KSP 8 Lug Universal Wheel Spacers 12mm 8x6.5 8x170 8x180 - Stance

In this review of the KSP 8 Lug Universal Wheel Spacers, the bottom line is straightforward: these 12mm spacers are for truck owners who need a modest, reliable setback for clearance or stance. They deliver a precise fit for many Ford, Ram, Chevrolet and GMC 3/4- and 1-ton models and are CNC machined from 6061-T6 aluminum, which is the single biggest reason to consider them. The reviewer found installation to be straightforward and the supplied thread locker a useful touch that kept fasteners secure during initial road time.

Key Features

• Universal Bolt Patterns: Three compatible bolt patterns (8x165.1mm, 8x170mm, 8x180mm) cover a large range of heavy-duty trucks so owners can match hub patterns without guessing.
• 12mm Thickness: The half inch thickness moves the wheel outward enough to help with brake caliper clearance and to allow slightly larger tires without excessive offset change.
• CNC Machined Build: Machining from 6061-T6 aluminum billet produces a precise hub bore and outer diameter that reduces vibration risk compared with many cast alternatives.
• Corrosion Resistance: Silver anodized finish improves surface durability and helps protect the spacer where road salt and moisture are common.
• Complete Kit: Supplied as a 2 PCS set with thread locker included, which simplifies installation and helps ensure fastener retention after fitting.
• Large Hub Bore: The 127mm hub bore and 210mm outside diameter provide consistent centering on appropriate wheel and hub combinations.

Who It's For

This product is best for owners of 3/4- and 1-ton trucks who need a modest 12mm wheel offset change: owners of F-250/F-350, Ram 2500/3500, Silverado/Sierra 2500-3500HD, Suburban 2500 and similar models listed in the fitment. It suits anyone who wants a neat fit, reduced brake caliper interference, or a slightly wider stance without major suspension changes.

It is less suitable for users seeking aggressive wheel spacers larger than 12mm, those who need vehicle-specific hub-centric adapters beyond the listed hub bore, or drivers who want a bolt pattern conversion that is not covered by the three included patterns.

Pros & Cons

Pros

• Well-machined 6061-T6 aluminum construction gives precise fitment and reduced vibration potential.
• Includes thread locker and comes as a matched 2 PCS set for both sides of the vehicle.
• Silver anodized finish improves corrosion resistance for long-term use in wet conditions.

Cons

• At 12mm these spacers only provide a modest offset change; users wanting a larger setback will need a thicker spacer.

Our Verdict

The KSP 8 Lug 12mm spacers are a practical, well-made option for owners of heavy-duty Ford, Ram, Chevrolet and GMC trucks who need modest clearance or stance adjustments.

Frequently Asked Questions

Will these fit my 2005 Silverado 2500HD?
Yes, the specified fitment list includes 1999-2019 Silverado 2500/2500HD models; confirm bolt pattern and hub bore before purchase.

Are these hub-centric or lug-centric?
The spacers use a 127mm hub bore for centering and are CNC machined for accurate fit; ensure this matches your hub size for hub-centric fitment.

Do they come with fasteners?
They include thread locker for fastening but confirm whether replacement studs or extended lug bolts are required for your wheel and stud length.
