Cylinder liner assembly 5878133931 for the 4HG1-TC engine in NPR models

Product Design Philosophy

Thin-wall dry liner design for 4HG1-TC engines. Made of wear-resistant iron alloy, precision-cast with grade-matched sizing (1X/3X) for reliable sealing and heat transfer under turbocharged conditions.

How it works

Dry liner is press-fitted into the cylinder block bore, forming the combustion chamber wall. It seals with piston rings, guides piston movement, and transfers combustion heat through the block to the cooling system.

Problems the product can solve

Fixes bore scoring, power loss, and oil burning from worn liners in 4HG1-TC engines. Restores cylinder sealing and extends engine life without replacing the entire cylinder block.
