Clevite Bearing Guard 1 Gallon Bearing Guard - 2800B4

The Clevite Bearing Guard 1 Gallon (Part # 2800B4) is a professional-grade bearing assembly lubricant from one of the most trusted names in engine bearing technology. Clevite has built its reputation over decades as the go-to brand for high-performance engine bearings and engine components used in American performance and commercial vehicles. Whether you're a seasoned engine builder breaking in a freshly machined block or a professional shop stocking up for the season, this gallon-size container of Bearing Guard is formulated to protect critical bearing surfaces during the assembly process and initial startup — the moments when wear risk is highest.

Key Features & Benefits

• Professional Gallon Size: The 1-gallon format (2800B4) is ideal for engine builders, machine shops, and high-volume rebuilders who need a reliable supply on hand — no running out mid-build.
• Clevite Bearing-Specific Formula: Bearing Guard is purpose-built for bearing and engine assembly lubrication — not a general-purpose oil substitute — so your new bearings receive the right protection at the most critical moment of a build.
• Protects During Assembly & Initial Startup: Applied directly to bearing surfaces before installation, Bearing Guard helps prevent metal-to-metal contact during the vulnerable seconds before oil pressure fully builds at first startup.
• Trusted Clevite / MAHLE Heritage: Clevite is an American brand with one of the strongest traditions in high-performance engine bearings, as well as engine parts for American commercial vehicles — meaning this lubricant is engineered by the same team that designs the bearings themselves.
• Regularly Stocked Product: Unlike many specialty engine assembly products, the 2800B4 is a regularly stocked item — available when you need it without special-order lead times.
