1/2" Hub-Centric Wheel Spacers, Pair | 2001-2026

Merchant Automotive 1/2" Hub-Centric Wheel Spacers move the wheel out half an inch on single rear wheel Chevrolet Silverado and GMC Sierra 2500HD/3500HD trucks. Use them for extra clearance between the wheel and brake calipers or suspension parts, or to fill out the wheel well for a wider stance. Because they're hub-centric, the spacer centers on the hub and the wheel centers on the spacer, so the weight rides on the hub instead of the lug studs. Each spacer is drilled for both 8 on 6.5" (8 × 165.1 mm) and 8 on 180 mm bolt patterns, so the same pair fits 2001–2010 and 2011-up HD trucks. Sold as a pair. Not for dually (dual rear wheel) trucks.

Key Features

• 1/2" (12.7 mm) thick
• Hub-centric design centers the wheel on the hub
• Drilled for both 8 on 6.5" (2001–2010) and 8 on 180 mm (2011–2026) bolt patterns
• Sold as a pair, for one axle
• 2-year warranty

Benefits

• The hub carries the load, not the lug studs, which helps prevent vibration
• Adds clearance for aftermarket wheels, big brakes or suspension components
• Pushes the wheels out for a wider, more aggressive stance
• One part number covers both GM HD bolt patterns

Installation Note

Wheel studs may need to be trimmed so the wheel sits flat against the spacer. Make sure you have full thread engagement on the lug nuts, and re-torque the lug nuts after the first 50–100 miles. Not recommended for dually trucks, because the lug studs are generally not long enough to use a spacer.
