2017 Ford F-350 Super Duty Torque Specifications

The 2017 Ford F-350 Super Duty is a massive powerhouse designed to haul, tow, and work hard. Whether your rig is equipped with the 6.2L Boss V8 gas engine or the legendary 6.7L Power Stroke V8 turbo diesel, keeping this beast on the road requires serious maintenance. Due to the high payload and towing capacities, the fasteners on the F-350 are subjected to immense stress. Properly torquing these fasteners is not just best practice—it is an absolute safety requirement.

As an ASE-certified master technician, I constantly see Super Duty trucks in the shop with warped brake rotors, stripped drain plugs, and damaged wheel studs from improper impact wrench use. To help you do the job right, I've compiled this torque specification guide for the 2017 Ford F-350 Super Duty.

Quick reference

Below are the most common torque specifications you will need for routine maintenance and common repairs on your 2017 F-350.

Note: 1 ft-lb = 1.356 Nm. For inch-pounds (in-lb), divide by 12 to get foot-pounds (ft-lb).

Wheel lug torque pattern

The F-350 Super Duty features an 8-lug bolt pattern. Applying 165 ft-lb of torque in the wrong sequence will undoubtedly cause uneven clamping force, leading to severe brake rotor runout (warping) and potential wheel detachment.

Always use a star or cross pattern when tightening 8-lug wheels. Start at the 12 o'clock position, then move across to 6 o'clock, then 10 o'clock to 4 o'clock, 8 o'clock to 2 o'clock, and finally 7 o'clock to 1 o'clock.

1. Snug all nuts with a hand socket.
2. Torque to approximately 80 ft-lb using the star pattern.
3. Finish by torquing to the final 165 ft-lb in the same star pattern.

Brake torque notes

When servicing the heavy-duty brakes on an F-350, pay special attention to the brake caliper bracket bolts. At 203 ft-lb, these require a heavy-duty torque wrench and significant leverage. Do not just "hammer them home" with a half-inch impact gun; an under-torqued bracket can come loose under heavy braking, while an over-torqued bolt can stretch and fail. Make sure the caliper slide pins are torqued exactly to 55 ft-lb to ensure the caliper can float properly without binding.

Why torque matters

Torque specifications are engineered to stretch a bolt just enough to act like a heavy-duty spring, providing optimal clamping force. If you under-torque a fastener on an F-350, the extreme vibrations and heavy loads of towing will cause it to vibrate loose. If you over-torque it, you push the metal past its yield point, permanently weakening the bolt and risking sudden, catastrophic failure under load.

When you are pulling 20,000 pounds down a mountain grade, you need to know with 100% certainty that your brakes and wheels are clamped correctly.

Disclaimer: The specifications provided here are intended as a general reference for the 2017 Ford F-350 Super Duty. Always verify critical fasteners and multi-step torque sequences in the official OEM Ford service manual for your exact submodel, engine, and drivetrain configuration before performing repairs.
