1400hp vs 700hp axles


Recommended Posts

Hello gents,

 

Who's done the 1400hp shafts themselves? I've heard it's a horrible job. 

 

I'm tossing up which way to go. The 1400hp shafts, plus wheel bearings come out 20% more expensive.

 

I'm told that I'm very unlikely to break a 700hp shaft with less than 1000hp, especially with no drag racing, stalling up etc. Although manual is worse for shock loading.

Yeah, the only thing I'm worried about is if its a nasty job that I can't do myself, the extra cost of installation may push it to 40% more expensive. Which is potentially 40% more than required in the first place

So I've pulled the rear cradle out and I'm going to town on replacing all bushes while I've got the knuckles out for these new axles.

 

But I have a question about the diff axle seals. Is there an alternative to the Ford ones, which seem to cost $60 each? It seems excessive for just a piece of rubber. Is there a repco equivalent that anyone has used?

I found the same on one I replaced that was leaking it was an absolute pita to change. Nekminit it still leaks

I noticed inside the rim was scratched and assumed I’d done it given how much of a beach it was to take out but since it was leaking beforehand I think whoever had changed them before me had already scratched it up

700hp ones are actually 1000hp rated and plenty for 99.9% of the falcons on the road.

 

The only reason they were downgraded to 700hp is due to the release of the 1400hp ones.

that's good to know ive been running the 700hp rated shafts for the last 3 years daily driven & plenty of roll racing events
But I haven broken 1 shaft back when the car had 324rwkw on the baby turbo
