Determine axle manufacturer and spindle style - straight or tapered. If the axle was MTIS prepped at factory, use MTIS
Prepped Kit (less press plugs and stators).
Identify wheel size and determine axle count. Use the charts below to select the correct retrofit kit.
See Page 8 to select the appropriate style of hubcaps (hubcaps included in full ThermALERT™ kits) .
Determine hub material - Ductile Iron or Aluminum.
