Kit 4x4project 2.65 Prerunner Sprinter 906 and 907 3.8-4.5T

Camper vans and commercial vehicles among 3.8 and 4.5 tons They face unique dynamic challenges. The 4x4project 2.65 Prerunner Sprinter 906 and 907 3.8-4.5T Kit is not just an add-on; it's a complete upgrade designed from the ground up to replace the stock suspension and provide a definitive solution.

Suitable for Mercedes Sprinter W907 / VS30 4×4 (2018-on) y 906 / NCV3 4×4 (2006-2018)This kit brings racing technology to heavier chassis to ensure safety, comfort and performance on any terrain.

Competition Monotube Technology

We are the first to implement a real monotube system on both axles of a van.

• 60mm pistons: Housed in 2.65″ bodies, they offer a damping capacity far superior to the original.

• Chassis Reinforcements: The kit includes specific structural reinforcements that allow for a standard installation bolt-onproviding the necessary rigidity to support the extra weight of the vehicle.

Self-adjusting Digressive Valve

Thanks to its technology double pistonThe shock absorbers adapt instantly:

• Slow driving: It maintains a soft and comfortable filtration, ideal for long distances.

• Critical maneuvers: It automatically gains firmness to control swaying in curves or in crosswinds, providing the necessary resistance to avoid suspension bottoming out.

Exclusive Rear Coilover Option

The rear shock absorber allows the installation of a coilover support spring.

• Height adjustment: Its wide preload range allows it to compensate for the weight of heavy campers, full tanks or professional equipment, while maintaining the vehicle's geometry always perfect.

CCV Valves (Cavitation Control)

This fixed piston acts as a hydraulic accelerometer in the separate bottle:

• Resistance to Fainting: Multiplies thermal resistance by up to 60 %preventing the suspension from "softening" after hours on the track.

• Impact Protection: Avoid harsh suspension stops on rough terrain or after sudden changes in gradient.

FK Ball Joints and High Strength Stems

To manage the tonnage of these versions, we have oversized each support point:

• FK ball joints: Top quality, capable of withstanding up to 39,000 lbs radial load (150% longer lifespan). Includes belt of PTFE for quiet operation.

• 22 and 28 mm stems: With harshness 61-63 Rockwelldesigned to withstand extreme lateral forces without bending.
