KSP 6x5.5 Wheel Spacers 2 in for Silverado Sierra - Wider Track

In this review of the KSP 6x5.5 wheel spacers, the bottom line is simple: these spacers are aimed at truck owners who want a wider track and a clean, aggressive stance while keeping hub-centric fitment and strong construction. The reviewer found the spacers deliver precise fitment for a long list of GM 6x139.7 vehicles and praised the lightweight yet durable 6061-T6 aircraft aluminum build. Installation is straightforward for anyone comfortable with basic wheel work, and the package includes four forged spacers with studs and thread locker for a ready-to-install kit.

Key Features

• 6061-T6 Aircraft Aluminum: Provides a high strength-to-weight ratio so the spacers add width without excessive unsprung weight.
• CNC Precision Machining: Ensures accurate hole position and professional dimensions for a secure, hub-centric fit on compatible GM trucks.
• Comprehensive Fitment: Designed for 6x139.7 bolt pattern vehicles such as Silverado 1500, Sierra 1500, Tahoe, Yukon and Escalade for wide vehicle coverage.
• Complete Forged Kit: Ships as a set of 4 real forged spacers with ISO/DIN grade studs and high quality SCM435 bolts for durable fastening.
• Black Anodized Finish: Protects against environmental erosion and keeps the visible surface looking clean under road conditions.
• Recommended Torque and Hardware: Comes equipped with thread locker and recommended torque guidance of 85-95 FT/LBS for safe installation.

Who It's For

These spacers are best for owners of 1999-2024 Silverado 1500, 1999-2024 Sierra 1500, 2000-2024 Yukon, 1995-2024 Tahoe 4WD, and other listed GM 6x139.7 models who want improved track width, a more planted look, and the ability to run wheels with more offset without trim interference. Enthusiasts who value precision machining and a hub bore of 78.1mm will appreciate the hub-centric design and forged construction.

Not every driver needs spacers; those who are uncomfortable with wheel removal or who require custom wheel adapters or extreme offsets outside the supplied 2 in may want professional shop support or a different solution. Also, buyers should be aware of the single reported vibration case and confirm hub concentricity on their vehicle before installing.
