Finding wheel spacers for your 8×170 Ford Super Duty or Excursion isn’t just about looks — it’s about safety under load. With a hub bore that must seat perfectly and lug studs torqued to spec, picking the wrong set can mean wheel separation at highway speed. This guide cuts through the noise to find the sets that actually fit and hold.
I’m Min — the co-founder and writer behind Gadgets Feed. I’ve spent countless hours cross-referencing bolt pattern data, customer failure reports, and material specs to isolate which 8×170 spacers offer genuine strength over marketing hype.
Whether you need to clear brake calipers, mount larger tires, or correct a rubbing suspension, we’ve identified the only sets that balance precise fitment, forged construction, and verified real-world durability for the best 8×170 wheel spacers.
How To Choose The Best 8×170 Wheel Spacers
An 8×170 spacer must mate two precision holes: your truck’s hub bore and the wheel’s center bore. Get the bore wrong, and you get wobble. Get the stud pitch wrong, and the nut won’t seat. Here’s what separates a safe set from a dangerous one.
Hub Bore Match Is Non-Negotiable
Most 8×170 Ford Super Duties (1999-up) use a 125mm hub bore, but some early Excursions and F-250s run a 124.9mm bore. Even a 0.1mm mismatch prevents the spacer from centering, leaving the lug nuts to bear all shear loads. If the spacer is not hub-centric for your specific year, you risk vibration and eventual stud failure.
Thread Pitch: M14x1.5 vs. M14x2
Ford switched thread pitches across model years. 1999-2002 8×170 trucks typically use M14x2 studs, while 2003-up models use M14x1.5. Using the wrong pitch means the nut will either cross-thread or spin loose. Always verify your truck’s lug nut thread before ordering.
Thickness and Stud Clearance
A 1.5-inch spacer on a vehicle with long factory studs may leave the stud tip protruding past the spacer face. That prevents the wheel from seating flat. If you choose a 2-inch spacer, most factory studs sit flush or recessed. Measure your factory stud length before you buy.
Forged vs. Cast Aluminum
Forged 6061-T6 aluminum is the gold standard for wheel spacers. Cast spacers can crack under high torque or heavy towing. Every set we recommend uses forged billet with heat-treated 10.9-grade studs for a predictable fatigue life.

In‑Depth Reviews
1. IRONTEK 8x170mm Wheel Spacers
IRONTEK brings a full set of four forged 6061-T6 spacers with a 2-inch thickness, M14x2 studs, and a 125mm hub bore, designed for 1999-2016 F-250/F-350 Super Duty and 2000-2002 Excursion models. The 28.4-pound total weight reflects the dense billet construction — these are not hollow shells. Customer reports confirm zero vibration after thousands of miles, even with heavy towing and burnouts.
The anodized surface resists corrosion, and the 3-year warranty backs the material quality. The studs are heat-treated 10.9 grade, and the spacers meet SGS fatigue standards. One caveat: the factory studs on some 1999-2002 trucks may protrude past the spacer face, requiring you to either trim the studs or use wheels with open cavities behind the mounting surface.
For owners who plan to tow 10,000 pounds or more, the IRONTEK set removes the guesswork. The 14×2 pitch matches the older Ford stud pattern exactly, and the uniformity across all four corners eliminates the need to mix spacer types. Professional installation is recommended due to the stud clearance consideration.
Why it’s great
- Forged 6061-T6 billet with SGS fatigue certification
- 3-year warranty, rare at this price tier
- Set of 4 ensures consistent track width all around
Good to know
- M14x2 studs only fit 1999-2002 trucks
- Factory studs may need trimming on some models
2. BDFHYK 8x170mm Wheel Spacer
BDFHYK supplies a four-piece kit at 2 inches thick with M14x1.5 thread pitch and a 125mm center bore, covering 2003-2018 F-250/F-350 Super Duty and 2003-2005 Excursion. The aviation-grade 6061 aluminum forging and CNC integrated molding give these spacers a consistent flatness that minimizes runout. The IATF 16949:2016 quality certification adds a layer of manufacturing credibility.
This set is lug-centric, meaning the spacer does not rely on a hub lip for centering — the lug nuts do the alignment work. That makes it ideal for vehicles with custom wheels or aftermarket hubs where the factory lip has been machined off. The included cleaning wire balls and protective gloves show attention to installation prep.
Customer feedback notes the factory studs sit almost flush on 2021 F-150 applications, and several users report successful use on classic Dodge trucks with adapted 8×170 wheels. The 12-month warranty and lifetime after-sales support provide peace of mind, though the non-hub-centric design means you must torque in a star pattern carefully to avoid wobble.
Why it’s great
- IATF 16949:2016 certified manufacturing
- Includes cleaning wire balls and gloves
- Versatile fit for custom and classic conversions
Good to know
- Lug-centric design requires precise torque sequence
- Not hub-centric, so not ideal for stock-only applications
3. VLAOSCHI Forged 8×170 Wheel Spacers
VLAOSCHI uses forged 6061-T6 aerospace aluminum with an anodized black finish, CNC-machined to a 1.5-inch thickness. The 125mm center bore and M14x1.5 studs target 1999-2022 F-250 and Super Duty trucks with the later thread pattern, as well as 2003-2005 Excursions. The 10.9-grade heat-treated carbon steel studs are pre-installed, saving assembly time.
Several customers have logged thousands of miles with heavy payloads and report no lug-nut loosening after the initial re-torque at 50 miles. The 1.5-inch profile pushes the wheel out enough to clear suspension components without causing the excessive bearing load that a 2-inch spacer can introduce on some front ends.
