For 1966-1971 CJs, utility wagons and pickups, this kit reduces the 2.43:1 stock low-range ratio to 3.15:1. Older CJs (1953-1965) require a transfer case housing from a Jeep 1966-1979 Dana #18 or #20 large case.



NOTE:

Shift Rod: It is necessary to shorten the shift rod (#29) approximately ½" off the inside end so that it will clear the intermediate gear.

Case Requirements: Because the Low18 conversion kit fits only the larger Model #18 cases, CJs older than 1965 will require a case from one of the following vehicles in order to use it:

1966-71 CJ

1963-79 Wagoneer or pickup #20

1972-79 CJ #20



The Dana #20 case will interchange with the #18 components and still allow output shaft locations to remain offset.
