Rough Country 2" Wheel Spacer for GM 1500 (1988–2020) — 6x5.5 Aluminium, Preinstalled Studs

Rough Country 2" wheel spacers widen your truck or SUV track by two inches for improved stance, extra tire clearance, and a more stable ride.

These vehicle-specific spacers are made to fit GM 1500-series vehicles and full-size SUVs from 1988–2020 that use the 6x5.5 bolt pattern. CNC-machined from 6061-T6 aluminum and delivered as a pair with preinstalled studs, they give a durable, drop-in upgrade that reduces rubbing, allows wider wheels or tires, and changes vehicle stance without cutting or modifying factory components.

How will a 2" spacer affect handling and clearance?

Adding two inches of wheel offset increases the track width, which can make the vehicle feel more planted through corners and improve stability in crosswinds. It also creates additional clearance between the tire and suspension or bodywork, enabling fitment of wider tires or aftermarket wheels without rubbing.

• +2" per side increases tire-to-fender distance.
• Improved lateral stability at moderate speeds and during directional changes.
• Reduces need for trimming or rolling fenders when upsizing tires.

Are these spacers compatible with my Chevy Silverado, GMC Sierra, Tahoe, Yukon, or Suburban?

These spacers are engineered specifically for GM 1500 platform trucks and SUVs from 1988–2020 that use a 6x5.5 bolt pattern. Check your truck’s bolt pattern, center bore, and stud thread pitch before ordering to ensure a secure fit.

• Bolt pattern: 6x5.5 (6x139.7 mm).
• Center bore: 3.08" for proper hub engagement.
• Stud thread pitch: M14x1.5 matching factory lug hardware.

What materials and construction keep these spacers reliable?

Rough Country machines these spacers from 6061-T6 aluminum, a high-strength alloy that combines light weight with resistance to fatigue and corrosion. The spacers come with corrosion-resistant finishes and preinstalled studs to simplify installation and help ensure long-lasting service life under road and trail conditions.

• Precision CNC-machined from 6061-T6 billet aluminum.
• Corrosion-resistant surface treatment to withstand weather.
• Preinstalled wheel studs for faster, safer installation.

How straightforward is installation and what should I expect?

Installation is designed to be straightforward for anyone comfortable removing wheels and using a torque wrench. Because the spacers use the factory bolt pattern and proper thread pitch, they seat against the hub and accept your wheel like a factory component; torque values and recheck intervals should follow vehicle manufacturer recommendations.

• Sold as a pair with studs already installed.
• Follow factory torque specs and retorque after initial miles driven.
• No cutting or permanent modification of vehicle required.

Who is this for? These Rough Country 2" wheel spacers are aimed at owners of 1988–2020 Chevy Silverado and GMC Sierra 1500 trucks and compatible full-size GM SUVs who want a wider stance, additional tire clearance, or the ability to run wider aftermarket wheels without major bodywork. They suit drivers who value a proven alloy construction, vehicle-specific fitment, and a simple install backed by Rough Country's limited lifetime replacement warranty.
