how do you do it as got diff stripped just now as fitting a 4.1:1 cwp into a 4x4 cossie rear diff

 

you need to send it to a company that does teh uprating process , i.e changing teh viscous fluid and pressure,

www.gearboxman.co.uk

i wouldnt recommend it at all, also i hope your fitting step offs for that 4.1 ratio in the gearbox ?
