Competition Engineering Rear Ends

  • Competition Engineering has designed and built a rear end housing far stronger and more accurately produced than any other housing on the market.
  • The .125" thick sheet metal shell is designed with over lapping joints that provides two weld seams. This greatly improves the strength as compared to butt-welded housing shells.
  • Housing comes in standard 26.00" flange to flange width.
  • Built to withstand Advanced E.T. applications, internal bulkheads stiffen the shell to the face plates to prevent any movement and add strength around the housing mounting brackets.
  • The 3/8" thick face plate is CNC machined to ensure proper axle alignment to the center section. The face plate is machined after the housing is welded, so the alignment will not be compromised after welding the housing together.
  • All models come with a –6 AN drain plug, 1/8" NPT fitting for a vent, and an aluminum o-ring filler cap.
  • All housings have machined symmetrical housing ends
  • Carrier Stud Kit No. C9006 available separately
