Kit 4x4project 2.65 Prerunner Sprinter 519 DRW
La Mercedes Sprinter 519 DRW It is the preferred base for the heaviest Overland preparations and demanding industrial applications. However, its large volume and high center of gravity require damping capable of absorbing massive inertia. Kit 4x4project 2.65 Prerunner Sprinter 519 DRW It transfers high-performance racing technology to the 519 chassis, offering unprecedented stability without sacrificing comfort.
Designed as a system Direct-FitIt is installed 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 its lateral roll and sensitivity to wind. Our intelligent system of double piston act according to need:
-
Cruise comfort: Gentle filtering 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 bottle, it is vital for heavy vehicles:
-
Anti-Fading: It multiplies resistance to thermal fade by up to 60 %preventing the suspension from "softening" after hours of work.
-
Impact Protection: It 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 piston rods of 22 mm:
-
Structural Shielding: 3mm induction tempered with high-density hard chrome finish.
-
Maximum Resistance: With a hardness of 61-63 RockwellThese 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 lifespan).
-
Marching Silence: band of PTFE (Teflon) standard features to ensure smooth and noise-free operation.
-
Tilting System: It 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, a 30% higherIt reduces back pressure and heat generation (Laws of Thermodynamics), maintaining stable and predictable damping even at full load.
