KSP 2 in 8x180 Wheel Spacers for Chevy Silverado and GMC Sierra

Our review of the KSP 2 in 8x180 wheel spacers finds them best suited for Silverado 2500/3500 and Sierra 2500/3500 owners who need reliable hub-centric style wheel adapters to clear brakes, fit larger tires, or achieve a wider stance. The single biggest reason to buy is the combination of forged 6061-T6 aluminum construction and hardened geomet bolts that deliver strength while keeping weight low, producing a solid feel after installation and minimal vibration when properly torqued.

Key Features

• Universal Fitment: Designed specifically for Chevy Silverado 2500/2500 HD/3500 HD and GMC Sierra 2500 HD/3500 HD models that use the 8x180 bolt pattern, providing direct compatibility for those trucks.
• Material and Strength: Forged 6061-T6 aluminum billet construction keeps the spacer lightweight while offering long term durability against road stresses.
• Hardware Quality: Heat treated 10.9 grade geomet bolts and supplied thread locker improve fastening reliability and reduce the chance of looseness or vibration.
• Clearance and Fitment: The 2 in (50.8mm) thickness moves wheels outward to address brake caliper clearance and allow larger tires without rubbing on suspension or bodywork.
• Corrosion Resistance: Black anodized surface treatment adds protection from corrosion for a cleaner long-term appearance on exposed wheel hardware.
• Torque Recommendation: Supplied guidance of 85-95 ft/lbs helps installers achieve correct fastener preload for a secure, wobble-free outcome.

Who It's For

These wheel spacers are ideal for owners of 2011-2024 Silverado 2500/3500 and 2011-2024 Sierra 2500/3500 models that require an 8x180 bolt pattern adapter to resolve caliper clearance, improve stance, or fit wider tires. Enthusiasts who value a strong but lightweight alloy spacer with hardened bolts and an anodized finish will appreciate the build quality.

They are not for users who have a different bolt pattern than 8x180, those seeking hub-centric machines for every application (customer feedback on hub-centric behavior is mixed), or drivers uncomfortable with DIY installation - professional installation is recommended if you cannot confirm torque and fitment yourself.

Pros & Cons

Pros

• High strength forged 6061-T6 aluminum construction keeps weight down while staying durable.
• Hardened 10.9 grade bolts with thread locker reduce the chance of loosening and vibration.
• Two inch thickness provides needed clearance for larger tires and brake calipers, improving stance and cornering stability.
• Black anodized finish improves corrosion resistance and visual integration with wheel hardware.

Cons

• Fits only 8x180 bolt pattern vehicles, so verification of vehicle pattern is required before purchase.
• Some buyers report mixed impressions about hub-centric performance, so careful installation and verification are important.
