TL-R SOLID ROLLER SERIES .750" roller diameter
The TL-R Solid Roller Series is a tight lash roller profile. These lobes are designed with torque and reliability in mind. It is typical to find that less duration on these lobes can be used than with a wider lash profile. These profiles can be used as intake or exhaust lobes. Lash on this series profiles range from .012" to .016" depending on rocker arm ratio and use as an intake or exhaust lobe.

RX SOLID ROLLER SERIES .750" roller diameter
The RX Solid Roller Series profiles were originally designed for engines with 1.7:1 to 1.8:1 rocker arm ratios, but they have been successful in Small Block Chevy applications as well. RX profiles are used in alcohol oval track and drag racing applications and are very popular in Big Block Chevy applications such as DIRT Modified and IMSA Supermodified classes. These profiles are normally used on, but not limited to, intake lobes.

R-ULX SOLID ROLLER SERIES .750" roller diameter
The R-ULX Solid Roller Series profiles are, without a doubt, Reed's most popular cam series. They are very versatile profiles that are used as intake lobes as well as exhaust lobes. They are normally used as an exhaust lobe when using a SR, SRA, or RX intake lobe. These profiles were designed with versatility and reliability in mind, without compromising performance. The R-ULX profiles can be used with all popular rocker arm ratios and is categorized as a competition, high rpm, oval track and drag race cam profile.
