TW-CrossTie XLP Billet Ford 9" / 10" Third Member Extreme Race System



A fundamentally different approach to the traditional third member assemblies. The TW-CrossTie X-LP system can dramatically improve gear life through measurable improvements in gear position control and is designed to utilize the Tubeworks Championship winning DUPLX triple bearing pinion cassette / support.

The Patent Pending TW-CrossTie X-LP is designed with a constrained rotating girdle system that virtually eliminates problematic case / bearing cap spreading.  In addition, it constrains the ring gear to the pinion side of the case.  The ring gear is now pulling on the thick, structural side of the case.  A traditional third member the ring gear pushes on the opposite side of the case, past where there is a massive cut out. This physically spreads the bearing caps under load and is well documented.  In more specific terms, the system results in 92% less bearing cap load and stops case deflection.

More Notable Features of the TW-CrossTie X-LP:

  • Machined from aerospace grade weldable, aluminum alloy billet, the TW CrossTie X-LP has a reduced case structure and 24 lbs of weight savings
  • Aluminum alloy actually helps increase girdle clamp-up force between 200 to 300 degrees F, opposite function of a traditional billet or cast aluminum case.
  • Fits 100% of every existing Ford 9” concept housing with minimal to no housing modification.
  • Internally reinforced smooth pyramid type design that resists debris build-up.
  • Accepts all current 9, 9.5, 10’s and the new True 10 gears coming in 2021.
  • Empty Case weighs in at 11.5 lbs
  • Complete 10” 4.11 Assembly weighs in at 66 lbs.
  • Optional 3.812 or 3.25 spanner conversion rings allow ALL aftermarket differential / locker units to be used. {Loss of rotating girdle function will result}
