Jibs Posted August 12, 2004 Share Posted August 12, 2004 I was looking at the post in the marketplace about the dual range in an 81 Brat. Is the gear ratio different than in other Brats? I got the impression that the dual range from that year brat (81) seemed to be really good. Any help would be appreciated. Quote Link to comment Share on other sites More sharing options...
GLCraig Posted August 12, 2004 Share Posted August 12, 2004 It probably has the same ratios as the rest of the 81/82 DR 4 speeds. Which have a taller 3rd and 4th then the 83+ DR 4speeds Quote Link to comment Share on other sites More sharing options...

ezapar Posted August 12, 2004 Share Posted August 12, 2004 81-82 dual ranges have the same gearing. The change came in 83. The fourth gear is longer 83+, I'm not too sure about any difference in 3rd. I've had several of both to compare. If it had a taller 4th gear then that would make it an overdrive transmission. Quote Link to comment Share on other sites More sharing options...
GeneralDisorder Posted August 12, 2004 Share Posted August 12, 2004 Yeah - the 3rd and 4th gears in the 81/82 are shorter. Good for a lifted rig, since the big tires don't like high gearing. Otherwise they just get crappy gas mileage on a stock setup. GD Quote Link to comment Share on other sites More sharing options...

mcbrat Posted August 12, 2004 Share Posted August 12, 2004 here is the list of gear ratios from the 82 FSM... http://www.ultimatesubaru.org/80s/specs/mechanical/gears.html Quote Link to comment Share on other sites More sharing options...
GeneralDisorder Posted August 12, 2004 Share Posted August 12, 2004 Actually - it's *over* 1:1, so 4th IS overdrive. The ratio of the 81/82 4th gear is like .942, where the ratio of the 83+ 4th is like .885..... 3rd gear is something like 1.344, and 1.266 respectively. Look at his chart ^ it's better than my memory :-p What I don't get about that chart, is it seems like 82 4WD wagon's didn't exist..... which they did.... for sure. Heh.
