Features & Details

  • Improved Geometry
  • Bolt-In Design
  • Mild Steel DOM Tubular Construction
  • Increased Header Clearance
  • Lighter Than Stock
  • For Off-Road Track Use
  • Fits 1996 to 2004 4.6L V8 Mustangs
Improves Geometry For Racing. This QA1 Racing K-Member has specifically been designed to improve the bump steer, anti-drive and Ackerman angles for maximum performance. This k-member will change your Mustangs stance by moving the front wheels 2" forward to a performance race stance. Because of this fenders and/or fender wells may need to be modified.

Bolt-In Design With Increased Clearance. By digitally indexing all the mounting points from a stock Ford Mustang K-member, this QA1 K-member was designed as a direct bolt-on racing suspension part. The QA1 k-member features increased clearance for both headers and oil pan for easier installation and maintenance.

Tubular Weight Saving Construction. Constructed from DOM Tubular Mild Steel this QA1 Race K-member is up to 28 lbs lighter than the stock K-member and features increased strength and rigidity by design.

Application. This QA1 Tubular Racing K-Member was designed to fit the 1996 to 2004 Mustangs equipped with the 4.6L V8 engine, including the GT, Bullitt, Mach 1 and SVT Cobra. Intended for off road drag race use only.

Technical Note. The QA1 K-Member can be used with stock or aftermarket A-Arms, but for best results, it is recommended to use QA1 control arms.

On 4v motors, does this require an oil filter relocation kit? Car is a 2004 mach1, already has mmr tubular control arms and coilovers on the stock tokico shocks and struts. Almost every other k member I've seen mentions the oil filter relocation kit, except for this one.


  • Relocating the oil filter is not necessary with the install of the QA1 Tubular K-Member (96-04 4.6L).

does this work with a twin turbo setup? i know to put headers and twin turbo setup you have to upgrade the k member for clerance with this be enough for the twin turbo set up and long tube headers?


  • Without seeing exactly how to plan to plumb the turbo systems, there is no way to answer your question with any degree of certainty. That being said, most turbo chargers are mounted on shorty-style headers since long tubes would place the turbos under the car, creating multiple issues. If you're planning to run the rear-mounted system (like STS) this should work fine.

Does this k member come with spring perches?.in the pictures of the item it has a picture of them but it doesn't say anywhere in the description if there required


  • The QA1 Tubular K-Member will include removable spring perches so that these can be used with factory style springs or col overs.

does this k member come with bolts for installation? also, im doing a coyote swap, is this gonna do any worse the process of the swap?


I have a 96 V6 body and a 98 rousch drive train. The 98 K member will not fit the 96 body. Can I use this to start the swap by putting this k member in the 96 body then put the 98 4.6 into it? Thanks.


  • The QA1 Tubular K-Member can be used when swapping the 4.6L into your 96

Will I need to pick up Tubular A arms in order to fit this onto my 99 Cobra? I have heard mixed sources and am just curious. Thank you!


  • QA1 recommends the use of their A Arms with this k member in order to have the best results.

    Very purpose built

    I installed this during an engine overhaul. This K member is exactly what it claims to be, a drag racing component. It is incredibly light and bolts right in. My car launches better, but it feels very unstable cornering. Maybe I need to get used to it, but it feels like the front wheels "settle" mid corner, as if from chassis flex. In order to hook better, some drag racers disconnect the front sway bar and I think this concept factors into the QA1 design. I installed it with factory A arms and Steeda springs. This K member added an additional inch of drop to my all ready lowered car. People have difficulties installing these from what I can tell from the forums. It bolts right in. If you have severe toe issues after installation, know that this widens the track about .75 inches. I ended up lengthening my steering arms by 7 turns (3/8) each to compensate enough to get to the alignment shop. Also, you need caster camber plates to install this. If you get the four bolt, be sure to drill the fourth hole so as to allow the maximum addition of positive camber, otherwise you will not get the full benefit of the alignment job. Also, I changed out whatever long tubes the previous owner had for some new flowtechs at the same time as this install. I don't know if it is because of the new geometry from the K, but I had to dimple the third tube on the driver's side to allow the steering shaft to pass through. Maybe a flowtech problem, but just be carefull , as it will be much easier to test fit then alter the headers before bolting the entire deal up then finding out the steering wont hook (hard lesson). By the way, my stock rims fit at full turn and do not stick out when straight. This is not beyond the backyard mechanic, but you need to know what to expect. This sounds like a lot, but it is very simple in step by step fashion. I think I could do the next one in about three hours. I would not suggest this if you like to corner, but would absolutely recommend it for drag racing.

    not worth it with factory a-arms.

    As of now my cars still at my shop. l'll tell you a few things about this part that bothers me. 1) if using factory a arms, you'be got to grind the a arms. 2) the bracket where the bolt secures the a arm to the k member. The open gap is huge and your factory a arm nuts and bolts won't fit; the nuts are too big and the bolt heads too big to start threading. Big PITA

    QA1 K member is amazing!

    I bought this kit a couple months ago and installed it along with a turbo kit. The k member fits good, although I would recommend taking it to a shop to install, simply because lining up the mounts/ bots does require lots of patience if you don't want to pull the engine out. Great quality, fast shipping and simply an amazing product!

    Made my sn-95 feel like it was new again and if you have longtube headers stick or auto makes the installation a breeze definitely a part to consider for any mustang

    Great product for your money

    Great product but the instructions are not complete if you are using stock control arms you must trim the back of them so they don't rub the k member i would recommend buying the tubular arms and coil overs.

    Great upgrade for your 96-04 4.6

    Bought this for a project I am taking on. I can tell the difference in weight compared to the OEM and is going to make a big difference paired with my aluminum block. Has a great finish and great lightweight sleek design for any Mustang that is going to hit the track.

    A must for a car with headers.

    It makes working on your car so much easier with the room it creates. You have to go to a coil over kit unless you find the lower control arms with the lower spring perch.

    Good for the Money K-Member

    Since I already had Griggs coil-overs and CC plates this installation was quite simple. Especially since my motor is out currently. Overall the quality of the K-member seems good, the welds look to be fine. The weight savings from this should definitely help offset going from an aluminum block to a Boss Iron block. UPS could have been easier on the package during shipping but that's a UPS issue in my area. I am currently very pleased with the purchase and as always with AM's fast shipping. Will update review in about a year to see how this K-member held up. Picture to be uploaded in a few days.
