Universal 12mm Wheel Spacers 5x5.5 6x5.5 5x139.7 6x139.7 - Better

In this review the DCVAMOUS 12mm universal wheel spacers are evaluated for owners who need extra clearance or a wider stance without changing wheels. The set of four cast aluminum spacers is aimed at truck and SUV drivers running 5- or 6-lug rims who want to move the wheel out 1/2 in to clear calipers or shocks and gain a more aggressive stance. Install is straightforward for a trained technician, and the primary reason to buy is the reliable material and consistent fitment across many Toyota, Chevy, GMC, Ford and Dodge applications.

Key Features

• Thickness: 12mm or 1/2 in spacing gives measurable extra clearance to prevent wheels from contacting calipers or shocks.
• Material: Cast aluminum construction provides corrosion resistance and a lightweight way to add offset without heavy steel.
• Fitment: Multi-bolt pattern compatibility covers common 5x139.7 and 6x139.7 fits for many trucks and SUVs, simplifying selection for mixed fleets.
• Diameter: 175mm outer diameter with a 108mm center bore keeps the wheel centered while supporting the rim across a broad footprint.
• Stud options: Accepts multiple stud thread sizes including M12, M14, 9/16 in and 1/2 in, which helps match existing hardware.

Who It's For

These spacers are best for owners of older and newer trucks who need a modest 1/2 in offset for clearance problems or to achieve a wider stance. They suit people running common 5- and 6-lug patterns on vehicles listed in the fitment notes, and those comfortable having a professional install the parts to ensure correct torque and safety.

They are not intended for buyers who need very large offsets, custom hub-centric machining, or who prefer a do-it-yourself install without professional support; installation should be performed by a qualified auto shop to avoid fitment or vibration issues.

Pros & Cons

Pros

• Improves clearance for brake calipers and suspension components where a small offset is needed.
• Cast aluminum offers light weight and durable corrosion resistance for long-term use.
• Covers multiple bolt patterns and stud thread sizes for broad compatibility.
