A direct replacement extreme duty Tie Rod and Drag Link assembly to replace your underperforming OE steering. 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 (2017-2025) 4WD (except wide track)
- Ford F350 Super Duty (2017-2025) 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
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: 2017 Ford F-350 Super Duty King Ranch, 2017 Ford F-250 Super Duty King Ranch, 2017 Ford F-250 Super Duty Lariat, 2017 Ford F-350 Super Duty Lariat, 2017 Ford F-350 Super Duty Platinum, 2017 Ford F-250 Super Duty Platinum, 2017 Ford F-250 Super Duty XL, 2017 Ford F-350 Super Duty XL, 2017 Ford F-250 Super Duty XLT, 2017 Ford F-350 Super Duty XLT, 2018 Ford F-350 Super Duty Limited, 2018 Ford F-250 Super Duty Limited

Does help, but needs constant adjusting during walk
I watch so many Cesar television shows on how to correct dog behavior and see him use a Yellow version on the shows. I see there is not a yellow version of this lead available on the site so that was irritating because I wanted to get what he uses exactly from his show. Anyway, thanks to another reviewer, I knew to buy the "large" size of this for my 40lb dog because she made the mistake of buying the regular smaller size this site defaults to choose. The "large" is not very long, only 2 ft but maybe the rope is thicker.
The rope is a light stretchy material so it does not chafe your hand, but it still burns after a while of your dog pulling and you trying to keep it from pulling. I could not imagine trying to use this on a dog bigger than 40 pounds because it feels like it is at it's max strength when I am dealing with mine.
My dog likes to eat anything and everything on the ground as we walk so I needed this for the option of the muzzle control feature of the rope. As others have said it acts like the gentle leader halter.
Pros: The adjustable slide to "secure" the loop size over your dog's head, behind it's ears is easy to move up and down.
The black metal ring works well when you use the second circle to loop over your dog's muzzle. Every time she tries to open her mouth to eat something on the ground she can't.
CONS: The adjustable slide to "secure" the loop is too easy to move and therefore I have to constantly push it back down on my dog's head while walking. I am trying to find a clamp of some sort I can clip behind this slider to keep it in place once my dog starts moving.
As soon as it begins to slide up from movement, causing the neck hoop opening to widen and she is back to pulling hard.

Such a great tool!
Size: 48" One Size Fits Most, Color: Black
I have had this product for a week, and I have nothing but good things to say about it! I debated for a couple of days as to whether or not to purchase it because the price seemed a tiny bit much for what looked like such a simple item. Now I know it’s that very same simplicity that makes this such an effective tool! Best money I could have spent on my dog!
I’ve had my rescue Patterdale Terrier for a little under 3 months and I have quickly found out he is far from being perfect. It has taken a lot of time to begin working on correcting some of his problems, one at a time. Like many dogs, he also pulls when being walked. So what did I do as a regular person in need of quick dog tips? I searched up Cesar Millan videos on YouTube. 😂
I had purchased a Flexi leash two weeks after adopting my dog, and he broke it within another two weeks. While it was disappointing when I first found out, I now see it as a blessing in disguise. Paying close attention on YouTube, I noticed common features in all of the videos where the owners had pulling problems. Most owners in these videos had Flexi leashes, and the dog is always walking in front of the owner, not besides them. All Cesar uses to start making a change are leads just like this one. He never explicitly promotes his lead on his show, but after seeing the immediate increased control using such a simple tool, I decided to look online and found this. So I figured, why not?
My dog is 28lbs, so he isn’t big enough to overpower and drag me during a walk. After the Flexi broke, I resorted to using a regular hook-through-the-collar leash. The pulling problem was still there, and would only get worst if we came across a squirrel. As soon as we started using this lead, he’s become much more responsive to my corrections. As soon as he is too far in front of me, even without actually pulling, I give it a quick, gentle tug and a “Chh!” and he‘s learned that he needs to slow down. If he actually pulls and won’t immediately respond to my correction, we’ll sometimes stop walking altogether until he sits, calms down, and realizes that we’ll only walk at my pace. This lead has helped tremendously and there’s rarely ever any tension on the lead when walking now. It’s hard to believe it has only been a week since I’ve started using it, and I don’t believe I’ll go back to using the traditional leash unless absolutely necessary. I would definitely purchase this again!
And no, I have not been paid by anyone, nor was I sent this by any company to review it. Just a regular girl who is so happy to have found something that is actually seeming to work!

Worked from day 1
Size: 48" One Size Fits Most, Color: Black
This leash is the best thing I’ve ever bought for my dog. He’s 1 year and 4 months old, and I’ve bought at least five different harnesses since I got him, including very expensive ones like DogfriendlyCo. He pulls with every single one of them.
I bought this leash a while ago, but I only used it once because I was afraid he would get hyperactive and choke himself. He hated it at first and tried really hard to get out of it. Today, after four months, I decided to give it another try and omg! This is the first time I’ve been able to walk him without feeling anxious or embarrassed. He walked by my side the whole time, and the leash stayed loose. Iwould only pull a little when he wanted to go ahead of me. I could tell he enjoyed the walk and so did I.
I’ve tried it a couple more times just to make sure it wasn’t luck, but this thing really works. Highly recommend.

Only “tough” toy my Doberman loves!
Pattern Name: Octopus
Not indestructible, but last a good long while. Definitely worth the money and lasts longer than any other plush toys we’ve had (which is all my dog will play with). It’s for sure my Dobermans favorite, I’ve ordered probably 10 at this point. He gets the stuffing out after a month or two and we open a new one. He’s picky with toys, either destroys them or ignores them, but he never gets bored with his octopus! 🐙 He sneaks one outside once in a while and the neighbor’s dogs steal it. They love it too and thankfully can’t destroy before I retrieve it.

Great for a Pitball
Pattern Name: Octopus
I have a Pitbull and she absolutely loves this toy. I always wait a while before giving a review. She has had this toy Since the beginning of July and she is still playing with this toy. It does have little holes but it is still going. She loves it. Playing tug of war with her. I also take it and wrap it around her collar and watch her dance around trying to get it out(I don't leave it there long). This a great buy. I also bought and extra one so when this one does finally dies she will have another. The material is strong, The sound is about normal for a squeaky toy.
