dynofit 2-inch Wheel Spacers 6x5.5 (6x139.7) 2-Pack — 78.1mm Hub-Centric Forged Aluminum

Dynofit 2-inch forged aluminum wheel spacers adapt 6x5.5 wheels to your 78.1mm hub, moving wheels outward for improved clearance, stance, and fitment on compatible GM trucks and SUVs. If you need extra clearance for larger tires, want a wider track for better visual stance, or must correct wheel backspacing on GM 6-lug pickups and SUVs, these dynofit spacers are built specifically for that task. Manufactured from 6061-T6 forged aluminum and CNC-machined to hub-centric tolerances, the two-piece set installs between the hub and wheel using M14x1.5 studs and fits a 6x5.5" (6x139.7mm) bolt pattern with a 78.1mm hub bore.

How do these spacers improve tire and brake clearance?

By moving each wheel 2 inches (50.8mm) outward, the spacer increases the distance between the wheel and suspension or brake components. This extra offset helps resolve rubbing on large tires and clears aftermarket brake calipers without cutting or modifying original parts.

• Thickness: 2 inches (50.8mm) adds consistent offset.
• Hub bore: 78.1mm ensures hub-centric alignment for reduced vibration.
• Thread pitch: M14x1.5 studs/nuts match factory fasteners.
• Bolt pattern: 6x5.5" (6x139.7mm) for GM 6-lug applications.

Are these spacers durable and safe for daily driving and off-road use?

These spacers are forged from 6061-T6 aluminum and CNC-finished to maintain dimensional precision and material integrity. Forging improves grain structure and mechanical strength compared with cast parts, while anodizing and machining increase corrosion resistance and longevity under typical road and trail conditions.

• Material: Forged 6061-T6 aluminum for superior toughness.
• Finish: Anodized black surface resists corrosion and wear.
• Hardware: SGS-tested bolts and hardened studs for clamping strength.
• Manufacture: CNC processing ensures tight tolerances and hub-centric fit.

Which vehicles and wheel patterns are compatible with these spacers?

The dynofit two-pack is designed for many GM full-size trucks and SUVs that use a 6x5.5 bolt pattern and a 78.1mm hub bore. Always verify year, make, and model compatibility against the provided fitment list and your vehicle’s factory specifications before purchase.

• Fitment highlights: Silverado/Sierra 1500 (1999–2026) and Escalade (1999–2026).
• Also fits: Tahoe, Suburban, Yukon, Yukon XL, Avalanche, Express/Savana, Savana models where specified.
• Confirm: Year/model compatibility images and vehicle hub bore of 78.1mm.
• Installation: Sold as a 2-piece set for one axle (2 spacers).

How will these spacers change handling and appearance?

Adding two inches of track width gives your truck a more aggressive stance and can slightly improve lateral stability by widening the track. While many drivers notice a firmer feel through corners, handling changes depend on suspension setup, tire size, and driving conditions; spacers are primarily a fitment and aesthetic upgrade rather than a suspension overhaul.

• Appearance: Wider wheel offset produces a flush, aggressive look.
• Handling: Increased track width can enhance cornering stability.
• Tire fitment: Creates clearance for larger diameter or wider tires.
• Note: Re-torque hardware after initial use and follow vehicle safety checks.

Who is this for These dynofit 2" hub-centric spacers suit owners of GM 6-lug trucks and SUVs who need extra wheel clearance, want a wider stance, or are installing larger tires and aftermarket brakes. They are best for mechanically minded buyers or professional installers who will confirm fitment and follow recommended torque procedures; avoid use if your vehicle’s bolt pattern or hub bore differs from the listed specification. Dynofit includes a 12-month after-sales promise — recheck compatibility images and your vehicle details before purchase.
