NEW: Updated Red Anodized "MC3X" Design!! Stronger plate design with improved seal adapter for better sealing performance!

Originally designed and created in 1997, this is the World's first Gear Drive T/Case Adapter Kit for any Toyota 6cyl truck in history! This plate will convert your 3.0-liter 3VZ-E equipped Hilux Pickup, 4Runner, & T100 trucks with R150F 5-speed or A340F 4-speed automatic transmission to allow a 1979-95 gear drive t/case to be installed, exposing your truck to the entire world of Rock Crawling!

Using our high quality USA-Made USA-Billet Aluminum, this adapter kit allows you to bolt a Toyota RF1A Gear Drive Transfer case behind your 5-speed manual or 4-speed automatic transmission. This opens the door for you to use our strong Total-Spline™ 2.28:1 TacoBox™ or Total-Spline™ 4.70:1 TacoBox Supreme™ Dual Case Products in your truck. This takes you to a Crawl Ratio of 79:1 with stock diff gears or as low as 210:1 with 5.29:1 diff gears. In the Automatic world this translates to a Crawl Ratio of two to four times slower than the typical Marlin Crawler equipped 5-speed setup.

This is seriously no joke! If you really want to Crawl, then go with the inventor and originator of Toyota 3.0-liter 6cyl, or as our very own Chris aka FloRunner calls it, "3-point-FLOW" Rock Crawling, Marlin Crawler!

We have designed our kit for use with a 23-spline gear drive transfer case input, such as our Total-Spline™ input for the strongest setup on the market, period.

Top-shift style transfer case or Crawl Box required. Includes our MarGasket, our Heavy Duty EcoSeal™ transmission output seal, and high quality OEM JIS Japanese mounting hardware.

Note: It is possible to use this kit in an automatic 1988-95 3.0-liter Hilux Pickup/4Runner by swapping out your stock auto for a T100 automatic! Call for more details!
