Transmission-to-Transfer Case Adapters

Transfer Case Conversion
GM SM465 to Toyota 4cyl

We manufacture many upgrade parts for the 4-cylinder Toyota gear drive transfer case. Our heavy duty parts transform this 4-cylinder unit into a true beast. Among the many firsts Marlin accomplished was fitting this unit behind the more powerful and heavier 6-cylinder drive trains. Marlin made this possible way back in 1996 and since then 1988+ Pickup's, 4Runner's, T100's, Tacoma's, FJ Cruiser's, Tundra's and even rigs with non-Toyota 8-cylinder power plants have been able to run our reliable Rock Crawling products in their rigs! The rest is history.

Today we manufacture transmission-to-transfer case adapters for over a dozen 6-cylinder and 8-cylinder applications. Using our heavy duty upgrade parts, we have proven the strength and reliability of the Toyota 4-cylinder transfer case behind the following engines...

• Chevy small blocks
• Chevy 4.3-liter V6
• Ford 302 V8
• Jeep 258 & 4-liter I6
• Dodge 318 & 360 V8
• Buick 231 V6
• Toyota 4.7-liter V8
• Toyota 3.0, 3.4, & 4.0-liter V6
• Toyota F/2F/3F I6
• Toyota 5M & 7M I6

Our adapter plates provide the entire world of the RF1A gear drive Toyota 4-cylinder transfer case for your rig. Many of our Jeep applications with short wheelbases run our single 4.70:1 low range transfer case setups, while other applications such as Ford Bronco's and Chevy Blazer's choose to use our 5.2:1 or 10.7:1 dual transfer case setups. Our Toyota customers with engine conversions in 1979-1995 Toyota pickup's, and those with 6 or 8-cylinder 1995+ Toyota T100's, Tacoma's, 4Runner's, Tundra's & FJ-Cruiser's are finally able to do some serious C-R-A-W-L-I-N-G!!

Our current online adapters are mainly for Toyota Pickup, T100, Tacoma, 4Runner, Tundra, and FJ Cruiser applications. Please give us a call if you are looking for a specific adapter not shown here below.
