Eco-Crawler - The easiest & strongest gear box for your Toyota 4x4.

Current Eco-Crawler Lead Time is 8-10 Weeks on all Variations

At Northwest Fabworks we set out to produce products our customers are as proud to own as we are to make them.  Since 2005 we have poured our passion for manufacturing into the 4x4 industry and continue to set the bar high through responsive support, unmatched quality, and manufacturing our products in house.

Initially working with the domestic transfer case market, we garnered a cult following with our Blackbox, EcoBox and Titan series product lines.  Proven to improve handling and control through selectable gear reduction, our development team set out to bring the same innovation to the much-needed Toyota market, and the Eco-Crawler was born. Existing dual Transfer case or Gearbox options for 1984 – Current VF Chain drive equipped Toyota 4x4’s are either poorly executed, or non-existent. Previous systems required sourcing old gear drive components, purchasing multiple adapters, and the end result was weak, unreliable and excessively long. 

How did we do it ?

Instead of utilizing sections of an older transfer case, the EcoCrawler kit provides a new billet aluminum housing that accepts stock VF transfer case planetaries. The housing is a direct fit to the stock transmission, and doesn’t require any shaft adapters or couplers.

How Does It Work ?

A chain drive transfer case is required to use as a "donor" for the EcoCrawler. The low range planetary unit is removed from the donor transfer case and inserted into the EcoCrawler housing. A custom NWF input shaft is installed into the vehicles transfer case. This produces an integrated connection between the EcoCrawler and the transfer case, removing the requirement for a splined coupler. Watch the video at the top of the page for a visual understanding of the process!

What is Required :

Donor VF Chain Drive Transfer Case for Planetary Gears. - See Fitment Guide at the top of the previous page for best choice.

*Torsen Type VF Transfer Case are NOT Suitable for donor gears.

*Stock "J" Shift Style Levers are required if not using NWF Trident Shifters (One Touch 2-4 Shift Lever is NOT Compatible with the Eco-Crawler)

IMPORTANT:

  • EcoCrawler does not support RF1A transmissions (Lid bolt pattern), but will support 23 spline top shift RF1A transfer cases (base bolt pattern).

  • Dana 300 Eco-Crawler does not fit Midnight Metalworks D300 transfer case.

  • Atlas transfer cases require modifications to the cable shifters for proper fitment and functionality. Direct linkage shifters for the Atlas DO NOT fit with the EcoCrawler. For details, please call customer support at +1-(250)-248-6024.

  • When mating an Eco-Crawler to a VF4 Transfer Case from the Tacoma 6 Speed Manual, the input retainer must be shortened. The Outside O-Ring Groove will be your cut line.
