3.9 diff conversion whats needed??

[the youth]

I have a 3.9 front and rear diff. but not going to use the front one I want to fit a step down in the transfer box but I'm not sure exactly what to get and where from?
presume its just the lower cog and a shorter chain?? but what spec?

I have a 3.9 rear diff and was going to fit step down in the box but as i have a shot peened and super finished front 3.9 i am just going to see what happens before i spend about £500 on the step off and new chain

Ken, I've been told the 3.9 front diff is weak not recomended at my power level

The 3.9 front diff won't last long atall, if you think the standard front diff is weak then the 3.9 is going to be even worse!

For what the fronts diffs cost to buy second hand I'd chuck it in and see what happens lol

£30 will see you another 1 if it strips it's teeth, then go 3:6 and drop gears

My escort on 3.9 gearing and 909 sport box only got 100 mph but it is so fast though the gears,and round the lanes its a monster

Problem is if it breaks that's my race weekend over!
Hence wanting a better solution,
I just want to know what and where to buy them!!

Either call G.E.A.R.S or BARA

Both will supply you with the drop gears and chain to suit the 3.9 set up

Expect to pay between £450 and £600
