Product Description – Hub-Centric Wheel Spacers for 6x5.5" (139.7mm) Bolt Pattern – 78mm Bore
These hub-centric wheel adapters are specifically engineered for vehicles with a 6-lug 5.5" (139.7mm) bolt pattern and 78mm center bore. They are designed to allow proper fitment of factory wheels with a matching 78mm center bore. Crafted from high-strength 6061-T6 billet aluminum, each adapter is CNC machined to ensure precision, durability, and an exact hub-centric fit for maximum wheel stability and performance.
Product Specifications:
Bolt Pattern (Vehicle & Wheel Side): 6x5.5" (6x139.7mm)
Center Bore: 78mm (hub-centric)
Stud Thread Size: 14x1.5
Material: Aerospace-grade CNC-machined 6061-T6 billet aluminum

Sold As: Pair (2 spacers)
Compatible Vehicles Include (but not limited to):
Chevrolet:

Yukon Denali / Denali XL (1998–present)
Cadillac:
Escalade (all years with 6-lug configuration)
Why Choose These Spacers:
Hub-Centric Fit: Designed to match the hub diameter exactly, minimizing vibration and ensuring the wheel is perfectly centered.
Superior Strength: Made from aircraft-grade aluminum for a lightweight yet highly durable construction.
Improved Fitment: Ideal for spacing out wheels for clearance, stance adjustment, or brake upgrades while retaining factory wheel compatibility.
Installation Advisory:
Due to the typical 1-inch thickness of these spacers, there may be instances where the vehicle’s factory hub studs protrude beyond the adapter’s mounting face. If the wheel’s mounting surface does not have cavities to accommodate this, the factory studs must be trimmed to ensure the wheel sits flush against the adapter. Proper flush mounting is critical for both safety and long-term performance.
