2 in 6x5.5 Hubcentric Wheel Spacer for Silverado Sierra 1500

In this review the Richeer 2 in 6x5.5 hubcentric wheel spacer is evaluated for truck owners who want a wider stance and stronger wheel hardware. Installed on a Silverado or Sierra, the spacer's main selling point is its combination of forged 6061-T6 aluminum construction and Grade 12.9 studs, which promise higher tensile strength and corrosion resistance versus common alternatives. For drivers focused on appearance plus a measurable improvement in track width and handling feel, this spacer is worth considering; those needing custom bolt patterns or exact fitment for nonlisted models should check fit before purchase.

Key Features

• Compatibility: Designed for many Chevy and GMC full size trucks and SUVs, this spacer fits popular models from late 1990s through mid 2020s for straightforward bolt-on use.
• Material and machining: Forged 6061-T6 billet aluminum and CNC precision machining provide consistent thickness and a durable surface that resists corrosion under normal driving conditions.
• High tensile studs: Uses Grade 12.9 14x1.5 studs and nuts rated to about 1000MPa, which increases structural support and reduces risk of stretch compared with softer studs.
• Hubcentric bore: The 78.1mm hub bore centers the wheel on the hub to reduce the risk of runout and help maintain alignment under load.
• Handling benefit: The 2 in spacer increases track width to improve anti-roll characteristics and steering feel in many driving situations.

Who It's For

This spacer is aimed at owners of Silverado 1500, Sierra 1500, Tahoe, Yukon and related GM trucks and SUVs listed in the product compatibility who want a bolt-on way to push the wheels outward for a more aggressive look and improved lateral stability. Enthusiasts who fit aftermarket wheels that need hubcentric support or extra clearance for brake or suspension components will find this useful.

It is not for buyers who need a different bolt pattern, non-hubcentric adapters, or that expect a guaranteed vibration-free result on every wheel/tire combination; a few users report mixed experiences with vibration depending on wheel and hub condition, so those seeking a turnkey, vibrationless conversion on a nonlisted vehicle should look elsewhere or plan for balancing and hub surface prep.

Pros & Cons

Pros

• High quality forged 6061-T6 construction offers solid build quality and corrosion resistance.
• Grade 12.9 studs deliver stronger tensile strength and improved structural support over common 10.9 studs.
• Hubcentric 78.1mm bore helps center wheels and can reduce runout when installed on compatible hubs.
• Provides a noticeable wider stance and more aggressive appearance while improving lateral traction for many users.

Cons

• Fit and vibration results vary by wheel, hub and installation; some users reported excessive vibration requiring further balancing or hub cleaning.
• Only one thickness and bolt pattern are offered, so buyers needing a different offset or pattern must seek alternatives.

Our Verdict

The Richeer 2 in 6x5.5 hubcentric spacer is a strong value for owners of compatible Chevy and GMC trucks who want a bolt-on increase in track width and improved handling feel, backed by high tensile studs and forged 6061-T6 construction. It is a practical upgrade for appearance and stability, but buyers should verify exact fitment and be prepared to address balancing or hub surface issues if vibration appears.

Frequently Asked Questions

Will these spacers fit my 2018 Silverado 1500?
Yes, the spacer lists compatibility through 1999-2025 Silverado 1500 models, but always confirm hub bore and bolt pattern match before installation.

Do the spacers require new lug nuts?
They include 14x1.5 threaded studs and nuts sized for the spacer; check wheel clearance and thread compatibility with your wheels.

Will these eliminate wheel vibration?
They are hubcentric and can reduce runout when installed correctly, but vibration can still occur depending on wheel balance and hub condition, so additional balancing or hub cleaning may be needed.
