BSB Black 25 SERIES Monotube Bulb Shock Base Valve
The 25 Series Shock is a great piece and is way under priced for what you will receive in this shock. A lot of work went into getting it right and a lot of work goes into making it right every day and this was true for the base valve design as well. We spent endless hours studying base valve designs and come up with the conclusion, they were not made for racing. Most base valve designs are fashioned after a stock OEM shock base valve. We didn’t take the easy way and copy something that barely works. Karl our engineer friend, and that is Karl with a K helped us with some testing and flow designs to make sure that our base valve flowed oil correctly, and from that testing we came up with what is an excellent piece. This base valve because of its ability to flow oil allows us to run it about all of the time if not all of the time, this is the general problem with other brands of base valve shocks is that they don’t perform that well in all conditions. We have seen an increase in overall performance and grip in our customer’s cars using their current shock valving when they add our base valve ensuring us that the base valve design is working. In fact it works so well that we have discovered an issue with the low gas stuff that is on the market today and a way to fix it that is going to change the way we do things in the future.
