If you have built anything that has serious horsepower you know the weak link can be the stock Ford 9" carrier. The pinion area tends to be weak and if you throw enough power at it, it will break. That won't happen with this brand new housing. 

This new cast iron housing is built to take street/strip abuse without the fear of breaking. Case has forged caps and extra beef where its needed. Most stock differentials use the 3.062" outer diameter bearings # TLM603049 w/ 1.781" inner diameter. You should also add a new heavy duty cast iron pinion support while youre at it. 

  • Forged Steel Caps
  • 5/8" HD Cap Bolts grade 8
  • Heavy Duty Housing - 36 lbs.
  • Good for 1100+ horsepower
