Toyota Dual Transfer Case Adapter - 21 Spline

Adapter to add a second low range box between your original transmission and transfer case for an extra low range gear. The stock low range ratio for Toyota gear driven cases is 2.28 to 1; with the addition of this kit you will have both 2.28 to 1 and 5.19 to 1 low range options. For even more gear reduction a 4.7 to 1 gear set can be added to one or both range boxes for extreme rock crawling low range. This kit requires a donor Toyota gear driven transfer case for the range box.
