3811995 3007573 3014453 3043911 3811994 AR-10012 Diesel Engine Connecting Rod For K19 KTA19 QSK19

Connecting rod (also called a con-rod) is a critical link between the piston and the crankshaft. Its primary function is to transmit the massive combustion force from the piston to the crankshaft, converting the reciprocating linear motion of the piston into the rotational motion of the crankshaft to deliver engine power. This connecting rod 3811995 3007573 3014453 3043911 3811994 AR-10012 is engineered for maximum durability and precise fitment in K19 KTA19 QSK19 engines. Manufactured to meet or exceed OEM standards, it ensures optimal engine performance and a long service life under heavy-duty conditions.

Whether for full engine rebuilds or quick replacements, DDP Engine provides you with the most reliable parts at unbeatable wholesale prices.

Parameter Details
Product Name: Connecting rod
Part Number: 3811995 3007573 3014453 3043911 3811994 AR-10012

Condition: Brand New / High-Quality OEM / Aftermarket
Warranty: 6 Months / 1 Year
Engine Model: K19 KTA19 QSK19 engines

Application:
K19: Mechanical fuel pump (PT system), non-electronic control, turbocharged intercooler (some models), widely used in 2000s–2010s heavy trucks, construction machinery (such as bulldozers, mining trucks), stationary generator sets, and marine auxiliary power;

KTA19: Based on the K19, add "T" (Turbocharging) and "A" (Aftercooler), still mechanically controlled, with power ranging from approximately 450–890 horsepower; widely used in mining dump trucks, large construction machinery (rotary drilling rigs, cold recycling machines), rail vehicles, high-power generator sets, and marine main propulsion. It is an enhanced version of the K19, does not use electronic fuel injection, and is not a replacement for the QSK19. QSK19: "QS" represents the Q-series (Quick Response) + K19 platform. It adopts high-pressure common rail electronic fuel injection (electronic control) and meets non-road Tier 3/Stage IIIA and above emission standards. It is used in modern high-power demand scenarios: 700–1210 horsepower ultra-heavy-duty tractors, large mining trucks, port machinery, large bulldozers (such as the SD52), stationary/mobile power stations, and marine power. It is currently the mainstay electronically controlled high-horsepower engine still in production.
