The output for the front drive shaft is on the right side and the rear output is in line with the input. This enables 2-wheel High to be direct-drive, which is quieter. Otherwise the Dana 20 offers the same drive modes as the Dana 18. Its low range has a ratio of 2.03:1. The Dana 20 is generally compatible with the "big hole" Dana 18.
When in "4-Low" mode the front and rear axles are locked together and power is sent to all four-wheels through the power transfer unit although no low range gear reduction occurs. Active Drive low relies on shorter axle gear ratios while holding first gear in the ZF9HP transmission to achieve a crawl ratio of 20:1; similar in effect to Freedom ...
The line was offered in four ratings, M-300, M-375 (also known as M-400 between 1969–1973), [1] M-500, and M-600 depending on the application. The M600 was offered with the Rockwell F-130-NX rear axle, with a 4.88:1 gear ratio. By 1979, Chrysler Corporation no longer sold incomplete chassis and ended production of the M series.
The Dana S110 is a full floating, drop-out axle. Dana S110 axles are a step up in overall strength compared to the Dana 80. Ford started using this axle in 2005 model F-450 and F-550 trucks. Replacing the Dana 80 in some class 4 trucks, and the Dana S 135 in the rest of the trucks. Dodge started using the Dana S110 in their 2008 model 4500 and ...
It had a 126-inch (3,200 mm) up to a 147" wheelbase chassis and featured the 230 cubic-inch flathead inline-six engine, a 4-speed manual transmission, a two-speed 1.96-1 ratio low range transfer case for part time 4-wheel drive with a power take off (PTO) which would send power front or rear for operating auxiliary equipment, and 9.00/16-8 ply ...
The transfer case may contain one or more sets of low range gears for off-road use. Low range gears are engaged with a shifter or electronic switch. In many transfer cases, this shifter is the same as the one that selects 2WD or 4WD operation. Low range gears allow the vehicle to drive at much slower speeds while still operating within the ...
Dana 44 Front axles were known for utilizing locking hubs or a center axle disconnect system. However, a permanently locked-in Dana 44 is not uncommon. The Dana 44 has seen use in 1/4-, 1/2-, 3/4-, and 1-ton rated trucks. The Dana 44 was manufactured in kingpin and ball joint variations, as well as closed and open knuckle variations.
The designation of wide versus close ratio affected the lowest gear ratio; [7] for example, the four-speed Muncie transmissions offered in General Motors performance vehicles included the M20 "wide ratio" transmission, which had a first gear ratio of 2.52 or 2.56:1, while the M21 and M22 "close ratio" transmissions had a first gear ratio of 2. ...
