hi all

i need som new labro bolts for the sierra 7" diff anyone know the best place to get them none of the local motor factors do them,

Thanks for your help all

Sean

I just used M8 hex socket head bolts from Namrick. Can't remember the length though.... Make sure you de-grease them well first and if possible give the threads in the lobro on the diff a clean with some thinners on a cotton bud...

[edited to remove my brain fade M5 instead of M8 mistake]

hi thanks for the reply,

my only concern with that is i am running 300bhp through the back wheels so not sure the tensile of that bolt will be enough ??????

but may be my only option if i cannot locate some

thanks again
sean

Well cap head bolts will be 12.9 which is pretty hard as nails. I very much doubt Ford make 'em any stronger. Infact is there a grade stronger than 12.9? Never seen it if so....

Hang on a min, they're no M5, talking borrocks. They're M8*50 capheads. Sorry...

Hex(socket) should be the same 12.9 hardness as the original (star?) anyway. Bear in mind that its not only the tensile strength but also the clamping action on the 2 faces that take the force

57p each from namrick btw (12.9 grade)

i shall give them a go then it can only break

thanks all but if anyone still knows where the originals can be got please post away

thanks again

ps do you have a link to them thanks

Ebay item 200376713015

£3.89 for 10....

Its not the bolt that takes the load, if torqued correctly all the driving force is by the friction between the 2 faces created by the bolts

12.9 cap head will be more than enough
