SOLID FLAT TAPPET<br />
HI-TECH SOLIDS<br />
These designs represent an excellent mix of horsepower, torque, rpm and durability. They work with .842” or<br />
larger diameter tappet, producing very good results. These have been used successfully in everything from NASCAR<br />
Nextel Cup and endurance applications to drag racing and hobby stocks.<br />

TIGHT LASH SOLIDS<br />
The designs for the tight lash solid .842” diameter lifters feature shorter seat timing and more area than similar<br />
designs. Good in restricted or open rules circle track racing. The larger designs perform very well in drag racing.<br />

HIGH RPM SERIES II SOLIDS<br />
High RPM Series II Solids are more aggressive than the original High RPM and Hi-Tech Solid profiles. They are<br />
designed for use in applications that need the area of an XTQ style lobe but are required to operate at higher engine<br />
speeds than that fast of a ramp will allow. HTL Lifters are highly recommended with these profiles. Note: <strong>Cam</strong>s<br />
using these lobes should have provisions for increased oiling. Please consult with our tech rep.<br />
