Liner 8943916020 8943916021 8980140461 suitable for NPR75 NQR90 FSR90 FVR34 models fitted with 4HK1 6HK1 6HH1 engines

Product Design Philosophy

Dry-type liner with precision 115mm bore and 180mm length. Centrifugal casting ensures uniform metallurgy, with grade-matched sizing for reliable sealing and heat transfer in high-power Isuzu engines.

How it works

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

Problems the product can solve

Fixes cylinder bore scoring, power loss, and oil consumption caused by worn liners. Restores compression seal and extends engine life without costly full-block replacement in commercial trucks.
