CLUTCHjr includes all the variables required to accurately determine the plate load characteristics of your clutch. Inputs include the manufacturer and size of the clutch, the number and style of the arms, the ring height and arm depth, and the static and counter-weight being used. From these input data, it calculates the plate load (static and centrifugal components) that your clutch will provide over the entire engine RPM range.

CLUTCHjr provides a side-by-side graphical comparison of your current clutch setup and a new one you might be considering. It quickly calculates the differences in plate load at any RPM for these two clutch setups. CLUTCHjr is absolutely the most affordable and easy to use drag racing clutch management software available! On-screen help is included to make CLUTCHjr simple to use. A complete user manual is also included and technical support is always available to all registered users.
