20 Series Base Valve Shock

The 20 Series base valve shock is a another outstanding piece in shock technology and is a winning machine, so much that we can’t even tell you who is running this shock. Primarily this shock is used for a Northern Sport Mod because of the rules, but can be run anywhere that allows it, but because of its ability to find the best part of the race track it is almost like taking candy from a kid. Unlike others our Base Valve went through great under takings and extreme testing to become a proven winning piece. It is unlike others that have been built. In fact that allows you to run it under track conditions that other base valves can’t handle. It likes the rough and performs extremely well in those conditions. During development of the 20 Series Base Valve Shock it won a National Championship on an IMCA Northern Sport Mod and an unbelievable number of races, which also included 16 straight wins on a USRA B mod. If you want additional feel from the race car this is the piece for you.

Shock Valving

Shocks can be valved in any configuration or in standard valving, also see Shock We Build to get a better understanding of the shocks we build.

Standard builds would be 4040 which is a 4 rebound and a 4 compression, see valving chart to see pressures at 10 inch per second.

Custom builds will be more like RF1-50 +130
