1G /47re 48re Transmission Crossmember
1G /47re 48re Transmission Crossmember
Transmission Crossmember made to mount a 47Re or 48re transmission in your 1G 72-93 frame. It allows the transmission to be a direct bolt in. It replaces the original upper wing braces that waste space. This not only helps install the transmission, but helps with exhaust and driveshaft routing.
If you have a 4X4 1st gen Dodge crossmember, putting a 47/48RE and 2G/3G transfer case into your 1st gen Dodge, you need the top part to mount a 47 or 48RE.
If you have a 2WD 1st gen crossmember, putting a 47/48RE into your 1st gen Dodge, you need both pieces.
If you have no crossmember at all, putting a 47/48RE into your 1st gen Dodge, you need both pieces to make a complete crossmember.
If you are putting a B series Cummins and 47/48RE into a OBS, Dentside, Bumpside, Sweptline, Squarebody, Divco, Crosley, Model T, King Midget, Cessna, Bass Tracker, whatever. You need both pieces. The width and height of the part is for a 1st gen Dodge frame, but there is some capability of making it fit narrower frames.
If using an original 4x4 Cummins frame, it will use oem mounting holes. If converting a 2wd or updating an older 4wd, some frame drilling required.
We also offer the lower crossmember as an option. It is simply a replacement for the original 4x4 lower. This will work for a 2wd, just less ground clearance than original.
It includes a mount that isolates and bolts in a 47re transmission behind a Cummins. It includes 3 spacers to adjust tail shaft output height.
It allows installation and driveshaft clearance for a right or left side drop transfer case. 205, 241, 271 ect.
It features a maximum pass through area for straight exhaust. So both a large diameter tube is able to fit through, and either no dogleg for a driver side transfer case or a single offset for the passenger side transfer case rather than the double offset required to miss both the t-case and the original wing plate.
6” or 7” frames.
(The stock lower crossmember will have an inch tall spacer built in if it is from a 7” frame.)