One failure report exists involving studs breaking on a heavy-duty Suburban conversion — but the reviewer noted the vehicle exceeded the spacer’s intended 3/4-ton load rating. For standard F-250/F-350 use, the build quality is consistent. The two-year warranty covers material and workmanship defects.
Why it’s great
- Aerospace-grade forged aluminum with anodized coating
- 2-year warranty against defects
- 1.5in minimizes bearing stress while fixing rub
Good to know
- Not rated for F-350 dually or HD conversions above 1 ton
- Some reports of stud failure under extreme overloading
4. SCITOO 4Pcs Wheel Spacers
SCITOO delivers a four-piece set with a 2-inch thickness, 124.9mm center bore, and M14x1.5 thread pitch, fitting 2003-2022 F-250/F-350 Super Duty and 2003-2005 Excursion. The hot-forged aircraft-grade aluminum is lighter than steel while offering comparable tensile strength. The 124.9mm bore is a precise match for the factory hub on most 2003-up Ford trucks, eliminating the slop that causes steering-wheel vibration.
Customer feedback is split. Several users report excellent fitment on lifted trucks with 35-inch tires, and the 25.2-pound total weight indicates solid material density. However, one critical report documents lug bolts snapping after two months, causing the wheel to separate. That failure may stem from improper torque or using the set on a vehicle with M14x2 studs where the M14x1.5 nuts could not seat fully.
For the price of a four-pack that would normally cost for just two from premium brands, SCITOO is a viable option for low-load street trucks that don’t tow. Verify your thread pitch before installation, and re-torque after 25 miles religiously.
Why it’s great
- Four spacers at a competitive total cost
- 124.9mm bore matches factory hub spec
- Hot-forged aluminum provides good strength-to-weight
Good to know
- Failure reports exist under heavy load
- Must confirm M14x1.5 compatibility before buying
5. Wheel Accessories Parts 8×170 Spacers
This pair of hub-centric spacers from Wheel Accessories Parts measures 1.5 inches thick with a 124.9mm inner diameter, M14x1.5 studs, and a 8×170 bolt pattern on both sides. The 124.9mm ID is engineered to slide onto the factory hub without play. Customer reports on a 2001 F-350 with a 6-inch lift confirm the spacers eliminated tire rub on 35-inch rubber without adding steering wander.
The forging is done on CNC lathes and milling machines to a 0.02mm tolerance, and the black anodized finish provides corrosion resistance. Made in the USA according to the manufacturer, these spacers include SAE 10.9 studs. One review noted the 1.5-inch thickness required trimming factory studs on a 2000 Excursion — a common step for any spacer under 2 inches on older trucks.
Fitment is specifically for 2003-2005 Excursion and 2000-up F-250/F-350 Super Duty with the later thread pitch. The hub-centric design means the spacer centers itself on the hub lip, so lug nuts only need to clamp rather than align. This reduces the chance of vibration compared to a lug-centric design on the same vehicle.
Why it’s great
- Hub-centric for zero wobble on proper hubs
- Made in USA with 0.02mm CNC tolerance
- Eliminates tire rub on lifted trucks
Good to know
- 1.5in may require trimming factory studs
- Only sold as a 2-piece set
6. KSP 8×170 Wheel Spacers
KSP Performance markets these 2-inch lug-centric spacers for 2003-2026 F-250 and F-350 Super Duty, using a 125mm center bore and M14x1.5 thread pitch. The 6061-T6 aluminum billet is gravity-cast rather than forged, which brings the cost down but still offers adequate strength for daily driving. The black anodized surface protects against salt and moisture.
Customer reviews on the 8×170 variant are limited, but the same spacer design in 6×135 fitment has strong feedback for eliminating tire rub on leveling kits. The 10.9-grade geomet bolts resist corrosion, and the 30-day refund with 12-month free replacement policy is straightforward. The recommended torque of 85-95 ft-lbs is clearly stated.
The lug-centric nature means the spacer does not index on the hub lip, so it can accommodate vehicles where the hub diameter has been altered or where aftermarket hubs lack a pronounced lip. However, for a stock 2003-up Super Duty with a clean hub, a hub-centric spacer would offer superior stability. KSP is a solid mid-range option for non-tow trucks.
Why it’s great
- Affordable 2-inch option for 2003-2026 models
- 12-month free replacement policy
- 10.9-grade hardened bolts included
Good to know
- Lug-centric design less stable than hub-centric
- Gravity-cast billet rather than forged
7. EZISOE 2 pcs 8×170 Wheel Spacers
EZISOE offers a two-piece set with a 2-inch thickness, a 130mm hub core, and M14x2 studs, specifically for 1999-2002 F-250/F-350 Super Duty and 2000-2002 Excursion. The 130mm center bore is larger than the standard 125mm, which means these are designed for vehicles where the factory hub has been machined or for aftermarket steering knuckles that use a larger hub diameter.
The forged 6061-T6 aluminum is CNC-machined to a 0.02mm tolerance. Several customers have used these on lifted mud trucks with 40-inch tires and reported no issues after 7,000 miles. However, one critical review states the supplied lug nuts did not fit the spacer studs, causing the nuts to shear off during installation. This indicates possible quality control inconsistency in the included hardware.
At the entry-level price point, this set works best as a temporary fix or for front-axle-only clearance on older 14×2-stud trucks. The 1-year warranty is standard, but the mixed reviews on hardware mean you should test-fit the nuts on the studs before final assembly. Replace the hardware with known-grade parts if any doubt exists.
Why it’s great
- Forged 6061-T6 with 0.02mm CNC tolerance
- Fits 1999-2002 trucks with M14x2 studs
- Lightweight at 12 pounds for the pair
Good to know
- 130mm bore may not fit standard 125mm hubs
- Included lug nut quality is inconsistent
