A gas shock absorber has a pressure tube which defines a working chamber. A piston divides the working chamber into an upper working chamber and a lower working chamber. A series of extension passages extend through the piston and are opened and closed by an extension valve assembly. A first and a second series of compression passages extend through the piston and are opened and closed by a first and a second compression valve assembly, respectively. A rod guide assembly is located between the pressure tube and a piston rod. The rod guide assembly includes an oil chamber for sealing and lubricating the piston rod.

1. A damper comprising:a pressure tube forming a working chamber; a piston disposed within said working chamber, said piston dividing said working chamber into an upper working chamber and a lower working chamber, said piston including: a piston body; a first plurality of obstruction free compression passages extending entirely through said piston body; a second plurality of obstruction free compression passages extending entirely through said piston body; a plurality of extension passages extending through said piston body; a first compression check valve disposed adjacent said piston body, said first compression check valve closing said first compression passages, said first compression check valve being the only means for closing said first compression passages; and a second compression check valve disposed adjacent said piston body, said second compression check valve closing said second compression passages, said second compression check valve being the only means for closing said second compression passages.
