O-Ring Dust Cap Wide 5

The O-Ring Dust Cap Wide 5 from Strange Engineering is a precision-engineered protective component specifically designed for Wide 5 lug pattern axle systems. This dust cap is essential for protecting wheel hubs from contaminants, moisture, and road debris that can compromise bearing integrity and brake performance over time. It serves as a critical barrier, preventing corrosion and extending the lifespan of your components.

Manufactured with a durable O-ring seal, the O-Ring Dust Cap Wide 5 features precision-molded geometry that ensures a secure fit on Wide 5 axle housings without binding or rattling. The O-ring construction creates a dynamic seal that accommodates minor thermal expansion and contraction during temperature cycling, making it ideal for vehicles that see both street and track use. Measuring 2.75 inches in diameter and weighing only 0.01 lbs, the cap design minimizes unsprung mass while delivering maximum sealing effectiveness.

Technicians and builders working with Strange Engineering axle assemblies or any Wide 5 equipped drivetrain will benefit from having a quality replacement cap on hand. Installation is straightforward—simply snap the cap onto the axle housing hub until the O-ring seats fully. This ensures optimal protection against dust, grease loss, and water ingress that could otherwise degrade wheel bearings and CV joints.
