Frequently Asked Questions About Peterbilt 567/579 Hub Adapters

Will these hub adapters fit my specific Peterbilt 567 or 579 model year?

Our hub adapters are designed to fit Peterbilt 567 and 579 models from 2013 to present. However, there are variations between early production years (2013-2017) and newer models (2018+) due to slight hub design changes. Before ordering, check your truck's VIN and confirm whether you have the standard 10-lug hub pattern (285.75mm or 11.25" bolt circle) or the metric 10-lug pattern (335mm). Most adapters are universal for both patterns, but double-checking ensures proper fitment.

What material and finish options are available, and which holds up best against rust?

Hub adapters typically come in three main options: chrome-plated steel, polished stainless steel, and powder-coated aluminum. Chrome-plated steel offers a mirror finish at a lower cost but requires regular maintenance to prevent pitting and rust, especially in winter climates with road salt. Polished stainless steel (304 grade) provides the best corrosion resistance and maintains its appearance with minimal upkeep. Powder-coated aluminum is lightweight and rust-proof but may show wear around the lug holes over time. For maximum durability in harsh conditions, we recommend stainless steel.

Do I need any special tools or additional parts for installation?

Installation requires basic hand tools including a lug wrench and torque wrench. You'll need to torque the lug nuts to manufacturer specifications (typically 450-500 ft-lbs for aluminum wheels, 600-650 ft-lbs for steel wheels). No additional parts are needed if you're using your existing lug nuts, but we recommend checking their condition and length. The adapters add approximately 2-3 inches of thickness, so ensure your current lug nuts have adequate thread engagement (at least 1.5 times the diameter of the stud). Some customers opt for extended chrome lug nut covers for a finished appearance.

How thick are these adapters, and will they affect my wheel alignment or tire clearance?

Most hub adapters range from 2 to 3 inches in thickness, which does push your wheels outward by that amount. This additional offset typically doesn't affect alignment but can impact tire clearance, especially if you're running wider tires or have aftermarket fender flares. Before installation, measure the clearance between your tire sidewall and any suspension components, brake lines, or fender edges. You'll need at least 1 inch of clearance to account for tire flex and suspension travel. The added width can improve stability but may require fender adjustments on some configurations.

What's the weight rating on these adapters, and are they DOT approved?

Quality hub adapters are engineered to match or exceed your truck's GAWR (Gross Axle Weight Rating). Most adapters for Peterbilt 567/579 models are rated for 12,000-20,000 lbs per axle, depending on the specific product. While hub adapters themselves don't require DOT certification, they must not compromise your vehicle's safety standards. Look for adapters that are precision-machined with proper weight ratings stamped or documented. Avoid universal or one-size-fits-all adapters that lack specific weight ratings, as these may not meet the load requirements for commercial applications.
