Hi all
as the subject title suggests is there such a thing as a LSD the fits a FJ 40 diff. I think its and early type as its got drum brake. Or what LSD will fit this diff ? Has anyone got an adaptor bell housing for a 4speed (early Hf 55 ) to SB ford or chev ?
thanks

A crusier lsd will fit but it'll need to be a full floater housing

you can get a 2 spider lsd to fit a semi floater housing .hard to find but know where one is

sorry to thread jack here

but if i weld the rear diff in my truck how much abuse wil it take before something gives??

im planning on welding it up and buying another open unit just incase

any thoughts??

is your diff a semi or full floater

do you have a torque arm of rear diff

and how much lead do ya have in ya right foot



My ol 40 had a very tight LSD in the rear and no torque arm, it was good enough to be able to drift on the road

never had any problems until it was sold and something went bang as soon as the new owner took possession

is your diff a semi or full floater

thanks but how do you tell the difference without stripping the diff

mine is a semi float diff ans no torque arm
im pretty heavy footed but would probably back off slightly with not having to go hard to get thru things but yeah its all a learning game i guess
