Trail-Creeper™4.70 T-Case Reduction Gear Kit

For rock crawling, lower transfer case gears give you the control you need to keep your truck on track. Trail-Gear offers an affordable 4.70:1 gear kit for your gear driven Toyota transfer case. Trail-Creeper T-Case gears are available in 21 and 23 spline configurations. Kits include replacement gears, gaskets and seals. Disassembly and modification of transfer case is required for installation. Input gears are precision ground & micro-polished to guarantee the removal of all surface imperfections in the forging.

Choosing the right material for our gears was our top priority. Gears that perform well under load and street driving require a high quality steel alloy material. We chose Japanese alloy SCM415 for its great strength and wear resistance. SCM415 outperforms the 8620 material in yield and ultimate tensile strength resulting in a gear that is less prone to chipping or cracking. SCM415 also retains its strength under high-temperature use. High carbon materials such as SCM420 or 8620 are not the best choice in our experience and opinion as they do not carburize as well and can become brittle.

Trail-Creeper gears fit Toyota 4WD Pickup's and 4Runners from 1979-1995 with gear drive style transfer cases. Gear sets reduce the stock low range from 2.28 to 4.70, nearly twice the the reduction of the stock gears. High range is not affected and remains 1 to 1.

V6 applications require the transfer case be replaced with a 4Cyl gear drive unit and V6 Adapter plate. Speedo cable, floorboard, drive shaft, and crossmember changes may also be required.
