Alko Extreme Duty shocks and struts are designed for hard working trucks and vans carrying loads. They offer improved vehicle stability when carrying loads and reduce body roll and nose dive during braking. Their durable design gives maximum control when off-road, hauling, and towing.

• Seamless Cylinder Tube - Low Friction, Durability, High Performance
• Vehicle Specific Damping Forces - Optimal Damping and Spring Oscillation Control
• Maximum Size 50mm -70mm Cylinder Tube Diameters - Increased hydraulic oil capacity compared to OE replacement shocks. Dissipates heat quickly resulting in lower operating temperatures and increased service life
• Galvanic Hardened 18mm or 20mm Chrome Plated Piston Rods - Increases fluid displacement resulting in quick reaction to road impacts. Chrome Plated finish RA 0.05 provides excellent, low-friction surface mating to the HNBR Oil & Gas Seal increasing service life
• Fuchs® Low Viscosity High Performance All-Weather Hydraulic Oil - Provides excellent thermo-stability and constant damping forces at high operating temperatures
• HNBR Oil & Gas Seals - Superior low friction, self-lubricating HNBR Oil & Gas Seals provide excellent sealing properties at high operating temperatures ranging up to 135°C/275°F compared to NBR seals used in most aftermarket brands with a high temperature tolerance of 120°C/248°F
• Rugged Polypropylene (PP) Dust Cover - Provides superior piston rod protection from road debris. Excellent heat resistance under high operating temperatures
• Piston - Sintered Piston with Low Friction PTFE Banded Seal. Extremely Durable delivering precise damping force values
• Piston & Foot Valve Mounting - Coil Spring Valve Mountings and Steel washers. Provides quick reaction to road impacts producing higher damping values in a shorter stroke
• Natural Rubber Bushings with 3mm hardened steel insert - Natural Rubber provides greater flexibility and durability than polyurethane bushings controlling harsh vibrations and high frequency noise. The 3mm hardened steel insert is the proper thickness for bolt torque specifications to secure against lateral movement
• Liquid Metallic Paint Finish - High quality electrostatic metallic paint finish for added protection against chipping caused by stone, gravel, and road debris
• Nitrogen Gas Charged - Controls Cavitation (Oil Foam) and delivers consistent performance under tough driving conditions.
