When putting together your differential you will want a top quality setup kit to ensure long life. Our new Ninja Setup Kits feature the same high quality seals and OEM Japanese bearings, but because this is our kit we are able to offer the same components at a reduced price! Includes our Heavy Duty Solid Pinion Spacer, pinion nut, and gear pattern paint.

Our Ninja Master Setup Kit uses the same high quality parts as a Yukon kit, but costs much less!

Don't settle on anything less. Make sure you run OEM KOYO and/or Timken Toyota bearings in your rig!

Note: V6 and High Pinion differentials are available and are an easy conversion. Converting to a 1986-1995 Turbo/V6 differential will provide larger bearings and a stronger 3rd member housing. But like the 4cyl 3rd member, it is limited by the standard rotation of the ring and pinion. Converting to a 1991-1997 FJ80 Land Cruiser front High Pinion 3rd member will provide larger bearings, a stronger housing and a reverse cut ring and pinion gear set. The high pinion provides increased front flange clearance, reduced front drive shaft angle, and it's gear set is substantially stronger in the forward direction. Please follow these links for pricing and info: Turbo/V6 & High Pinion.

Installation
Instructions

This is the World's First Gear Drive T/Case Adapter Kit for 4.0-liter 1GR-FE equipped Tacoma, 4Runner, and FJ Cruiser trucks with A750F automatic transmissions!

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 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 Tacoma, FJ Cruiser, and 4Runner 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 2005+ 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.
