The German company MTU manufactures the engine components and the GD 883 engine is manufactured
under licensed production by General Dynamics Land Systems in the USA. The engine is transferred to Israel for installation and integration with the automatic transmission and with the engine computer control system. The tank has automatic five-gear transmission rather than four gears as in the Merkava 3. The transmission system is manufactured by Renk. The single position rotary shock absorbers are installed externally.
