Dometic BayStar 1.4 Cubic Inch Front Mount Helm. Greatly reduced "chatter" noise that is typically generated by overrunning steering loads. Improved check valve durability with a more robust design (resulting in better trailering performance as well as longer service life). Eliminated flow noise when coming off hard-over position. Decreased clicking sound of the lock valve spool during steering reversal. Tighter, more responsive steering resulting in better "regrip" performance (also known as precession). Full compatibility with existing SeaStar hydraulic steering systems. 3/4" STD taper.
