📐 Specifications

🔍 Which Bolt Pattern Do I Need?

5 on 4.5" — The most common pattern on utility trailers, cargo trailers, enclosed trailers, landscape trailers, and boat trailers rated under 10,000 lbs. Bolt holes sit on a 4.5" circle. This is the standard pattern on Dexter, Lippert, and most axles rated 3,500–5,200 lbs.

5 on 5" — Used on heavier trailers including larger boat trailers, horse trailers, and some car haulers. Bolt holes sit on a 5" circle. Common on Dexter and Lippert 5,200–7,000 lb axles as well as many larger marine trailers.

⚠️ Using the wrong bolt pattern will prevent proper mounting and create unsafe conditions. Measure your existing wheel or check your axle manufacturer's spec to confirm before ordering.

💪 Key Features

✔ High-Grade Aluminum Alloy

Significantly lighter than steel wheels — reduces unsprung weight for improved fuel economy and reduced suspension wear.

✔ Black Machined Face — 5-Fork Design

Bold glossy black enamel with precision-machined silver accents on spoke edges and outer lip. Steel inserts in lug nut wells prevent stripping and keep the wheel secure on the hub.

✔ Corrosion Resistant

Aluminum construction with gloss enamel coating resists rust, road salt, and moisture — engineered for year-round outdoor use on trailers.

✔ Grease Port Center Cap

The center cap includes a removable center plug providing access to E/Z Lube style grease zerks — no need to remove the wheel to grease bearings on compatible axles.

✔ SAE J1204 Certified

Meets SAE J1204 standards for trailer wheel strength and dimensional requirements.

🚛 Common Applications
