Safe Stance: The Truth About Wheel Spacers on a 1-Ton Truck
Share
Mention "Wheel Spacers" on a truck forum, and you'll start a war. Half the people will tell you they are fine; the other half will tell you your wheels are going to fall off on the highway.
So, what's the truth for a 2023–2025 Ford F350?
The truth lies in the engineering. The horror stories come from cheap, cast aluminum "Lug-Centric" spacers bought on eBay. These spacers rely on the wheel studs to hold the entire weight of the truck (8,000+ lbs). They vibrate, loosen, and eventually shear off.
However, Hub-Centric Billet Spacers are completely different. They transfer the weight to the hub lip—exactly how the factory designed the wheel to mount.
In this guide, we break down the mechanics of a safe spacer setup. We explain why SRW owners use them to stop larger tires from rubbing the control arms, and why Dually owners strictly need them to prevent their rear tires from rubbing together.

|
Hub-Centric (Billet) |
Hub Lip. Weight rests on the axle hub. |
Maximum. OEM-style fitment; no vibrations. |
SRW Trucks. Adding stance or clearing radius arms. |
|
Steel Dually Spacers |
Hub Lip. Heavy steel construction. |
Extreme. Can handle max towing capacities. |
Duallys. Running 12.50" wide tires on stock rims. |
|
Lug-Centric (Universal) |
Studs Only. Weight rests on the bolts. |
Dangerous. High risk of vibration/shearing. |
Never. Do not use on an F350. |

Slip-On (Shims) |
None. Thin plate (0.25"). |

Minor Tweaks. Fixing slight brake caliper clearance. |
Frequently Asked Questions (Wheel Spacers)
Are wheel spacers safe for towing?
Yes, IF they are Hub-Centric. A high-quality hub-centric spacer becomes an extension of the hub itself. As long as you torque them correctly (and re-torque after 50 miles), they are safe for heavy towing. We recommend Steel Spacers for Duallys hauling heavy 5th wheels.
Will I have to cut my factory studs?
It depends on the spacer thickness and your wheel pockets.
- 2-inch Spacers: Usually clear the factory studs without trimming.
- 1.5-inch Spacers: The factory studs often poke through. If your wheels have "pockets" on the back mounting pad, they will fit. If your wheels are flat on the back, you must trim the unthreaded tip of the factory studs.
Why do Dually tires need spacers?
If you put wide tires (like 12.50s) on a dually without spacers, the sidewalls of the two rear tires will touch. Friction generates heat, and heat leads to catastrophic blowouts. A spacer pushes the outer wheel away, creating the necessary "safety gap" for heat dissipation.
