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, eliminate death wobble and tighten 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 (2005-2016) 4WD (except wide track)
Ford F350 Super Duty (2005-2016) 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 the dual stabilizer kit and 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
  5. CLAMPS - DC2.0-Z/DC2.0-B Steel Assemblies; DC2.125-B/DC162(Carli) Aluminum Assemblies.

The Special Sauce:

HOUSING
  • SAE 1045 Solid Steel Forged Housing: This is unequivocally the best carbon alloy steel for this application.
  • CNC-Machined Housing: Makes our parts and bearings dimensionally perfect, eliminating die-wear issues.
BALL STUDS
  • SAE 4140 Hot Forged Chromoly Ball Studs: For the strongest possible metallurgy.
  • Induction Heat Treated Ball Studs: Provide precise heat treatment to the exact depth and location we want.
  • 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 hardware to move easily. 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: In case you forget, we've got you covered.
  • Gull Winged Grease Grooves: Improves lubrication distribution 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 on the drag link end threads is showing, it means you are beyond the safe thread engagement into the adjusting sleeve. You may be lifted too high and need to switch to a flip kit, or you may need to equalize 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, making it difficult to mount 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
