Differential Stretch Bolt


  • This is the bolt that holds the output drive flange to the internal pinion of the differential.
  • Porsche part number 901-332-275-11.
  • Cost about $12.
  • I replaced the original stretch bolt with a new one. It is designed to stretch when tightened. I was skeptical of the 80 foot-lb value mentioned by the factory manual. Ismail Nuri sent me a note that his manual says 33-36 foot-lbs just like the bolts on the half shafts. Those values are much more reasonable.
