67-inch WMS Driver Drop Fabricated Front Axle Housing

67" WMS Driver Drop Fabricated Front Axle Housing

Known for their strength, lightweight, and simplicity, Toyota axles are the perfect fit for many custom off-road projects.  Factory Toyota axle housings are available in a narrow range of widths which may not fit your crawler well.  Trail-Gear Fabricated Axle Housings allow you to use Toyota axles in nearly any width from the narrowest of moon buggies to full-size trucks. 

Trail-Gear’s 67” WMS Driver Drop Fabricated Front Axle housings are available for Toyota 8”, 8" E-locker, or 8.4" differentials and feature all of the same specifications as our Rock Assault 9 axles.  67” WMS Driver Drop Fabricated Front Axle housings are made to produce a 67” WMS using Toyota knuckle components. Both inner shafts are also included. This housing pairs perfectly with our 2005-2015 Toyota Tacoma Rear Axle Housing.

The knuckle balls included are brand new, so no need to source 30-year-old knuckle balls. Our knuckle balls are forged from 1035 steel, making them much stronger than stock and eliminating closed or bent knuckle balls.

We started with a 1/4" thick formed shell for the center section made out of ASTM A36 steel. This is a high-strength, low-alloy, structural steel plate with a minimum yield strength of 36,000 psi! All of this is attached to an equally strong 1/2" thick faceplate for anchoring the 1/4” wall 3.5” OD DOM axle tubes. The axle tubes are secured by the industry's first 3-point attachment system, giving the tubes superior support and engagement into the center section. We also face the center section to ensure your differential mounts flush against the axle housing to prevent leaks.

  • We recommend the addition of our Axle Housing Inspection Hole Kit (see 'Related products' below) to allow for easy fluid level and ring gear visibility. Just select "With Inspection Hole Kit Installed" in the 'Option' menu above. The kit is also available in a DIY installation version (requires drilling through the differential housing and welding on a threaded bung).
  • For Tie Rods, we recommend using our 51-1/4” Tie Rod (Part Number TGI-308983), sold separately.
