Vehicle Fitment
- Fits Toyota 8.4″ rear differential housings using 30-spline axles (commonly T100, Tacoma, early Tundra).
- Many listings reference 1993-2015 Tacoma, 1993-1998 T100, 2000-2006 Tundra, 2001-2007 Sequoia, and similar platforms.
Why Choose This Dropout?
- Plug-In Convenience: Factory pre-shimmed & backlashed, no setup needed on install.
- Strength & Stability: Nodular iron case helps maintain precise gear contact under load.
- Traction On Demand: Grizzly Locker delivers torque to both wheels under load for improved performance off-road.
Install Notes & Considerations
- After installation, fill with correct gear lubricant and follow break-in procedures for new gears/locker.
- Torque housing bolts to spec and verify proper sealing of the differential cover.
- Because the locker locks both wheels under load, expect increased tire wear in tight, high-angle turns.
- Verify your housing, bearing dimensions, and axle setup match a 30-spline 8.4″ Toyota housing before purchasing.
