Oversized tie rod and drag link ends, connected by massive Polished Aluminum adjusting sleeves, eliminates death wobble and tightens up steering under the most extreme conditions. Weak adjusting sleeves are replaced via tie rod and drag link ends threading directly into the connecting rods, secured by jam nuts and our proprietary ninja lock-washers and our New ProLock washers.
This will change the way your vehicle drives forever!
What It Fits:
Ford F250 Super Duty (2005-2016) 4WD (except wide track)
Ford F350 Super Duty (2005-2016) 4WD (except wide track)
Fitment Notes:
- Dual Steering Stabilizers - Due to our tie rod ends being 1/8 inch larger in diameter than OE, modifications may need to be made to dual stabilizer kit, tie rod end brackets to fit.
- BDS Trackbar - Our drag link is not compatible with the BDS Adjustable Trackbar as the adjuster sleeve on the BDS unit will contact the Apex drag link in operation.
- High Mount Steering Stabilizer - Must be mounted in OE position at taper hole in pitman arm side drag link end. We recommend OE style stabilizers from Fox (Part 985-24-001) and Carli (not through shaft stabilizers such as Fox ATS).
- Not Compatible With Wide Track
- Ford F250/F350 05-07: This kit works with 08-Present trucks but for 05-07 will not work with a stock steering stabilizer. You'll need a lower steering stabilizer mount or a dual stabilizer kit. KIT178
The Special Sauce:
-
Housing
- SAE 1045 Solid Steel Forged Housing: This is unequivocally the best carbon alloy steel for this application.
- CNC Machined Housing: Make our parts and bearings dimensionally perfect, eliminating any die wear issues.
-
Ball Studs
- SAE 4140 Hot Forged Chromoly Ball Studs: For the strongest possible metallurgy.
- Induction Heat Treated Ball Studs: Provides a very precise heat treatment to the exact depth and location we want it.
- Rolled Threads: Made by pressing the shape of the threads into the ball stud instead of cutting. This strengthens the threads instead of weakening them and allows for easy movement of hardware. This ain't no Ikea furniture!
- Step Threads: Allows for very easy movement of hardware on install and superior holding when torqued (installer choice).
-
Bearing Design
- Rugged Metal to Metal Bearing
-
Boots
- CR Rubber Boots: The most durable material for undercar applications. Resistant to deterioration from road level ozone, oil/gas/engine fluids and extreme heat or cold.
- Accordion Boot: Ideal for high-articulation components, more flexibility means longer life.
-
Finish
- Polished Aluminum: Highly polished, raw aluminum
- Black Aluminum and DOM Steel: Powder coated black
-
Hardware
- Grade 8 - Class 10.9 Hardware: Superior tensile strength.
- Castle Nut: Industry standard where high vibration loads occur.
-
Adjusting Rods
- Tie Rod: 2.125 inch DOM SAE 1020 Tube: Heavy walled steel tubing provides the tightest most robust steering on the market.
- Drag Link: 1.75 inch DOM SAE 1020 Tube: Heavy walled steel tubing provides the tightest most robust steering on the market.
- Tie Rod: 2.125 inch 7075-T6 Aluminum Rod: The best aluminum available for this application. Extremely durable but has some flex and memory if you really bash it into something.
- Drag Link: 1.75 inch 7075-T6 Aluminum Rod: The best aluminum available for this application. Extremely durable but has some flex and memory if you really bash it into something.
-
Lubrication
- Pre Threaded Zerk Housing: If you have ever installed a MOOG Ball Joint without a pre-threaded zerk fitting you will understand what a simple but great feature this is. Another installer fav.
- Greaseable: Because it should be.
- Pre-Greased: Just in case you forget, we have you covered.
- Gull Winged Grease Grooves: Allows for improved lubrication disbursement around the ball stud.
- Zerk Fittings: Included for every application.
Special Features:
- ProLock Link Connect System (TM): Exclusively from APEX - This patent pending system utilizes a precision keyway cut into the threads of our tie rod and drag link ends, and a pre-bent keyway washer that locks onto the wrench flats of the connecting rod to completely stop any tie rod rotation once the jam nut is set. The jam nut, once torqued to spec, is then locked in place with 3 set-screws inset into the jam nut.
- Pre Bent Ninja Washers (tm): An APEX exclusive is our Ninja Washer which is a unique method of securing the lock nut to the tube, erasing the need for lightly built adjusting tubes with ugly pinch clamps.
- And who doesn't want a ninja on their front end!
- Reversible Drag Link: Another APEX Innovation: In some lifted or aftermarket applications the pitman arm end of the drag link is flipped over causing difficulties with mounting the steering stabilizer into the tapered hole on the drag link end. To solve this we have drilled the hole out straight and provided a reversible stainless steel taper sleeve so the steering stabilizer can be mounted from either side.
- Greaseable, High Articulation Spherical Bushing: For extreme durability our passenger side tie rod is fitted with an oversized greaseable high articulation spherical bushing. This allows for maximum articulation and load disbursement, for better performance, and longer life.
- Minimum Engagement Mark on Drag Link End Threads: If this mark in the thread of the drag link is showing it means you are beyond the safe engagement of threads into the adjusting sleeve. You may be lifted too high and need to switch to a flip kit or you may need to equal out the adjusting sleeve between the two ends.
Fits: 2005 Ford F-250 Super Duty Harley-Davidson Edition, 2005 Ford F-350 Super Duty Harley-Davidson Edition, 2005 Ford F-250 Super Duty King Ranch, 2005 Ford F-350 Super Duty King Ranch, 2005 Ford F-350 Super Duty Lariat, 2005 Ford F-250 Super Duty Lariat, 2005 Ford F-350 Super Duty XL, 2005 Ford F-250 Super Duty XL, 2005 Ford F-350 Super Duty XLT, 2005 Ford F-250 Super Duty XLT, 2008 Ford F-350 Super Duty FX4, 2008 Ford F-250 Super Duty FX4, 2009 Ford F-250 Super Duty Cabela's, 2009 Ford F-350 Super Duty Cabela's, 2013 Ford F-350 Super Duty Platinum, 2013 Ford F-250 Super Duty Platinum

