Re: help find me an 3.45 diff

what sort of take off difference would this 3.45 make, compared to standard?? i would have thought a better option (maybe more expensive too) would be to go higher, to get a more noticable take off... although Im asking, because im not really sure

Re: help find me an 3.45 diff

the xr diffs are a better ratio in respect of punch out of the hole, but spin faster at speed. the 3.45 ratio has much better take off than the 3.08 ratio found in those vehicles other than the xr series..

Re: help find me an 3.45 diff

Here's a vid of my car doing 0-100 with a 3.45, used to have a 3.08 and it took 8.1sec 0-100, now it does it in 7.7 but this vid shows me uphill and with a full tank of gas.

Worth a look.

Made a little vid of my car

Re: help find me an 3.45 diff

I totally recomend gettin this done in an AU. I had a 3.23 non-lsd (standard base falcon) and I got a 3.45 LSD from an xr6 HP. It really improved take off and power through corners as well. I paid heaps for it as the entire rear axel and diff setup had to be repaired due to an accident. Dont ask me where to get one though. It was just luck that I found someone who had one in stock.

Re: help find me an 3.45 diff

It funny you guy say its hard. The diff in a Ford is a BTR/BW, these diffs have basically been runnig since the 70's. I got a 2nd hand 3.45 R&P including supply put in my charger for $250 dollars total! Every diff shop I have been too has 2nd Hand 3.23, 3.45, and 3.55 R&P's in stock. Also you can get a reco LSD fitted for $450 (new was $650). Why bother searching the scrap yards when they want $500+ for a questionable diff.

Dont forget to add bearings to that $350

LSD new $650
Bearings $350
and new gears depending what ratio is about $300-$650.
In my case total was $1525 +GST

So $500 for a questionable diff dose'nt sound to bad it just depends what your application is my car is about to get a blower so second hand parts dident seem like a good idea. Are you sure that all the diff centres are the same/interchangable i thought that there was different series even though they are the same basic design.
