6x5.5 Wheel Spacers 1 in for Chevy/GMC Silverado Sierra - Better

In this review of the EVIL ENERGY 6x5.5 1 in wheel spacers, the bottom line is simple: these spacers are for truck owners who need a reliable, lightweight way to correct backspacing and gain extra clearance. The reviewer found they deliver a solid fit for compatible Chevy and GMC models and are built from aircraft-grade 6061-T6 aluminum with CNC machining and anodized finish. Installation is straightforward for those familiar with wheel hardware, and the one inch thickness provides a modest track change without causing a rough ride.

Key Features

• Compatibility: Fits a long list of Chevy and GMC models so owners of Silverado, Sierra, Tahoe, Suburban and similar trucks can address clearance issues without wheel changes.
• Material: Machined from 6061-T6 aircraft-grade aluminum to keep weight low while providing durable strength for on-road use.
• Fasteners: Uses 10.9 grade geomet bolts and M14x1.5 threaded studs/nuts to keep the wheel secured and resist common hardware failures.
• Precision: CNC automatic processing and anodized surfaces improve dimensional accuracy and corrosion resistance compared with unfinished spacers.
• Spacer Size: One inch (25 mm) thickness gives a noticeable but moderate stance change that often fixes rubbing and backspacing problems.
• Bolt Pattern: 6x139.7 mm (6x5.5) PCD with 108 mm hub bore for the specified truck hubs.

Who It's For

These spacers are aimed at owners of late 1990s through modern Chevy and GMC 1500/2500 platform trucks and vans who want to correct wheel fitment, clear brake or suspension components, or achieve a slightly wider track. They suit users who plan to keep factory wheels and need a low-profile spacer solution that is machined and anodized.

They are less appropriate for drivers who require hubcentric spacers, as these are not hubcentric and rely on proper torque and wheel centering during installation. Also, buyers who are uncomfortable with wheel removal and re-torquing should seek professional installation rather than DIY.

Pros & Cons

Pros

• High-quality 6061-T6 aluminum construction keeps weight down while offering strength.
• Good hardware with 10.9 grade bolts and M14x1.5 studs provides confidence in fastening.
• Precise CNC machining and anodized finish improve fit and corrosion resistance.

Cons

• Not hubcentric, so careful wheel centering and torque procedure are required.
• One inch thickness is moderate; users needing larger offset changes will need thicker spacers.

Frequently Asked Questions

Will these fit my Silverado 1500?
They are compatible with Chevy Silverado 1500 models listed from 1999 to 2022; double-check year and model before purchasing.

Are these hubcentric spacers?
No, the spacers have a 108 mm hub bore and are not hubcentric, so proper wheel centering and torqueing are important.

What thickness are the spacers?
The spacers are 1 in (25 mm) thick, which provides a moderate offset change to address backspacing and clearance.
