Willys Jeep changing the bowl gear on a Warn overdrive! One of the coolest features of the Dana 18 transfercase is the ability to easily bolt on an overdrive. An overdrive splits your gears giving you more top end speed and greater control of your engine rpm. There are several brands of overdrives for Willys Jeeps but I am using a Warn unit. The same Warn that makes the legendary 8274 winches also made overdrives back in the day. I have to change out the bowl gear to match my Teraflex 3.15:1 Low Gears I installed in the previous video. This is an excellent, and easy bolt on upgrade for any cj2a, cj3a, CJ3B, or cj5!
