Fitment, Shipping & Product Support
The Apex Chassis KIT372-STL is a direct-replacement extreme-duty tie rod for the 2005–2025 Ford F-250 and F-350 Super Duty 4WD across all three platform generations — P221 (2005–2016), P558 (2017–2022), and P702 (2023–2025). Oversized tie rod ends connected by a massive DOM adjusting sleeve, SAE 1045 CNC-machined forged steel housings, SAE 4140 hot-forged induction heat-treated chromoly ball studs, ProLock™ machined keyway washers, jam nuts with 3 wrench-flat set screws. Matte black powdercoat. One SKU covers all three Super Duty generations. Full front-end alignment required post-install.
Excludes wide track configurations. 2005–2007 trucks require a lower steering stabilizer mount or dual stabilizer kit. Your companion drag link is generation-specific — confirm correct drag link SKU for your year before ordering.

Common Questions
Why does one tie rod fit all three Super Duty generations when the drag link is different?
Ford maintained consistent front knuckle tie rod mounting geometry across P221, P558, and P702 while updating the steering box geometry between generations. The tie rod connects knuckle-to-knuckle — that interface stayed consistent across 2005–2025. The drag link connects the steering box to the axle, and that geometry changed between generations. Same tie rod, different drag links.
My truck is a 2006 — is there anything extra I need?
Yes. 2005–2007 trucks require either a lower steering stabilizer mount or a dual stabilizer kit. The stock stabilizer mounting configuration is not compatible with this tie rod on those early years.
Does this fit my DRW F-350?
Not confirmed in available sourcing. Every authorized source lists standard-track F-250/F-350 without DRW-specific confirmation. Verify before ordering for a dually.
Which drag link do I need with this?
For 2005–2016 P221: order KIT371-BLK or KIT371-POL. For 2017–2025 P558/P702: order KIT373-BLK. Text (469) 407-7538 with your year and we'll confirm the right package.
The Obsidian Take
The KIT372-STL is for the Super Duty owner who wants to sort the tie rod once across any model year from 2005 through 2025. Ford kept the front knuckle tie rod mounting geometry consistent across P221, P558, and P702 — Apex engineered to that consistency with a single SKU that covers all three generations. DOM heavy-wall steel tube, ProLock adjustment retention, Grade 8 hardware.
The drag link is not this straightforward — it's generation-specific, so confirm your companion drag link by year before ordering. For 2005–2007 trucks, budget for the steering stabilizer modification. For everything else, this is a direct bolt-on in a single session with one alignment fee.
