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, 27 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.

Question By: Dave on Jun 28 2016 8:30 PM
Really you would never run the overdrive while you are in 4WD because you should never be going that fast while in 4x4.

Questions: I have a 56 Willys CJ5. The emergency/parking brake is between the drive shaft and the transfer case. Will that interfere with the overdrive unit?
Question By: Anonymous on Oct 25 2011 12:00 AM
No this will not interfer. It bolts to the access cover next to it on the back side of the transfercase. It is made specifically for this application.

Questions: Can the stock driveshaft be used or does it have to be modified or replaced?
Question By: Terrance on May 6 2011 12:00 AM
Your stock driveshaft is fine. It bolts to the back of the transfercase next to the driveshaft on the inspection cover. So it does not interfer or change anything on the stock driveshaft.

Questions: The description of the Saturn overdrive talks about different splines. Do you need to know which spline configuration you have and specify for ordering.
Question By: Anonymous on Apr 21 2011 12:00 AM
It is either 26 or 29. We can tell by your vehicle. Or you can count it be removing the cover plate on the back of your transfercase.
