ULP Alu Progressive Shock System - Set (2)
When the piston is at the bottom of the shock, it moves softer and dampening becomes harder when the piston is going to the top. This means that the shock dampening is softer in the first part of movement and becomes harder when the car is moving more. The shock inserts must always be used with pistons without holes, must be used both front & rear, and only on asphalt. The same oil is used in these insert-equipped shocks as with standard shocks. The inserts are CNC-machined from premium Swiss 7075 T6 aluminum, and are black coated. The pistons are molded using special processes & composites to ensure roundness, while maintaining maximum stiffness and durability. The pistons are additionally precisely grinded.
