Kit 4x4project 2.65 Prerunner Sprinter 519 DRW

The Mercedes Sprinter 519 DRW is the preferred base for the heaviest overland builds and demanding industrial applications. However, its large size and high center of gravity require suspension capable of handling massive inertia. The 4x4project 2.65 Prerunner Sprinter 519 DRW kit brings high-performance motorsport technology to the 519 chassis, offering unprecedented stability without compromising comfort.

Designed as a Direct-Fit system , it installs quickly and without modifications, radically transforming the active safety of your vehicle both on the road and on bumpy tracks.

Digressive Valve: Balance Control

The biggest challenge with a 519 DRW is lateral roll and wind sensitivity. Our intelligent twin-piston system acts as needed:

• Cruise comfort: A smooth filter for long days of driving.

• Maneuvers and curves: The shock absorber automatically gains firmness when it detects tilting, keeping the body level and providing a feeling of total control.

ACV Valves (Hydraulic Accelerometer)

Inherited from our 9200 competition series, the ACV valve located in the separate reservoir is vital for heavy vehicles:

• Anti-Fading: Multiplies resistance to thermal fade by up to 60% , preventing the suspension from "softening" after hours of work.

• Impact Protection: Acts as an internal hydraulic stop that prevents sharp impacts, protecting the chassis supports and the vehicle body.

High Hardness Stems (63 HRC)

The Sprinter 519 subjects the shock absorbers to extreme lateral forces. Therefore, we use 22 mm shafts.

• Structural Shielding: 3mm induction tempered with high-density hard chrome finish.

• Maximum Resistance: With a Rockwell hardness of 61-63 , these stems are virtually immune to bending and stone impacts.

FK Ball Joints and Load Components

We eliminate the imprecision of conventional rubber silentblocks through heavy-duty engineering solutions:

• Oversized FK Ball Joints: Capable of withstanding radial loads of up to 39,000 lbs (150% longer service life).

• Running Silence: Standard PTFE (Teflon) band to ensure smooth, noise-free operation.

• Tilting System: Allows the shock absorber to work in alignment at all times, reducing internal friction under heavy loads.

Thermal Management: Massive 2.65″ Diameter

A larger diameter means greater oil capacity and, above all, greater nitrogen capacity.

The technical benefit: The separate bottle, 30% larger , reduces back pressure and heat generation (Laws of Thermodynamics), keeping damping stable and predictable even at full load.
