More Information:
The Type RS uses a unique conical, progressive rate spring that can allow for the retention of boost pressure from 7 to 22 psi. If you are running over 22 psi then you will need the uprated spring, which is included in the kit. This unique spring design will also allow for unrestricted piston travel and flow volume regardless of the amount of pre-load adjustment added to the spring.
