*How to calculate which model is appropriate for your application:
  1. Make sure the vehicle is on flat, level ground.
  2. Measure the distance from the bottom of the frame rail (at driver's seat) to the ground.
  3. Measure the distance from the crank centerline to the ground.
  4. Use the formula below to determine the appropriate model.
Formula:  If the distance from the frame rail to ground is more than 3-1/2", subtract 3-1/2" from your measurement.
 

Example:

    
 

Frame rail to ground:

 5-1/2"  
 

Subtract Baseline:

 3-1/2"  

 

Difference =

 2"  
Next, subtract the difference from the crank centerline measurement to determine your adjusted crank center height.
  Example:    
  Crank centerline to the ground:

13.5"

  
 

Subtract:

2"

  
 

Adjusted crank center height = 

11.5"
