1400hp vs 700hp axles

[Tom Tucker]

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.

20% more expensive for 100% more capability seems like a no brainer

[Tom Tucker]

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

Out of curiosity, what's different in putting 700hp shafts in vs 1400?

[Tom Tucker]

700s bolt in like factory replacements. 1400s require new hub assembly and new wheel bearings

[Tom Tucker]

Ended up ordering the 1400hp suckers. Comes with new hubs and bearings

Gonna rip a skid when they're fitted?

[Tom Tucker]

On the balance of probability, yes.

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?

[Tom Tucker]

Ok, Repco do sell a Kelpro version. Part number 98258. $30 per seal.

 

Just changed them out. Bit of a bastard to get the old ones out.
