46-64 Station Wagon

Replacement Saturn Overdrive
Fits 41-71 Jeep & Willys

New Replacement Overdrive

Comes complete with shifter and everything you need for install. This all-range overdrive is a great addition to any of the early model Jeeps from 1940 to 1971. The addition of this 25% overdrive unit offers you the needed gearing the early Jeeps were lacking.

The Saturn overdrive is a fully synchronized unit that can be shifted-on-the-fly. When installing the unit, only minor modifications are required to the floorboard for the shifter. The Saturn is built to handle up to 300 ft./lbs. of torque, well within the range of a stock V8.

The Saturn is the original unit designed and developed by Warn Industries. The units were offered with the 6 and 10 spline internal assembly and the 26 or 29 tooth output gear.

The Saturn overdrive installs directly on the backside of the transfer case through the inspection cover. No cutting or modification of the drivetrain is required. No relays and electrical connections required.

Just as other reviews state. Have 43 GPW W/t-90. Can hit the highways now and do a constant 50 to 55 with no straign on engine. Sound like I am doing 35 -40. We can now take longer trips.

Had one in a '66 cj5 w/225 buick V6. Without the OD engaged the top speed was between 45-50. Just to see what she would do engaged, I had her up to 80 once. Handles 65mph very nicely. Instead of being pushed off the highway I was keeping right up with everyone else. Soon as I can afford another OD I'm going to put it on my 54 Willys truck.

This is an amazing little unit. So easy to install it makes you wonder if there's actually more to it than there really is. Gives an additional 25% speed increase and gets you up to highway speeds without the fear of destroying your hard work in rebuilding your engine. This unit is without a doubt the single most important upgrade that can be done to the old jeeps
