6x139.7mm Wheel Spacers 1 in Hubcentric - For Silverado Sierra Tahoe

In this review the BDFHYK 6x139.7mm wheel spacers are examined for truck owners who want a wider stance and the ability to run larger tires or aftermarket brakes. The bottom line: these 1 in hubcentric spacers are a practical, value-oriented option for many Chevy and GMC fullsize trucks and vans, offering CNC forged 6061 aluminum construction and a 78.1mm center bore that matches common hubs. They are best for owners who prioritize fit and handling improvements but should be chosen carefully after verifying fit against OEM hub depth and lug specifications.

Key Features

• Hubcentric design: The 78.1mm center bore centers the wheel on the hub to reduce vibration and improve alignment compared with generic spacers.
• Forged 6061 aluminum: Aviation grade forging and CNC integrated molding aim to deliver consistent thickness and durability for safe use on heavy trucks.
• M14x1.5 bolt pattern: The M14 bolts and 6x139.7mm wheel bolt pattern allow direct compatibility with many Chevy and GMC 6-lug wheels listed in the fitment details.
• 1 in thickness set of 4: The 25.4 mm spacer thickness provides modest track width increase to improve stability and create clearance for larger brakes or wider tires.
• Protected finish and hardware: Anodic oxidation treatment and 10.9 class bolts are included to resist wear and help maintain fit over time.
• Accessories and warranty: Protective gloves, cleaning wire balls, and a 12 month warranty with lifetime after-sales service are provided for installation support.

Who It's For

These spacers are aimed at owners of Chevy and GMC fullsize trucks and vans listed in the fitment details who want a straightforward way to widen their track for improved handling or to fit larger wheels and brakes. Enthusiasts fitting wider tires, or those installing aftermarket suspension or brake components that need extra clearance, will find the 1 in thickness helpful.

Those who should look elsewhere include drivers who are unsure about hubcentric fit with their OEM wheels or who need heavier duty adapters for extreme offroad loads. Several customer reports highlight fit and long term durability concerns with lugs on some installs, so professional installation and careful inspection are recommended for heavy towing or commercial use.

Pros & Cons

Pros

• Solid hubcentric fitment with a 78.1mm bore to reduce wheel vibration when matched correctly.

• Wide vehicle fitment across many Chevy and GMC models makes these spacers versatile.

Cons

• Some customers reported lug failures and mixed durability, so long term strength under heavy use is a realistic concern.
