FORD BRONCO TRANSMISSIONS
ATLAS TRANSFER CASE & ADAPTERS

NV3550 Transmission and Adapters
Ford Bronco NV3550 Transmission and Adapters

4 to 1 low first gear and .22% overdrive means excellent driveability both on and off road. This transmission is great as a daily driver and weekend wheeler. Its smaller overall size lends itself easily to swapping in without the need for relocating the transfer case or driveline changes. This transmission has a 300 lb.-ft Torque rating with a 7,200# GVWR (11,000# GCW). Required to do this swap is an adapter from the transmission to a stock bellhousing complete with clutch disk and an adapter to the transfer case with shifter bracket, cross member mounting kit, shifter knob and handle. At least a 1” body lift eases installation. J shift T-cases require use of twin stick.

#3671 NV 3550 Transmission for Early Bronco swap - Rebuilt - $1799.00
#3672 NV3550 to Dana 20 Transfercase and T-case shifter bracket, $478.00

Bronco Billet Shift Knob Billet Shifter Knobs
Brushed Billet aluminum shifter knob CNC’d with NV 3550 shift pattern. Threaded 3/8”-16 but will likely need to be easily drilled and tapped to fit most 3550 shifters. Includes jam nut.
#2161-3550 Billet NV 3550 Knob $35.00

Early Bronco Atlas II Transfer Case Atlas II Transfer Case
The Advance Adapter Atlas II Transfer Case is the Ultimate replacement case for Early Broncos. With a 3.8 or optional 4.3 to 1 low range it gives the benefits of lower gears for off road crawling and allows for higher gears in the axles to maintain freeway comfort and gas mileage. Of course, if this transfer case is combined with low axle gears it provides excellent slow speed traction and control. With its twin stick shifter, independent control of front and rear output is available. Equipped with shift on the fly capability. Unit comes fully assembled ready to be installed with CV style output yokes. Requires a 2" body lift. With this case, a set of lockers and our Ultimate Suspension, you can be crawlin' with the big dogs! Due to slight variations please call for pricing on this special order item.
#3440 Atlas Transfer Case, 4.3 Low Range, $2395.00
#3441 Atlas Transfer Case, 3.8 Low Range, $2395.00
