This is big! We have three brand-new 4.70:1 SM420-to-ToyBox kits!

These kits allow a 1979-1995 Gear Drive Toyota Transfer Case to be mounted behind a GM SM420 4-speed transmission, and feature our 4.70:1 Competition ToyBox Gear Set designed for use with a SM420.

These ToyBox kits have only our MC20 front adapter + 4.70:1 gear set; We do not have the MC21 or MC22 adapters to mate a 3- or 4-speed Land Cruiser t/case behind the ToyBox.

So what you can do with these parts is mount a 4.70:1 Crawl Box behind a SM420. From there, you can continue with the complete transfer case or run a standard Marlin Crawler Dual Case setup using additional adapters.

Specifically, this kit is popular with short wheel base vehicles using a center rear end as follows: Engine > SM420 > 4.70:1 Toyota Gear Drive T/Case > Center Rear End + Right-hand Front End.

A common use is in short wheelbase rigs. You can now have a 7.05:1 transmission + 4.70:1 single t/case. Combined with, for example, a 4.88:1 R&P, you'll have a Crawl Ratio of 162:1 in a single transfer case short wheelbase FJ40 Land Cruiser or CJ5 Jeep!
