Bora 1 Inch vs 1.5 Inch Wheel Spacers for F150: Which Thickness Works Best for Your Setup?

Stance and Appearance: How Each Thickness Changes Your Truck's Profile

A 1-inch spacer widens your track by two inches total (one inch per side), creating a noticeably planted stance without pushing wheels beyond the fenderwell. This thickness works well if you’re running factory-width wheels or want a subtle improvement in proportions.

A 1.5-inch spacer adds three inches of total track width, moving wheels closer to — or slightly beyond — the fender edge depending on your wheel offset. The wider stance fills out the wheel well and gives the truck a more aggressive, purpose-built look, especially with larger tires or leveling kits.

If you’ve added a lift or leveling kit and want wheels to sit flush with fenders, the 1.5-inch option typically delivers that alignment. Trucks running stock suspension or mild lifts often find the 1-inch spacer sufficient for a balanced appearance without excessive poke.

Clearance and Fitment: Matching Spacer Thickness to Wheel and Tire Size

Clearance issues drive many F150 owners to spacers in the first place, and choosing between 1 inch and 1.5 inches depends on how much room you need. A 1-inch spacer typically clears minor rubbing from oversized tires at full lock or during suspension compression, which is common with 33-inch tires on stock wheels.

A 1.5-inch spacer provides the extra clearance needed for 35-inch tires, wider aftermarket wheels, or setups with high positive offset that would otherwise tuck too far inboard. The additional half-inch can mean the difference between contact and clear rotation, especially if you’re running aggressive tread patterns that extend beyond the rim.

Our 1.5-inch F150 wheel spacers use a hub-centric design that maintains factory alignment while pushing the wheel mounting surface farther out. Measure from your current wheel face to the nearest suspension or body component at full steering lock — if clearance is less than half an inch, the 1.5-inch option gives you the margin you need.

Handling and Steering Feel: How Added Track Width Affects Daily Driving

Widening your track changes leverage on suspension components and steering geometry, and the difference between 1 inch and 1.5 inches is noticeable behind the wheel. A 1-inch spacer improves stability in crosswinds and reduces body roll in corners without adding significant steering effort or changing turn radius measurably.

A 1.5-inch spacer amplifies those stability benefits but also increases load on wheel bearings and tie rods due to the longer moment arm. Most drivers report slightly heavier steering feel at low speeds, though the effect is mild and many consider it a worthwhile trade for the added planted feel at highway speeds.

According to the National Highway Traffic Safety Administration, any suspension modification should maintain safe geometry and load ratings. Both thicknesses work within factory bearing tolerances when installed correctly, but if you tow frequently or haul heavy loads, consider how the added leverage affects wear over time.

Installation and Hardware: What Changes Between the Two Sizes

Both our 1-inch and 1.5-inch spacers use the same 14×2.0 studs that match F150 factory thread pitch, but the 1.5-inch version requires slightly longer studs to maintain full thread engagement. Each kit includes grade-8 studs pre-installed and torqued to spec, so you’re not sourcing separate hardware.

Installation procedure is identical for both thicknesses: remove the wheel, slide the spacer onto the hub, torque the spacer studs to 140 ft-lbs, then mount the wheel onto the spacer’s extended studs and torque to factory spec. The 1.5-inch spacer adds minimal weight — roughly half a pound per corner more than the 1-inch — which doesn’t affect rotational mass noticeably.

Both sizes require periodic retorque after the first 50-100 miles, then again at 500 miles, following the same schedule we recommend across our full lineup including heavy-duty GM truck fitments. After that initial break-in, check torque during routine tire rotations.

Which Thickness to Choose for Your Specific F150 Setup

If you’re running stock wheels and tires or a mild leveling kit with 33-inch tires, the 1-inch spacer typically delivers all the stance and clearance improvement you need without over-widening the track. It’s also the safer choice if you’re unsure about rubbing at full lock, since you can always add a second spacer later if more clearance becomes necessary.

Choose the 1.5-inch spacer if you’ve confirmed rubbing with current fitment, you’re installing 35-inch or wider tires, or you want wheels flush with fenders on a lifted truck. The thicker option is also the right call if you’re upgrading to wider aftermarket wheels and need to push them outboard to avoid suspension contact.

For setups between those extremes — say, a 2.5-inch leveling kit with 34-inch tires on moderate-offset wheels — measure your actual clearance and decide based on real numbers rather than eyeballing. The versatility of Lomax and similar truck accessories often means fitment varies by model year and trim, so confirm your specific configuration before ordering.

Choosing the Right Spacer Thickness for Your F150

The difference between our 1-inch and 1.5-inch F150 wheel spacers comes down to how much stance, clearance, and handling change you’re aiming for. The 1-inch option delivers measurable improvement without drastically altering your truck’s geometry, making it the right choice for mild lifts, stock wheels, and drivers who want a subtle upgrade.

The 1.5-inch spacer is the call when you need maximum clearance for oversized tires, aggressive wheel offsets, or a flush-fender look on lifted trucks. Both thicknesses install with the same process, use the same hardware quality, and deliver the hub-centric fit that keeps your wheels tracking true mile after mile.
