TREMEC Driveline Finder App iconThe TREMEC Toolbox App for iOS and Android smartphones will help you simplify driveline setup, predict the effects of changing gear ratios and tire size, and calculate vehicle speed and RPM variables.

This Toolbox is great for planning your rig, allowing you to see what kind of performance to expect from different combinations!

The TREMEC Toolbox contains:

1.    Driveline Angle Finder.

Take the guesswork out of your chassis setup with this handy 3-step tool!  By using your smartphone as a measuring device, the app will calculate each u-joint angle and provide an overall driveline operating angle with a Pass/Fail response.

This unique tool will help you avoid vibration problems associated with incorrect driveshaft and u-joint working angles.

The three-step graphical interface provides measurements essential for proper driveline setup, along with tips and instructions that make it possible to check angles like a pro! Designed for RWD vehicles equipped with a one-piece driveshaft.
