mattj Posted September 5, 2016 Share Posted September 5, 2016 Hey guys, I have a 1981 B1600 with a 4.8 ratio diff in it and it needs to be changed, from what I understand you can fit Ford Courier, B2000 and B2600 heads into the housing but is there any particular year or model that I need to be looking for? What I want ideally is a 4.1 lsd head Cheers Matt Quote Link to comment Share on other sites More sharing options...
J-W-G Posted September 7, 2016 Share Posted September 7, 2016 Matt most common LSD is 3.7 or 3.9? Cant remember off the top of my head Find them in alot of b2000/b2200 and couriers (XLT/4WD)Youll need to notch the housing for it to fit though Quote Link to comment Share on other sites More sharing options...
mattj Posted September 7, 2016 Author Share Posted September 7, 2016 OK thanks, so is there a particular model that I need to look for or are they all the same and as long as it has come from a B2000/B2200 or a Courier XLT then it should be sweet?

mattj Posted September 7, 2016 Author Share Posted September 7, 2016 I think the housing has already between notched, so that's a bonus Quote Link to comment Share on other sites More sharing options...
johnny.race Posted September 9, 2016 Share Posted September 9, 2016 Is that head you are after ... is it 30 Spline or something else? Quote Link to comment Share on other sites More sharing options...
mattj Posted September 10, 2016 Author Share Posted September 10, 2016 Not sure, it is a standard b1600 one whatever that is, I will take it out this week and have a look Quote Link to comment Share on other sites More sharing options...
J-W-G Posted September 11, 2016 Share Posted September 11, 2016 Rue - will be a 30 spline if its b1600 Matt - The spec will probably matter as I think XLT was the only one it came standard but i could be wrong. Best to go pulling diffs mate Quote Link to comment Share on other sites More sharing options...
johnny.race Posted September 12, 2016 Share Posted September 12, 2016 Yep, ta. I got a few of those diffs. I checked today and a couple of them are 4.1:1 LSD's. The rest are 4.1:1 opens and there might be a 4.4:1 open in there too. Anyway $400 each for the LSD's and $200 each for the open ones. They will all be in excellent nic. When I pillage one of these trucks - I only pillage the good looking ones. Have not got any other parts for these trucks. Was going to offer these in narrowed form but they have a cunt hub end on them if you are in the 'narrowing ya bum business' Not collecting anymore of these diffs either. Will sell 1 x LSD plus 1 x Open for $475 for both. If you only want one - then prices as above. You need to organize uplift. will be on TM when i get around to it. Cheers. 1 Quote Link to comment Share on other sites More sharing options...
mattj Posted September 16, 2016 Author Share Posted September 16, 2016 Hey thanks for that, just a few days too late for me as I already bought one, I got a 3.5 ratio out of a 90's XLT Courier, the B1600 housing wasn't notched quite right but that was no biggie and I had to swap the driveshaft flanges over but other than that it went in ok. 1 Quote Link to comment Share on other sites More sharing options...