Great Chair
Color: Black, Style: Classic
The durability, recline, noise, fit, and appearance, and stability of the chair were all fantastic. As someone of a shorter height, the backrest which is normally way to high or short for my head fits perfectly. The chair itself is easy to assemble and very comfortable to sit in for long hours. I tend do a lot of work at home and this chair feels very comfortable without feeling the need to get up. The chair looks great set up in my office and is honestly a great office chair. For moving around a room, the wheel guides across my carpet very smoothly with struggling unlike my previous chair which would need a heavy push. Not only that, the chair is noiseless which is a plus for people who get bothered by little sounds when moving around. The fit could honestly fit anyone of any size as the chair itself is quite wide and roomy for me. The seat is also made up of faux leather and feels well stitched and quite durable.

Decent Price
Color: Black, Style: Classic
Chair arrived and was missing critical component so that I could not assemble it. Contacted seller and they sent me a similar component within 2 weeks. Chair was now easy to assemble and very comfortable to use for long periods. Although I wished it could raise another two inches. Also be aware chair might be challenging to get thru a standard 29-30inch doorway but not impossible. Thank You Seller for your help.

Easy installation and comfortable
Color: Black, Style: Classic, Color: Black, Style: Classic
This chair features a premium, quilt-stitched design with thick cushioning that immediately feels supportive. Installation is straightforward — the major components align cleanly, and the hardware fits without forcing, allowing the entire setup to be completed quickly. Once assembled, the chair provides excellent comfort: the padded headrest, wide seat, and soft armrests create a stable, ergonomic sitting experience suitable for long work sessions. The overall build feels solid, and the smooth-rolling casters add to the ease of use.

Seat angle problem
Color: Black, Style: Classic
This chair is very good. Has exactly the dimensions I was looking for. Overall it looks very well made, excellent quality, easy to install. I'm not giving it 5 starts because I'm not liking the angle of the seat very much. It goes low at the back end and at the front it is very high. It feels really good when I'm working on my computer where I have 1 widescreen monitor with 2 smaller ones on top, so it is very comfortable there. But not so much when I'm just working on my desk filling forms and reading papers. I'm actually getting low back pain. I wrote the seller to ask if there is any kind of adjustment I can make but it doesn't look to me like there is anything than can be done. I'm still keeping it.

Most comfortable office chair this fluffy guy has ever sat in.
Color: Black, Style: Classic
This chair is incredibly comfortable—easily the most comfortable one I’ve ever sat in. At around 300lbs, I’ve struggled to find a chair that’s both supportive and spacious. Most options feel tight, with the armrests pressing into my hips. Not this one. If anything, I feel small in it—there’s plenty of room on either side. It’s like going from a cramped budget airline seat to first class on a full-service carrier.
The lumbar support is the best I’ve ever used. The materials are top-notch—everything from the base to the legs to the casters is metal (feels like steel). The casters themselves use what look like inline skate wheels and glide effortlessly across carpet—almost too well on hard surfaces, so you might want to consider a rug. Not a flaw, just something to keep in mind.
I’ve paid twice as much for chairs that felt half as good, so in my opinion, this is an excellent value. The faux leather looks great and the stitching appears durable. While it may not last as long as real leather or high-quality fabric, it should hold up for a reasonable amount of time.
Tilt functionality is basic—just two settings: upright or slightly reclined. Honestly, that’s all I need. If you’re looking for something to nap in, this might not be the chair for you. But for office work or gaming, it absolutely delivers all-day comfort.
For reference, I’m 5'8", and the headrest aligns perfectly with the back of my head. If you're 6'5", it might end up being more of a neck rest.
And I have to give a special shoutout to the included T-shaped hex wrench. It may sound silly, but this alone earns it a 5-star review from me. Every other chair I’ve bought includes those awful angled hex wrenches that make you slam your knuckles into the frame with every turn—often accompanied by some colorful language. Sure, I have my own tools, but finding where my wife hid them isn't always easy. A good-quality tool in the box? That’s thoughtful and appreciated.
