What length floating shafts

[rallyrob]

What length fully floating shafts do I need for a 54" Atlas?
Are 765mm too long?
Cheers

approx 735mm

Ok thanks Mick, I thought 765mm might be a tiny bit too long.

i have a 54.75 inch ff atlas for sale at the moment and the shafts measure 740mm.full length 770mm shafts should give you 57inch overall so for 54inch overall i actually think 740mm minus 3/8 of an inch 9.2mm approx,so 740-9.2=730.8mm.Remember to assemble your hubs on to stub axles then measure the depth just to be sure,measure twice cut once .

So if I had a pair of shafts that were 675 long I just cut down the diff spline end, obviously?
Or would that not leave enough spline lenght inside the diff?

[mick32]

675?seems a bit short my experiance is most shafts come 770mm and will go down to 720mm with enough spline for side gears.i think quaife does shafts that would go to 680 maybe 690 i think that would be used on a baby atlas fully floater.

Apologies... I ment 765mm... So I should get those to go down to about 730 ish leaving enough on them for the side gears...

yes but as i said earlier measure at least twice check again then cut.
