Description
Hydraulic tappets are critical to maintaining precise valve timing and protecting your roller lifters from premature wear—especially in high-mileage or heavily modified Big Twin engines. JIMS’ billet bearing steel construction and hand-fitted hydraulic units eliminate slack in the valvetrain, ensuring consistent performance whether you’re running cast iron or aluminum tappet blocks. If you want reliability without guesswork, this is the upgrade serious riders choose.
