5x4.75 Hubcentric Wheel Spacers 3 in for Chevy GMC

Our review of these 3 in hubcentric wheel spacers finds them best suited for owners who want a wider stance or need clearance to run larger wheels on older Chevy and GMC 5-lug models. Built from aerospace alloy aluminum 6061 with T6 treatment and precision CNC machining, the spacers come as a complete 2-piece kit with grade 10.9 studs and lug nuts, so installation is straightforward for someone comfortable with basic wheel work. The single biggest reason to buy is the combination of solid material construction and included hardware that delivers a reliable offset without having to source extra parts.

Key Features

• 3 in thickness: Adds 3 in of track width to improve stance and allow larger wheels and tires to clear brakes or suspension components.
• 5x4.75 / 5x120.65 bolt pattern: Matches common Chevy and GMC 5-lug hubs for direct fitment on listed model years when fitment checks out.
• M12x1.5 thread pitch: Uses a common metric stud size so replacement hardware is widely available if needed in the future.
• Center bore 70.5mm: Hubcentric design centers on OEM hubs to reduce vibration when the fit is correct.
• 6061 T6 aluminum: Aerospace-grade material and hard anodized finish resist corrosion while keeping weight lower than steel alternatives.
• Complete kit: Includes grade 10.9 studs and lug nuts so installers do not need separate bolts or adapters.

Who It's For

These spacers are aimed at owners of 1982-2003 Camaro, 1984-2019 Corvette (not compatible with 2020-2022), 1983-2005 Blazer, 1982-2004 S10 and other listed Chevy/GMC models who need extra clearance or a more aggressive stance and who can verify hub and brake clearance prior to purchase. They suit DIY enthusiasts and mechanics who want a complete kit with studs and nuts included.

Those who should look elsewhere are owners of vehicles not listed, drivers with 2WD front hubs on certain S10 and S15 years (not compatible), or anyone unsure about exact fitment without measuring the center bore and stud engagement first.

Pros & Cons

Pros

• Solid construction from 6061 T6 aluminum gives a durable, lightweight spacer.
• Complete installation hardware included, saving a trip to buy studs and nuts separately.
• Hubcentric 70.5mm bore helps reduce vibration when the spacer matches hub dimensions.

Cons

• Fitment is mixed for some customers; the bore can be slightly off on certain front hubs, so verification is required before installation.
• One reported concern about stud strength during aggressive use means careful torque and inspection are advisable.

Our Verdict

For owners of compatible Chevy and GMC models who have verified hub dimensions, these 3 in hubcentric spacers provide a cost-effective way to widen track, clear larger wheels, and improve stance with aerospace-grade material and included hardware. They represent good value when fitment is confirmed, but buyers should measure the center bore and be mindful of stud torque and inspection after installation.
