5x4.75 Hub Centric Wheel Spacers 1in for Chevy Corvette Camaro & GM

In this review of the 5x4.75 hub centric wheel spacers, the bottom line is straightforward: these 1in spacers are for owners of older Chevrolet, Cadillac, GMC and Pontiac models who want a simple, bolt-on way to push wheels outward for clearance and a stronger stance. The reviewer found the spacers deliver solid construction and hub-centric security, making them a practical upgrade for compatible 5 lug vehicles when fitment is confirmed. They are not a universal solution, so careful checking of bolt pattern and 70.5mm hub bore is essential before purchase.

Key Features

• Hubcentric design: The 70.5mm lip centers the spacer on the vehicle hub so clamping force returns to the hub rather than relying solely on the lugs.
• Exact bolt pattern: The 5x4.75 in (120.65 mm) PCD matches common GM 5 lug applications for a direct fit where listed.
• One inch thickness: Adds 1 in of offset to push wheels outward for clearance, stance, and improved handling balance in many setups.
• M12x1.5 hardware: Includes 12.9 grade studs and lug nuts for high tensile strength and recommended torque of 70-80 ft/lbs.
• Bolt-on installation: Comes as a pair with installation instructions, making it straightforward to install when vehicle hubs and brake components allow the extra 1 in spacing.

Who It's For

This spacer set is aimed at owners of compatible GM cars and trucks listed in the product fitment, including many S10, Camaro, Corvette, Blazer, Firebird, Eldorado, XLR, Sonoma, Jimmy and similar models from the late 1970s through 2019. It is best for drivers who need a reliable hubcentric spacer to improve wheel clearance, achieve a wider track, or fit aftermarket wheels like Z28 style rims that may rub in stock position.

Owners with 2WD front hubs flagged in the fitment notes or vehicles not matching the 5x4.75 bolt pattern and 70.5mm hub bore should look elsewhere. Anyone who cannot verify hub bore or does not have basic tools and torque equipment should consider professional installation.

Pros & Cons

Pros

• Solid hubcentric lip returns clamping force to the hub for a secure fit.
• High strength 12.9 grade studs and M12x1.5 nuts supplied for durability.

Our Verdict

These 5x4.75 hub centric wheel spacers are a practical, value-oriented upgrade for compatible GM vehicles when fitment is confirmed.

Frequently Asked Questions

Will these spacers fit my Camaro or Corvette?
They fit many Camaro and Corvette years listed for the 5x4.75 bolt pattern, but confirm your vehicle year and 70.5 mm hub bore before purchase.

Are hub centric rings needed?
No, the spacers are hubcentric with a 70.5 mm lip so separate hub centric rings are not required for matched hubs.

How tightly should the lug nuts be torqued?
Tighten to the recommended 70-80 ft/lbs and recheck regularly; use a high-strength thread locker if desired for added security.
