Composite Steer Hub Cap 2 PCS with Gaskets & Bolts - Durable Seal

In this review of the Composite Steer Hub Cap set, the bottom line is simple: this 2 PCS replacement kit is for trailer owners and fleet technicians who need a lightweight, corrosion-resistant hub cap that makes oil checks easy. The reviewer found it most useful when replacing worn plastic or OEM steel covers because the composite construction and clear oil window speed up routine inspections. The kit includes gaskets and 12 flange bolts and is sized for common steer applications, so the single biggest reason to buy is the combination of durability and serviceability.

Key Features

• Complete replacement kit: Ships with 2 hub caps, gaskets and 12 flange bolts so you can swap both sides without hunting additional parts.
• Composite, oil-filled body: The high-impact composite resists salt, chemicals, corrosion and UV to prolong service life in harsh road environments.
• Transparent oil window: The clear viewing window lets mechanics check oil level quickly during routine stops to help prevent bearing damage.
• Reliable sealing: A vented one-way center plug valve and molded pressure ridge improve sealing and help keep contaminants out of the hub.
• Easy mounting: Six bolt holes on a 4 1/2' bolt circle with 5/16' hole size make it compatible with many steer hubs for straightforward installation.

Who It's For

This hub cap set is aimed at owners of trailers, trucks and fleets who need a cost-effective replacement for SKF 1612/1711, Stemco 343-4024 and like-for-like OEM Ford, Freightliner, Kenworth, Peterbilt and Volvo steer hub caps. It is a practical choice for DIY mechanics who value corrosion resistance and a visible oil window during inspections.

Those who should look elsewhere include operators who require a specific metal hub cap design for heavy-duty impact scenarios or who need an exact OEM branded cast steel assembly; this composite design prioritizes weight and corrosion resistance over raw mass.

Pros & Cons
