1.5 in 5x4.75 Hubcentric Wheel Spacers 5 Lug - Safe Fit and Stability

Our review of these 1.5 in hubcentric wheel spacers finds them best for owners who need a precise 5x4.75 to 5x4.75 adapter that improves wheel fit and stance without changing bolt pattern. The single biggest reason to buy is straightforward: they are CNC-machined from forged 6061-T6 aluminum with a 70.5mm hub bore and 12x1.5 studs, so they center the wheel accurately and reduce vibration when installed to the recommended torque. They suit classic GM models and anyone adapting Corvette wheels to other 5x4.75 bolt patterns.

Key Features

• Hubcentric design: The 70.5mm hub bore centers the wheel on the hub to reduce runout and the chance of vibration when surfaces are clean.
• Material and machining: Forged 6061-T6 billet aluminum and CNC precision machining provide consistent thickness and fit for improved stability.
• Durable studs: 10.9 grade studs with 12x1.5 thread pitch deliver high tensile strength for structural support under load.
• Complete kit: The package includes two wheel spacers and thread locker glue so you have what is needed for installation right away.
• Recommended torque: Clear install guidance of 70-80 ft/lbs helps avoid vibration and maintain a tight wheel-to-hub interface.

Who It's For

This product is aimed at owners of GMC Jimmy 1991-2005, GMC S15 1982-1990, Chevrolet Corvette models listed as compatible, and several classic General Motors cars who need a hubcentric spacer to adapt wheels or widen track. It is useful for enthusiasts who want a straightforward spacer that maintains wheel centering and improves vehicle handling and appearance.

Those who should look elsewhere include drivers who cannot verify their bolt circle, bolt count, hub bore or thread pitch before purchase, or anyone needing a spacer for bolt patterns other than 5x4.75. Also, if you need a spacer thicker or thinner than 1.5 in for fender clearance, pick a different size.
