Why Hub-Centric Load Bearing Changes Everything for Dually Wheels

Most dually wheel failures come from stud fatigue. The fix isn't bigger studs — it's moving the load off the fasteners entirely. Here's how hub-centric load bearing works and why it matters.

Conical Seat vs Flat Seat: Why Gotham Forged Uses Both

Conical seat bolts center under load. Flat seat M22 bolts allow twist without fighting the fastener. Gotham Forged uses both — conical on the hub side, flat on the wheel side. Here's why.

The 10-Lug Semi Bolt Pattern: More Contact, More Strength, More Confidence

OEM dually wheels use 8 lugs. Semi bolt patterns use 10. More fastener points means better load distribution, less stress per stud, and a larger hub face for improved rotating assembly durability.

How a Wider Stance Improves Towing Stability on Dually Trucks

A wider track width improves lateral stability under towing loads. Here's the engineering behind how precision-fitted dually wheels with controlled offset create a more stable platform for heavy hauling.

Forged vs Cast Dually Wheels: What Oilfield Trucks Actually Need

Cast wheels are cheaper. Forged wheels survive. If your dually runs lease roads, hauls frac equipment, and works through Alberta winters, here's why the material choice matters more than the price tag.
