(1) A newly designed rotary retainer that does not restrict the movement of the spring in order to bring out 100% of the performance of the spring.
?Since the performance of the spring that was not used until now is released. you can feel further performance improvement by readjusting the spring rate and damping.

*Many damper ends can be used.
(ReveD. Yokomo. Tamiya. and other ball ends with joints within 6.3mm can be used.)
