CheeMuii Trailer Hub Caps 4-Pack 343-4195 — Aluminum Replacement Caps with Oil Inspection Windows

This kit supplies four die-cast aluminum hub caps finished for corrosion resistance, each fitted with a clear oil inspection window and sealing components so you can monitor hub lubricant without disassembly. The caps are precision-machined to match common bolt patterns and flange dimensions used on many commercial trailer axles, making them a practical direct-replacement option for a range of OEM part numbers.

Will these hub caps fit my trailer axle?

They are manufactured to match the bolt circle and flange sizes listed for Stemco-style caps, but you should confirm your hub's measurements before buying. Key dimensions are provided so you can compare with your existing hub to ensure compatibility.

• Bolt hole spacing: 6-3/4" on center
• Flange outer diameter: 7-1/4"
• Flange inner diameter: 4-3/8"
• Overall height: 2-11/16"; inside depth: 1-9/16"

How do the inspection windows help me maintain my hubs?

Each cap includes a high-strength clear plastic oil window so you can visually check hub oil level and condition without removing the cap. This quick visual check helps you spot low oil or contamination earlier, enabling timely topping up or service.

• Transparent window shows oil level and color
• Window cover resists impact and wear
• Tight-sealing gasket prevents leakage around the window

What’s included in the CheeMuii 4-pack kit and are mounting bolts provided?

The kit contains four aluminum hub caps plus four gaskets and four rubber side seals, prepared for direct installation where bolt hardware is already present. Mounting bolts are not included, so you’ll need to reuse existing hub bolts or source the correct fasteners separately.

• 4 x die-cast aluminum hub caps
• 4 x gaskets for oil sealing
• 4 x rubber side pipe seals coated for leak resistance
• Mounting bolts not included — use existing or order separately

Which OEM parts do these replace?

CheeMuii designed this kit to be compatible with a variety of OEM part numbers, offering an economical alternative to branded caps. Verify that one of the listed replacements matches your current hub part to confirm interchangeability.

• Replaces Stemco 343-4195, 3434095, 3404195
• Interchangeable with Automann 180.CR1869 and National 343-195
• Compatible with Meritor A3262J1180 and similar flange designs

Who is this for: This 4-pack suits fleet owners, trailer repair shops, and DIY mechanics who need reliable, visible hub covers for routine inspection and maintenance. If your trailer hubs match the listed dimensions and you already have the correct mounting bolts, the CheeMuii kit provides a cost-effective replacement set with visual oil monitoring to simplify upkeep.
