Is your Mercedes-Benz Actros losing power, burning excessive oil, or struggling with fuel efficiency? These symptoms often signal that your OM471 engine needs an overhaul. The Mercedes-Benz OM471, a 12.8-liter inline-six diesel engine, powers heavy-duty trucks like the Actros, Antos, and Arocs, delivering up to 530 horsepower and 2,600 Nm of torque. Renowned for its X-Pulse injection system and Euro 6 compliance, the OM471 is a workhorse in the trucking industry. However, maintaining its performance requires high-quality components, especially during an engine rebuild.
Enter the quad package—a set of four critical parts (piston, piston rings, cylinder liner, and piston pin) designed to restore your OM471 engine to peak condition. At Volgen Power, we specialize in OEM-compatible quad-package parts that combine durability, performance, and affordability. Whether you’re a fleet manager minimizing downtime or a technician tackling an overhaul, this guide will walk you through the OM471’s needs, the role of quad package parts, and why Volgen Power is your trusted partner. Let’s dive into how our parts can keep your trucks rolling strong.

Understanding the OM471 Engine
The Mercedes-Benz OM471 engine is a cornerstone of heavy-duty trucking, introduced in 2011 for the Actros and later adopted in Antos and Arocs models. This 12.8-liter inline-six diesel engine delivers power outputs from 421 to 530 horsepower and torque up to 2,600 Nm, making it ideal for long-haul and construction applications. According to Daimler Truck, the third-generation OM471 (launched in 2022) achieves up to 3% better fuel efficiency and enhanced low-end torque, thanks to upgrades like optimized turbocharging and refined X-Pulse injection.
The OM471’s advanced features include:
- X-Pulse Common Rail System: Developed by Bosch, this system delivers injection pressures up to 2,700 bar for precise fuel delivery and reduced emissions.
- Asymmetric Turbocharging: A single or dual-stage turbocharger ensures high torque at low RPMs, improving drivability.
- Euro 6 Compliance: The engine uses selective catalytic reduction (SCR) and a diesel particulate filter (DPF) to meet strict emissions standards, as outlined by DieselNet.
These technologies demand components that can withstand extreme pressures and temperatures. A typical OM471 rebuild, including the quad package, can extend engine life by up to 1.2 million miles (1.9 million kilometers), per Heavy Duty Trucking. Choosing high-quality parts is critical to maintaining these performance metrics and avoiding costly downtime, which FleetOwner estimates can cost fleets $400-$700 per day per truck.
What Are Quad Package Parts?
The quad package, also known as the “four-piece kit,” is the backbone of any OM471 engine rebuild. It includes four essential components that work together to restore the engine’s combustion chamber and power output:
Piston: The piston compresses the air-fuel mixture and transfers combustion energy to the crankshaft. Volgen Power’s OM471 pistons are forged from high-strength steel with manganese phosphate coatings and graphite-coated skirts, reducing friction by up to 15% compared to standard pistons, per IPD Parts. These pistons are designed to handle the OM471’s 2,700-bar injection pressure and maintain performance under high thermal loads.
Piston Rings: These rings seal the combustion chamber, control oil consumption, and transfer heat to the cylinder liner. Volgen Power’s piston rings use advanced alloys to ensure a tight seal, minimizing blow-by gases and supporting the OM471’s fuel efficiency. According to SAE International, high-quality piston rings can improve fuel economy by up to 2% in heavy-duty engines.
Cylinder Liner: The liner provides a durable, wear-resistant surface for the piston. Volgen Power offers both APR (Anti-Polishing Ring) and non-APR liners for the OM471. APR liners reduce carbon buildup by up to 30%, extending maintenance intervals, as noted in DieselNet. Each liner includes seals to prevent coolant leaks, critical for the OM471’s water-cooled design.
Piston Pin: This component connects the piston to the connecting rod, enduring torque loads up to 2,600 Nm. Volgen Power’s piston pins are made from hardened steel with precision machining, ensuring durability under the OM471’s high-torque demands.
These components are engineered to work seamlessly with the OM471’s advanced systems, such as the X-Pulse injection and asymmetric turbocharging. A complete quad package rebuild can restore up to 98% of the engine’s original performance, according to IPD Parts, making it a cost-effective solution for fleets and owner-operators.
Why Quality Matters for OM471 Rebuilds
The OM471 engine’s advanced engineering places unique demands on its components. The X-Pulse system, with injection pressures up to 2,700 bar, requires pistons and rings that can withstand extreme forces without deforming. Similarly, the asymmetric turbocharger generates high cylinder pressures, necessitating robust liners and pins. Using low-quality or incompatible parts can lead to catastrophic failures, such as piston seizures or liner cracks, which can cost upwards of $10,000 in repairs, per FleetOwner.
Poor-quality parts also compromise the OM471’s Euro 6 compliance, increasing emissions and risking regulatory fines. For example, a worn piston ring can increase particulate emissions by 20%, according to DieselNet. Additionally, substandard liners may fail to support OM471’s APR technology, leading to carbon buildup and reduced engine life.
Expert Tip: “When rebuilding an OM471 engine, always verify the part’s material specifications,” advises Dr. Emily Carter, a heavy-duty engine specialist at SAE International. “For the OM471, look for forged steel pistons with manganese phosphate coatings and APR-compatible liners to ensure longevity and compliance with Euro 6 standards.”
Volgen Power’s quad package parts are designed to meet these demands, adhering to ISO 9001:2015 standards. Our components undergo rigorous testing to ensure compatibility with the OM471’s high-pressure systems and thermal loads. By choosing high-quality parts, you can reduce maintenance frequency by up to 25% and extend engine life by 500,000 miles, per industry benchmarks from Heavy Duty Trucking.

Choosing and Installing Quad Package Parts
Selecting the right quad package parts for your OM471 engine requires attention to detail. Here’s how to make the right choice:
Verify Engine Model: Confirm your OM471 variant (e.g., OM471LA, Euro 6) and serial number to ensure part compatibility.
Choose APR or Non-APR Liners: APR liners are ideal for reducing carbon buildup, while non-APR liners may suit older models.
Bundle Complementary Parts: For a thorough overhaul, including head gaskets, main bearings, and oil filters to maximize performance and longevity.
Installation is a precision task. Follow the Mercedes-Benz service manual for torque specifications and alignment procedures. Use professional tools to ensure proper seating of the cylinder liner and piston. Inspect the X-Pulse injection system and turbocharger for wear, as these components can affect the quad package’s performance. Volgen Power provides detailed installation guides and 24/7 support to streamline the process.
A typical OM471 rebuild with a quad package takes 10-12 hours for a skilled technician, per TheTruckersReport. Post-rebuild, perform a break-in period of 1,000 miles to ensure optimal seating of the piston rings. Regular maintenance, such as oil changes every 30,000 miles, can further extend the life of your rebuilt engine.
