Carli Suspension Ford Adjustable Track Bar | 2005–2016 F-250/F-350 4WD

Is This for You?

• You're running 2.5"–4.5" of front lift on a 2005–2016 Super Duty and you're experiencing death wobble, axle wander, or steering vagueness — and you've already confirmed the factory rubber bushing track bar is the mechanical source.
• You want a zero-deflection, fully rebuildable frame-end joint — not a polyurethane bushing upgrade, not a heavier tube with the same rubber end, but a 1-1/4" FK Bearing Chromoly Heim with CUB (Captured Uniball Bearing) Joint Technology that eliminates deflection and bind at the root cause.
• You're bolting into the factory frame mount — this bar is engineered for the OEM frame track bar location. If you're running aftermarket track bar drop brackets or a drop Pitman arm, the geometry will be incorrect and this is not the right bar for your configuration.

The Result

• Zero deflection at the frame end — FK Bearing Chromoly Heim CUB joint replaces the factory rubber bushing that deflects, binds, and triggers death wobble on lifted straight-axle trucks.
• Diagonal axle shift corrected — offset machined tapered rod end at the axle end addresses the lateral axle walk introduced by lifting a straight-axle Super Duty.
• Precise, repeatable length adjustment — threaded body with Jammit nut (100% more surface area than standard jam nuts) for centering the axle under the chassis post-installation.

On a factory 2005–2016 Super Duty, the track bar uses a rubber bushing at the frame end. At stock ride height, that bushing operates within its designed deflection range. At 2.5"–4.5" of lift, the bar angle changes, the bushing is placed in a bind position through the range of suspension travel, and under the right combination of speed and road input, that bind releases suddenly — the mechanical trigger for death wobble. The CUB joint replaces the rubber bushing with a 1-1/4" FK Bearing Chromoly Heim in a captured uniball configuration: it articulates freely through the full range of suspension travel, does not deflect under lateral load, does not bind at droop, and can be disassembled and rebuilt at any service interval. The 1.50" OD x 3/8" wall DOM steel tube body is significantly more rigid than the factory hollow-tube unit — it does not flex under the lateral forces a straight-axle diesel generates at speed. The offset machined tapered rod end at the axle end is not a standard rod end — it is machined with a specific offset to correct the diagonal axle shift that occurs when a straight-axle truck is lifted, pulling the axle laterally out of center. The Jammit nut provides 100% more thread engagement surface area than a standard jam nut, maintaining adjustment under vibration and load cycles without backing off.

✔ 2005–2016 Ford F-350 Super Duty 4WD — SRW & DRW

✘ Does NOT fit: Stock height trucks — bar length engineered for 2.5"–4.5" lifted applications only
✘ Does NOT fit: Trucks running aftermarket track bar drop brackets or drop Pitman arms — bolts into factory frame mount only; geometry will be incorrect with drop hardware
✘ Does NOT fit: 2017–2026 Ford F-250/F-350 — different Super Duty platform geometry; see CS-FPRB-17
✘ Does NOT fit: 2004 and earlier Ford F-250/F-350
✘ Does NOT fit: 2WD Super Duty models
✘ Does NOT fit: Ford F-150 — incompatible platform
✘ Does NOT fit: Ram or GM platforms

Installation Notes

• Bolts directly into the factory frame track bar mount. Do not use with aftermarket track bar drop brackets or drop Pitman arms — geometry will be incorrect.
• Adjust bar length until axle is centered under the chassis before final torque. The offset tapered rod end corrects diagonal axle shift — centering is required post-installation.
• Torque frame-end Heim joint to Carli specification. Torque axle-end tapered rod end to OEM taper bore spec. Re-torque at 500-mile break-in interval.
• Full front-end alignment recommended post-installation. Axle centering directly affects caster, toe, and steering returnability.
• Inspect and re-grease FK Heim joint at regular service intervals. Do not allow joint to run dry.
• Install steering stabilizer relocation bracket to ensure clearance for high-mount stabilizer configurations.

Engineering Question: Are you running 2.5"–4.5" of front lift on a 2005–2016 Super Duty and bolting into the factory frame track bar mount — no drop brackets, no drop Pitman arm? Confirm your lift height and current track bar mount configuration before ordering. If you're on a 2017–2026 platform, this bar does not fit — see CS-FPRB-17.
