1.5 in 6x5.5 Wheel Spacers for Chevy Silverado GMC Sierra - Durable

In this review the Dynofit 1.5 in wheel spacers are evaluated for owners who want a reliable way to widen track width and improve stance on Chevy and GMC full-size trucks and SUVs. The single biggest reason to buy is the forged, hubcentric design that maintains tight hub contact and uses hardened ISO 10.9 bolts for strength, which should reduce vibration and increase safety compared with many cast or universal spacers.

Key Features

• Fitment: Direct compatibility with a wide range of Chevy and GMC models means owners of Silverado 1500, Sierra 1500, Tahoe, Yukon and related vehicles can expect correct bolt pattern alignment.
• Material: Forged 6061-T6 aluminum billet and CNC machining provide a precise horizontal surface and center lip that helps ensure a hubcentric fit.
• Hardware quality: Heat-treated, hardened ISO 10.9 grade bolts and M14x1.5 studs are supplied to give strong clamping and resist shearing under load.
• Thickness: The 1.5 in (38mm) thickness per spacer gives measurable track widening while remaining within a practical range for many wheel/tire setups.
• Hub bore: A 78.1mm bore centers the spacer on the vehicle hub to minimize runout and reduce the risk of vibration when properly fitted.
• Set size: Sold as a set of 4 pieces to outfit one vehicle axle for balanced fit and appearance.

Who It's For

This product is best for owners of 1999-2025 Silverado 1500, 1999-2025 Sierra 1500, 2000-2025 Yukon, 1999-2025 Escalade and the listed Tahoe, Suburban, Avalanche and Express/Gavana 1500 model years who want a hubcentric, forged spacer for a more aggressive look or improved track width. It suits DIY installers who are comfortable confirming bolt pattern, hub bore and thread pitch before installation.

Drivers seeking maximum clearance for oversized tires or complex suspension lifts should verify clearance and rubbing resistance for their specific wheel and tire combination; some users report mixed results on vibration and rubbing, so those needing a guaranteed no-vibration outcome in every setup should consult a wheel/tire professional first.

Pros & Cons

Pros

• Forged 6061-T6 construction and CNC machining deliver a precise, hubcentric fit and durable material.
• ISO 10.9 hardened bolts and correct M14x1.5 stud threading increase strength and reliability under load.
• Wide vehicle fitment list covers many Silverado, Sierra, Tahoe, Yukon, Suburban and Escalade years for easy selection.
• Set of four spacers completes an axle installation and improves stance and appearance.

Cons

• Some customers report vibration or rubbing in certain wheel/tire combinations, so fitment validation is important before purchase.
• Thickness may not solve extreme clearance issues for heavily lifted builds.

Our Verdict

The Dynofit 1.5 in 6x5.5 wheel spacers are a practical, well-made option for Chevy and GMC full-size truck and SUV owners who want a stronger, hubcentric spacer than many cast alternatives. When matched to the correct hub bore and wheel setup they offer good value for improved stance and reliable clamping, but buyers should double-check clearance and be aware that a small number of installations reported vibration or rubbing.

Frequently Asked Questions

Will these spacers fit my Silverado 1500?
If your Silverado 1500 falls within the listed model years (1999-2025) and uses a 6x5.5 (6x139.7mm) bolt pattern with a 78.1mm hub bore and M14x1.5 thread pitch, these spacers are designed to fit.

Do the spacers come with bolts?
Yes, the set includes ISO 10.9 grade hardened bolts and M14x1.5 studs intended for secure installation.

Will these cause vibration?
Most installations using correct hub centering report no vibration, but a minority of users have reported vibration or rubbing depending on wheel/tire combinations; proper hubcentric mounting and torque are essential to minimize risk.
