to hold the engine in the correct geometric position at all times??? Do i need to post the photos of the right side collector being pushed to the ground, the compressed engine isolators and the torn exhaust hangers before we figured out the problem?? Back to the million dollar question-how many seconds will this product cut from the current lap times which are btw quite good for a large fat car. This product is in the wrong forum...and i reluctantly post, but it's tough to be spectator when i see products that don't measure up.

dont knock it till its tested...the stock k frame needs to be reinforced in the steering box area cause of flexing when you just turn it at rest...and sector shaft support added...and welded up fully cause of factory spot welds...i think its a great start so far and stronger all around...i would like to see no slots but they are working out the bugs...maybe they will...great price though at 587.00 per summit...by the time you spend shipping back and forth a stock k to firm feel and powdercoating it will be much more.

I have some questions on the new k-frame. How will it hold up to having a floor jack raising the car like you would with a stock unit? Will there be sway bar mounting provisions for the different types of bar[ in front of or through the center]? Can you add on a skid plate? What is the material that is being used? Is it chrome moly 4k series or mild steel 1k series?

If they kick it up a notch and allow for a splined swaybar, that would put it in its own category.
Mopar to the bone!!!

Thanks Tom again for your positive and useful input! I do not think you can look at something and throw it under the bus with '0' factual basis for the criticism, but I have passed these comments onto QA1. I am sure there Engineers at there fully CNC'd, 125,000sq/ft facility will be attempting to cover all these basis.
So you know we are already talking about the torque resolution. I am going to be working on that during the mock up phase.

Swinger,

This is roughly what we will be using. Once the mock is complete, we will be ordering a bar that suits our needs. On this K, the bar mounts are easily accessible in the center area. All you need to do is get the proper roll risistence and order the spline arms to correct cut and you are off and running. To make it really easy for me, I will be ordering the 1½" bar and simply using a 1½" poly mount to secure it to the K. So all you really need are these components:
-1½" Spline bar (around 900-1000 lbs of roll resistence)
-1½" poly mount
-Custom order 1¾ spline arm (or smaller diameter, your decision)
-Hiem/ bolt combination to attach to LCA.
I am pushing QA1 to offer some information in this area because I knew this what going to be a point of contention.
If you are not into adding any extra thought into the bar, then you simply order an 1¼" bar for '70 E-body, bolt it on and go.

This set up will not be for everyone, but it will probably be a popular conversion for a lot of poeple. Looking at my recently received Mancini flyer, the K is being offered at $594, lower arms are $395, upper arms are $304. Add some "dynamic struts for $192, Bilstein shocks for $400, a new Delphi box set up for $1000, and some new t-bars for $300 and you have a tubular K set up for a hair under $3200, or about $1200 less than an AlterK.
Mx and match parts you already have and you can save a few bucks off of that. I predict these will be pretty popular.
