Performance upgrade complete assembly Complete Assembly Already assembled with the correct spring, top mount and insulators required for quick replacement. Monotube Design High pressure monotube design separates the gas and oil for fade free operation and instant response. This design works best on sports cars and on trucks and SUVs with higher roll center. Tow Ready Towing, hauling heavy loads and plowing require additional damping and control capabilities. KYB Monotube shocks are a great upgrade choice if you are using your truck or SUV. For Larger Tires and Wheels Larger, aftermarket wheels can add up to 25 pounds of additional weight to each corner. Original Equipment shocks and struts are intended for original tires and wheels, not larger, heavier ones. Truck Plus assemblies include additional damping over OE design and work well with larger, heavier tires and wheels. Increases Steering Response Steering response is a critical part of vehicle safety. Worn and economy shocks can allow fluid to travel through the shock valves too quickly, this reduces overall steering response. KYB’s shock valves are designed to help restore steering response to what the vehicle manufacturer intended. Adds Handling and Control With a faster response and additional damping over OE twin-tube designs, KYB monotube shocks are a great way to give your vehicle additional handling and control capabilities. Increases Stability With a faster response and additional damping, KYB monotube shocks provide more stability (especially vehicles with a higher center of gravity) when compared to traditional twin-tube shocks.The KYB Truck-Plus Performance Monotube AssemblyAdditional Control and easy to install the KYB Truck-Plus is an ideal solution for owners of modern ½ ton trucks who are looking to increase their truck’s handling and control capabilities. The Truck-Plus has all of the same research and testing as our Strut-Plus but includes a high pressure monotube strut. Monotube designs have two separate working chambers; an air-free hydraulic area for complete fluid control and a second high-pressure nitrogen gas area with a floating piston that automatically adjusts to add instant performance on demand.The KYB Product Team chooses the most appropriate base unit for each Truck-Plus application; either our popular Gas-a-Just monotube or our Heavy Duty MonoMax. For specific details by application, please check our catalog. All KYB Truck-Plus units are assembled in the USA.The KYB Truck-Plus is built specifically for trucks that work, go off-road, have larger tires and wheels, or haul heavy loads.The best shock won’t work well in assembly without great springs. KYB uses high carbon steel coil springs that are heat treated, stress relieved, cycle tested, and salt spray tested.
