Product Design Philosophy

Cast iron crankshaft with 82mm main journals and 66mm rod journals. Precision-machined and dynamically balanced to withstand high combustion loads, ensuring smooth power delivery and durability in 4HF1/4HG1 engines.

How it works

Receives reciprocating force from pistons through connecting rods, converting it into rotational torque. Drives the flywheel, timing gears, and accessory pulleys to power the vehicle and engine systems.

Problems the product can solve

Fixes engine vibration, knocking, oil leaks, and power loss caused by worn or bent crankshafts. Restores smooth rotation and reliable power transmission for NPR trucks.
