6x139.7 Wheel Spacers 1/1.25/1.5/2 Inch for Chevy Silverado 1500, Tahoe, Suburban & GMC Sierra 1500, Yukon, M14x1.5 Studs, 108mm Hub Bore, Set of 4 | BDFHYK

6x139.7 Wheel Spacers with 108 mm Hub Bore for Chevy and GMC Trucks

These BDFHYK 6x139.7 wheel spacers are built for compatible Chevrolet Silverado 1500, Tahoe, Suburban, GMC Sierra 1500, Yukon, and related 6-lug applications that require M14x1.5 studs and a 108 mm hub bore. They are designed for drivers who need a practical way to adjust wheel position, improve stance, or create additional inner clearance for certain wheel and tire combinations.

This style is a good fitment solution when the wheels sit too far inside the fender line, when a wider tire setup needs more inner room, or when an aftermarket wheel has an offset that places the tire close to suspension or brake components. The spacer moves the wheel outward, but the final result depends on your vehicle, wheel offset, tire width, ride height, and body clearance.

Common Fitment Problems This Spacer Can Help Address

• Factory wheels look tucked: Helps move compatible wheels outward for a wider truck appearance.
• Aftermarket wheel offset is too positive: May help correct an inward wheel position caused by wheel offset selection.
• Tire sidewall is close to suspension parts: Can create additional clearance when rubbing comes from the inner side of the wheel/tire area.
• Need the same spacing on all four corners: Set of 4 supports front and rear installation for a consistent stance.

Essential Fitment Parameters

• Bolt pattern: 6x139.7 / 6x5.5
• Hub bore: 108 mm
• Thread pitch: M14x1.5
• Pack: Set of 4
• Available thickness: 1 inch, 1.25 inch, 1.5 inch, and 2 inch, depending on selected variant

Thickness Selection Guide

The 1 inch and 1.25 inch options are better suited for subtle stance correction or minor inner clearance needs. The 1.5 inch and 2 inch options create a more visible outward wheel position and should be measured carefully before ordering. Always check fender clearance at full steering lock, brake line clearance, suspension compression, and tire movement under load.

What to Measure Before Installation

• Measure the space between the tire sidewall and fender edge.
• Check front wheel clearance while turning left and right.
• Inspect clearance around brake calipers, control arms, sway bar links, and inner liners.
• Confirm that the wheel center bore and lug seat style match the vehicle and hardware.
• Check wheel pocket depth so the original studs do not interfere with the back of the wheel.

Installation Notes

Install only on clean, flat hub surfaces. The spacer should sit evenly against the hub before the wheel is mounted. Use a torque wrench, follow the vehicle manufacturer’s torque specification, and recheck torque after the initial drive. Do not stack wheel spacers, modify the spacer, or install over damaged wheel studs. If the vehicle is used for towing, hauling, or rough roads, inspect the hardware more frequently as part of regular maintenance.
