Moroso Race Oil Filters
To maximize filter performance, Moroso race oil filters have a filtration rating of 27 microns. This results in a maximum pressure drop of only 2.5 psi, which results in more flow, less oil bypass, and maximum filtration performance, which is so important in severe racing conditions. Made with roll-formed threads for a precise, tight fit, and with an anti-drainback valve to keep oil in the filter after engine shutdown, they are perfect for any race application.

Moroso timing pointers feature up to four degrees of adjustment for the best fit. They are manufactured from billet aluminum and have a black anodized finish applied for maximum corrosion resistance. The pointers have a unique smaller shape to hug the harmonic balancer for better, more accurate readings. Moroso timing pointers also include Allen head, countersunk stainless steel mounting hardware for installation.

Moroso Cam Stop Buttons
Professional engine builders are familiar with camshaft walk. Excessive camshaft end play can produce erratic spark timing and the movement of the timing chain/gear can destroy the timing cover. Moroso has solved this problem with a wear resistant cam stop button that mounts in an aluminum holder, which bolts to the cam gear by way of a retaining plate. These button assemblies do not allow the cam to walk forward, stabilizing ignition timing and preventing costly engine damage.

Moroso Oil Restrictor Kits
When roller rocker arms are installed, along with a mechanical lifter cam, the amount of oil flow required to the valvetrain is greatly reduced. Installing Moroso oil restrictor kits limits this unnecessary oil flow. These kits reduce the power-robbing windage created from the excess oil draining past the rotating assembly and keeps the oil flowing where it is needed most, the rod and main bearings.
