KIT375 - Ford F250/F350 17+ - ProLock Steering Kit

Connecting Rod Material* (Pick One): DOM Matte Black Powder Coated Steel
Black Aluminum is Out Of Stock, ETA late November. Steel and Polished Aluminum are in stock.

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 DOM, Polished Aluminum or Black 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 and secured by:

  • Our proprietary jam nuts (which include the extra holding power of 3 set screws threaded into the wrench flats)
  • Our NEW ProLock™washers built into our tie rod and drag link ends

This will change the way your vehicle drives forever!

WHAT IT FITS:

Ford F250 Super Duty (2017-2026) 4WD (except wide track)

Ford F350 Super Duty (2017-2026) 4WD (except wide track)

FITMENT NOTES:

  1. DUAL STEERING STABILIZERS - Due to our tie rod ends being 1/8” larger in diameter than OE, modifications may need to be made to dual stabilizer kit, tie rod end brackets to fit.
  2. 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.
  3. 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
  4. FORD F250/F350 05-07: This kit works with 08+ 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.
  • DuroBoot - The Ultimate Off-Road and 4x4 Boot for Extreme-Duty Steering and Suspension. Made from solid rubber, DuroBoot replaces traditional flimsy dust covers / boots with a rugged solution built for extreme conditions while still allowing full articulation.
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" DOM SAE 1020 Tube: Heavy walled steel tubing provides the tightest most robust steering on the market.
  • Drag Link: 1.75" DOM SAE 1020 Tube: Heavy walled steel tubing provides the tightest most robust steering on the market.
  • Tie Rod: 2.125" 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: 2" 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
  • Our patent-pending ProLock Link Connect System™ is engineered to eliminate one of the most common steering system failures: unwanted tie rod rotation and loosening jam nuts.
  • At the core of the system is a machined keyway integrated directly into the threads of our rod ends. This pairs with a precision-cut keyway washer to create a mechanical lock between the tie rod or drag link ends and the adjusting sleeve—effectively preventing any unintended rotation of the connecting rod.
  • To further secure the assembly, we’ve developed a purpose-built jam nut with integrated set screws. This design positively locks everything in place, eliminating the long-standing issue of jam nuts loosening over time.
  • 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.
  • 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.
  • Our adjusting sleeves are made in the USA

Heavy duty

I waited until I was able to tow with the new parts installed before I gave a review. I can say that my steering way tighter, wheel shimmy is gone. Which is a big deal since I’m running 37’s. Install was pretty easy, redneck alignment sucked, but I got it within 3° which is cool I guess. All in all sweet kit! Way better than factory junk! I did a little install video with no lift, soo the way you are probably planning to do it. https://youtu.be/PtpnK8EgGmI?is=1YLfP097QjfX6h-F

Out standing product

This Apex Chassis steering kit is absolutely insane. Everything about this kit is heavy duty from the tubing to the oversized tie rod and drag link ends. Weather is used for a rig that’s towing, off-roading or even us “street queen” show trucks this is the way to go. Highly recommend this for every application.

Amazing hardware!

I picked up a set for my F350 to upgrade the Moog parts I had, what a massive setup! I am working on getting my truck ready for larger tires (38'') and doing some overlanding in our backroads of Arizona, I feel very confident with these parts not braking on me when I need them the most, get yourself a set, you won't regret it!

Essential Product

On lifted/leveled SD trucks with 35" tires and up this kit is essential. As other reviews have said, this setup is a must if you want a slop free, death wobble free front end. Im not gonna say my truck rides like a roadmaster but for Diesel SD leveled on 35's (Carli Backcountry Level Kit), it rides real smooth. Train tracks, expansion joints, washboards, etc are all no problem. Truck reacts like it's supposed to. No unexpected movement out of the steering wheel. Safe and smooth. Apex parts are HEAVY. Absolutely essential upgrade if you want a solid front end. If you want a sloppy, unpredictable, dangerous SD then don't get this product.

Top notch High quality

If you have a lifted truck or oversize tires this is mandatory equipment. The parts are of excellent quality and design an absolute must have to replace the substandard OEM equipment.

Don’t let the price scare you! Definitely worth the money!!!

I was hesitant at buying the kit first but I said screw it since my tie rods were worn out. These are way beefier and definitely tightened up the steering slop from the OEM setup. You don’t feel every nook and cranny from the roads because these beefy parts absorb it. Highly recommend

These things are seriously heavy duty! The weight is almost scary.

Complete change!

2022 F250 complete steering upgrade.

No questions about it this is the kit for everyone, it simply doesn’t get any better. The feeling of the front end is tight, literally changes the dynamic of how the truck steers.

Remember when you could trust your front end, yeah we’re that comfortable again.
