KSP 1.5-Inch Spacers For GM 6-Lug Vehicles
This four-piece KSP set has a 6×5.5-inch (6×139.7mm) bolt pattern, 78.1mm hub bore, and M14x1.5 studs. The listed fitments include various model years of Silverado 1500, Sierra 1500, Tahoe, Suburban, Yukon, Escalade, Avalanche, Express, and Savana vehicles. Check the exact vehicle year and configuration against the seller’s fitment information before ordering.
The spacers are described as forged 6061-T6 aluminum with CNC machining and black anodizing. The listing also specifies heat-treated SCM435 bolts, Geomet studs, thread locker, and a recommended torque of 85–95 ft-lb. Best for: GM truck and SUV owners whose vehicle matches all listed dimensions. The 1.5-inch thickness may not suit every wheel and fender-clearance setup, so check available clearance.
KSP 1.5-Inch Spacers For Newer Toyota Models
This four-piece set is specified as 1.5 inches thick, with a 6×139.7mm pattern, 95.2mm hub bore, and 14×1.5 lug studs. Its name lists 2023-and-newer Tundra, 2026-and-newer Tacoma, and 2026-and-newer 4Runner, along with Toyota-Lexus six-lug applications.
Best for: Owners of a listed newer Toyota or Lexus vehicle who need this specific pattern and bore. The product name supplies key dimensions, but the provided listing information does not describe material, finish, or installation torque. Avoid choosing it based on vehicle name alone; confirm the exact hub bore, thread, and year fitment.
OMT 5×4.5 Spacers For Select Ford And Jeep Models
Orion Motor Tech’s set of two is listed with a 5×4.5-inch bolt pattern and an 82.5mm center hub bore. The stated vehicle applications include select Ford Bronco, Crown Victoria, Explorer, Edge, Mustang, and Ranger years, plus Jeep Comanche, Cherokee, Grand Cherokee, Liberty, and Wrangler YJ and TJ models.
The listing describes T6 aircraft-grade aluminum spacers and ten heat-treated, zinc-coated 1/2″-20 bolts. It says the spacers add two inches to the axle track. Best for: Buyers whose vehicle matches the listed pattern, bore, and application. The set contains two spacers, rather than four, so check whether that quantity matches the intended installation. Confirm fitment for the specific trim and year.
CMO 25mm Spacers For Nissan And Infiniti
This two-piece, 25mm (one-inch) bolt-on set has a 5×114.3 pattern, 66.1mm vehicle-side bore, 66.1mm wheel-side lip, and M12x1.25 Class 10.9 studs. Listed applications include several Nissan models such as the 350Z, 370Z, Altima, and Rogue, and Infiniti models including the G35, G37, Q50, and QX50. Verify the model year and fitment before ordering.
The listing specifies forged 6061-T6 aluminum, black anodizing, and four-axis CNC machining. Best for: Nissan and Infiniti owners whose hub and wheel specifications match. The seller specifically advises checking fender clearance, offset, and backspacing; the one-inch outward movement may not clear every setup.
1.5-Inch 5×139.7 Spacers For Ram 1500
The supplied product name identifies this as a 1.5-inch spacer with a 5×139.7mm pattern for Ram 1500. Best for: Ram owners who have independently confirmed that the vehicle’s bolt pattern and other required dimensions match the actual product.
The provided product details do not specify hub bore, stud thread, material, set quantity, or exact model-year fitment. These omissions make verification especially important. Do not select this spacer based on the vehicle name and pattern alone; confirm the complete specifications and application before purchase.
Buying Guide: How To Choose Bolt-On Wheel Spacers
Which specifications must match?
Start with the vehicle’s bolt pattern, hub bore, and lug-stud thread pitch. Then check the spacer’s wheel-side pattern and center lip against the wheel. A mismatch can prevent proper seating or centering. Compare the measurements with the vehicle and wheel manufacturer’s specifications, and verify the exact year and configuration.
How much spacer thickness do you need?
Thickness determines how far the wheel moves outward. The products here range from 25mm (one inch) to 1.5 inches, while the OMT listing describes a two-inch increase in axle track. Check clearance at the fender and suspension, including the vehicle’s intended steering and suspension movement. Do not assume that a spacer thickness will work with every wheel offset.
Should you choose forged aluminum?
Some listings specifically describe forged 6061-T6 aluminum and machined surfaces; others provide limited material information. Compare disclosed construction, fastener details, and installation guidance rather than assuming all spacers are made alike. Follow the product’s stated torque instructions where provided, and have installation performed by a qualified professional if unsure.
Frequently Asked Questions
What does a bolt-on wheel spacer do?
It mounts between the vehicle hub and wheel to move the wheel outward. The amount depends on the spacer’s thickness.
Are 5×4.5 and 5×114.3 the same pattern?
They are commonly used as inch and metric descriptions of the same nominal bolt-circle size, but confirm the complete fitment and hub dimensions before buying.
Can I use any spacer with the right bolt pattern?
No. The hub bore, stud thread, wheel-side fit, thickness, and vehicle application also need to match.
Do all products include four spacers?
No. The listings identify some sets as four pieces and others as two. Check the package quantity and intended axle placement before ordering.
What should I check before installation?
Confirm fitment, inspect that mating surfaces seat cleanly and flush, check wheel and fender clearance, and follow the product’s installation and torque instructions.
