6x139.7mm Wheel Spacers 1.25 in Hubcentric Set of 4 - Improved Track

In this review of the 6x139.7mm 1.25 in hubcentric wheel spacers, the bottom line is simple: these spacers are aimed at owners of Chevy and GMC trucks and vans who want a wider stance and room for larger tires or brake upgrades without complex modifications. The reviewer found the spacers are well machined from forged 6061 aluminum, come as a set of 4 with gloves and cleaning wire balls, and include M14x1.5 hardware and a 78.1mm center bore to suit many OEM hubs. This review highlights fit, build, and practical tradeoffs so readers can decide if they suit their vehicle and needs.

Key Features

• Vehicle Compatibility: Designed to fit a long list of Chevy and GMC models, making them a practical option for Silverado, Sierra, Tahoe, Yukon and related vans from the model years listed.
• Forged 6061 Aluminum: The CNC forged construction improves dimensional accuracy and wear resistance for consistent wheel centering.
• Hubcentric Design: The 78.1mm center bore keeps the wheel centered on the hub, helping to reduce vibration when matched to compatible hubs and wheels.
• Hardware Included: Comes as a set of 4 with M14x1.5 bolts and 10.9 class fasteners, plus protective gloves and cleaning wire balls to aid installation.
• Increased Clearance: The 1.25 in thickness provides extra space for wider tires, larger brakes, or suspension work without changing wheel offset.
• Warranty and Support: A 12 month warranty and lifetime after-sales service are provided to address fit or manufacturing issues.

Who It's For

These spacers are best for truck and full-size SUV owners who need a modest increase in track width to fit larger tires or improve vehicle stance, and for DIYers comfortable checking fitment against OEM hub bores. They suit owners of Chevy Avalanche, Express, Silverado, Suburban, Tahoe and GMC Sierra, Yukon, Savana when the bolt pattern and bore match the vehicle.

Those who should look elsewhere include drivers who require thicker spacers for extreme offset changes, or people unwilling to verify hub-centric compatibility and torque procedures; some customers report fit and lug durability concerns, so professional installation is wise for critical safety checks.
