Sway Bar Rate Calculator
Front: Front:
Motion Ratio: 0.75   Sway bar rate (lb/in): 460.7159
Virtual torque arm (A): 5 in Sway bar wheel rate (lb/in): 259.1527
Length of center (B): 32 in
Physical torque arm (C): 7 in
Diameter in millimeters: 20 mm
     
A - Length of end perpendicular to B (torque arm - inches)
Rear: Rear: B - Length of center section (inches)
Motion Ratio: 0.875   Sway bar rate (lb/in): 202.0873 C - Length of end (inches)
Virtual torque arm (A): 7 in Sway bar wheel rate (lb/in): 154.7231 D - Diameter bar (inches)
Length of center (B): 42 in
Physical torque arm (C): 7 in I changed the diameter input to millimeters since that is how sway bars are usually sold.  This calculation does not take into account flex allowed from sway bar bushings, which can be very significant when using soft rubber bushings.
Diameter in millimeters: 20 mm
