Suspension Lift Kit, EFS X-Treme HD +40 mm, Nissan Navara 2021 - Present

EFS X-TREME SUSPENSION KIT This kit integrates the main EFS suspension components, selected based on the required load and lift. It is a fully customizable base configuration that can be expanded with optional accessories to adapt to specific needs. It should be noted that this configuration is designed for constant load conditions. Weight variations will directly influence the final vehicle height. Furthermore, the indicated load and lift figures are indicative and depend on the particular conditions of each vehicle, so slight variations may occur. The kit has been configured based on the EFS X-TREME shock absorber range. EFS X-TREME SHOCK ABSORBERS: COMPETITION ENGINEERING FOR SEVERE USE The EFS X-Treme series represents EFS's premium segment, originally developed for the critical demands of 4WD competition and high-impact events like the "Outback Challenge." After more than a decade of evolution and testing in Australia's harshest environments, this range has been refined to offer a suspension solution that exceeds the capabilities of conventional systems, guaranteeing unsurpassed durability under extreme fatigue conditions. ADVANCED TECHNOLOGY AND CONSTRUCTION Unlike standard shock absorbers, the X-Treme model utilizes a high-bore purely hydraulic twin-tube design, optimized to manage high unsprung masses. Its architecture is designed to mitigate structural stress in high-impact frequency terrain, such as corrugated tracks and high technical difficulty off-road routes. MAIN FEATURES OF EFS X-TREME 45mm internal piston. 20mm extra-reinforced rod. High-strength 2mm thick outer tube. Fully hydraulic twin-tube design (no gas). Special high-temperature fluid.
