CheeMuii Trailer Hub Caps 4-Pack Replace Stemco 343-4195 — Aluminium with Sealed Oil Windows

CheeMuii 4-pack aluminum trailer hub caps with sealed oil windows replace Stemco 343-4195 style hubcaps for easy visual oil checks and durable axle protection.

These replacement hub caps from CheeMuii are a direct-fit aftermarket kit designed to match common Stemco and other OEM part numbers used on heavy trailers and axles. Each kit includes four die-cast aluminum hub caps, matching gaskets, and rubber seals engineered for tight sealing and simple installation (mounting bolts not included). The clear oil window gives a quick visual of hub oil level and condition so you can spot low or contaminated lubricant without removing the cap.

How do these hub caps make routine checks faster?

The built-in high-strength transparent oil window lets drivers and technicians inspect oil level and clarity at a glance. Instead of disassembling the hub or removing the cap, you can quickly confirm lubrication status during pre-trip inspections or servicing stops.

• Visible oil window made from impact-resistant plastic for clear inspection
• Sealed gasket and coated side plug to reduce leakage risk during checks
• Fits common bolt patterns for quick swap-in replacement

Will these hub caps physically replace Stemco 343-4195 and similar parts?

Yes — the CheeMuii caps are precision-machined to match the dimensional footprint and bolt hole pattern of Stemco 343-4195 and many equivalent references. Check the supplied measurements against your wheel hub before ordering to ensure compatibility.

• Bolt hole spacing: 6-3/4" on center to match common flange patterns
• Flange outer 7-1/4", flange inner 4-3/8", height 2-11/16" for accurate fit
• Inside depth 1-9/16" to accommodate typical axle end clearances

How do these hub caps resist leaks and wear?

The caps are die-cast from aluminum alloy with a polished surface treatment for corrosion resistance and strength. Sealing is increased with a gasket around the oil window and a side pipe plug coated with leak-proof glue to minimize oil escape under vibration and temperature changes.

• Aluminum alloy body provides corrosion resistance and low weight
• Oil window gasket and coated plug reduce seepage under road conditions
• Precision machining ensures even sealing surface against the flange

What comes in the kit and what else will I need?

The CheeMuii kit supplies four hub caps, four gaskets, and four rubber seals so you can service all four wheel ends on an axle set. Mounting bolts are not included, so reuse existing bolts if they are serviceable or acquire proper OEM-grade bolts during installation.

• Included: 4 aluminum hub caps, 4 gaskets, 4 rubber seals
• Not included: mounting bolts — verify bolt condition before reuse
• Compatibility: replaces Stemco 343-4195, 3434095, 3404195 and similar references

Who is this for: CheeMuii hub caps are ideal for fleet managers, owner-operators, and maintenance technicians who need a durable, visible way to monitor trailer hub oil without disassembly. Choose this kit if you require parts that match common Stemco dimensions, prefer aluminum construction for corrosion resistance, and value a transparent oil window for faster inspections during routine maintenance and pre-trip checks.
