When installing a dual case Crawl Box into your truck, your transfer case will be moved back the distance of the Crawl Box, which is 6-1/2". Because your speedometer cable attaches to the tail housing of the transfer case, it must be lengthened in order for it to reach. On 1979-83 first gen pickups with their short L-series transmission, it is possible to reroute and reconnect the cable, however the cable will experience high tension and stress from tight bends and a lack of mobility, and in our experience will soon fail.

Our 8" speedometer cable extension provides the necessary distance to reattach the cable properly without any binds or tight corners. This is a must for all 1984 and newer applications, and strongly recommended for 1979-83 applications.

Fits the standard 22mm X 1.50 Toyota mechanical spending unit and speedometer cables of many 4WD as well as 2WD applications. We are able to build custom length extensions cable as well, please call for more details!
