SOLID FLAT TAPPET<br />
NRX SOLIDS<br />
The NRX Solids are designed for use in Nextel Cup engines with 55mm or larger journals. They are designed with<br />
higher lobe lifts than the standard journal families to allow either less ratio or higher lift. Use in applications with<br />
less than 55mm journals will result in a small nose radius and premature wear.<br />

CHRYSLER SPECIAL SOLIDS<br />
These lobes are for use only in Chrysler engines with .904” tappet diameter. The “Specials” are to be used in 426<br />
cubic inch or larger engines. Developed for the Top Fuel drag racing program, these designs offer excellent torque<br />
and horsepower.<br />

MP SOLIDS<br />
The MP Series uses a design similar to the TL Series, except these have more area due to being designed with<br />
more velocity for a .904” minimum tappet diameter. They are very good in Late Model Stock applications where<br />
rules allow the larger tappet diameter. Note: <strong>Cam</strong>s using these lobes should have provisions for increased oiling.<br />
