Feuling Parts Camplate PSI Testers

Feuling Parts camplate PSI testers are a must for any Harley-Davidson® Twin Cam engine builder. Bench-test each camplate before installation, cycle the pressure relief valve—testing the operation and ensuring that the valve moves freely, and seats and seals each time. Any leakage at the relief valve will reduce oil pressure. These camplate support tools let you know what PSI the relief valve opens; the spring tension can be adjusted to achieve the desired pop off PSI. Testers include: * Air regulator * 0-100 psi pressure gauge * Gaskets and needed hardware * Tool fits all Twin Cam engine camplates

COMP Cams XD-A Pushrods

COMP Cams's XD-A pushrods offer a game-changing method for accurately setting lash or pre-load while using non-adjustable-style rockers. These patent-pending pushrods incorporate a top section that slides 2 in. inside a wider bottom section, with one or two shims captured in-between. Proven to 9,000-plus rpm in solid roller LS applications, the system provides a 90 percent increase in bending stiffness for enhanced valvetrain stability. It also allows for lightening of a rocker arm system by 30-plus grams on the backside by removing the adjuster and required support area for threads and seating. The use of lighter rockers with XD-A adjustable pushrods allow higher rpm to be achieved by creating a much more dynamically stable valvetrain system. COMP Cam XD-A pushrods are designed especially for engines with low-mass rocker arms and a light valvetrain with drop-in fitment in LS engines. They can be adjusted over a range of .172 in. in .004 in. increments with shims. Choose the pushrods with the adjustment range needed for your setup.
