Full-Flow Lube Oil Filter LF3972 for Cummins ISB 6.7 and Ram Heavy-Duty Trucks
The Oil Filter LF3972 is a premium spin-on lubrication element designed for high-performance diesel engines, including the legendary Cummins ISB 6.7L and ISV 5.0L power plants. Engineered for heavy-duty commercial and vocational use, the LF3972 features high-efficiency filtration media that captures microscopic soot and metallic wear particles. By maintaining optimal oil pressure and cleanliness, this filter ensures isochronous engine operation and prevents premature bearing wear, even under the extreme thermal stresses of stop-and-go school bus routes or long-haul trucking.
