S&S CycleRotor Set, Oil Pump, Supply, Oil Cooled, 2017-up M8 Models

✓ Verified fit for your 2021 Street Glide 107

⚠ Fits with conditions: OIL COOLED variant -- fits base/non-CVO Touring and all Softail M8 (the standard air/oil-cooled architecture). Does NOT fit CVO Touring models, which use the Water/Twin-Cooled architecture instead. Same caveat pattern as this catalog's existing SS-C-007 cam chest kit (A1/A2 batch).
