About this app
Take the guesswork out of chassis setup with the TREMEC Toolbox
The TREMEC Toolbox 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:
• 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. Designed for RWD vehicles equipped with a one-piece driveshaft.
• Vehicle Speed Calculator: Interactively determine your vehicle’s speed in any gear and any engine RPM for best performance. You can alter the axle gear ratio, the transmission gear ratio and tire size to see the impact in real-time. As an added bonus, the calculator doubles as a Gear Ratio Calculator.
• RPM Calculator: Determine what RPM your engine will run based on gear ratio, tire size, transmission and MPH. Try various combinations to come up with the best combination of gear ratio and tire size for your vehicle.
• Tire Size Calculator: Convert the funky P-Metric tire size (Example: 265/75R16) on the side of your tires to inches to simplify these drivetrain calculators!
