The kit includes four oil-filled composite hub caps with gaskets, vents, a clear oil window and 24 flange bolts, making it a practical swap for several OEM numbers. The single biggest reason to consider it is the combination of a molded pressure flange, an embedded aluminum ring for even mounting load, and the transparent oil window that simplifies routine maintenance.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eComplete kit:\u003c\/strong\u003e Four hub caps plus gaskets and 24 flange bolts let a user service both sides of a steer axle set without sourcing extra parts.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorrosion resistance:\u003c\/strong\u003e The high-impact composite body resists salt, chemicals and UV, which helps maintain seal integrity in harsh road conditions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVisible oil level:\u003c\/strong\u003e The clear oil window removes the need to disassemble the hub to check lubrication, making routine checks faster and safer.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eImproved sealing:\u003c\/strong\u003e A molded pressure ridge on the flange and a one-way vent plug reduce the chance of contamination and help prolong bearing life.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEven mounting load:\u003c\/strong\u003e An embedded aluminum ring distributes bolt torque evenly across the flange to help prevent leaks and warping.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThis kit is a good fit for trailer owners, fleet mechanics and DIY technicians who need a direct replacement for common steer hub cap part numbers like SKF 1612, 1711 and Stemco 343-4024, and for those who prefer a lightweight composite cap over heavier metal options.
