MCS 53-84 Hydraulic unit made in Japan

OEM reproduction premium quality hydraulic unit. Made in Japan high precision product. Replacement for OEM 17920-53A. Note: The early style hydraulic tappets sets can be purchased as a set (hydraulic unit + tappet body with roller) or as individual parts. When purchasing individual parts correct tolerance cannot be guaranteed which can influence hydraulic function. Dealers with a larger stock can mix and match hydraulic units and tappet bodies to compose a set that offers excellent bleed-down times. For all others it is advised to go for a complete hydraulic unit and tappet body assembly from the same manufacturer as S&S or JIMS offer. These are machined with the correct tolerance relative to each other to work correctly right out of the box.
