    Hi all, been enjoying the forum for awhile now and am finally chiming in with a question.
    I have 77 FJ40 and a 88 FJ62. I am planning on taking the 40 off the road to do a restro on it and want to make my 62 a little off roadable. I have a lock rite in the 40 with 3:73 gears, I am wondering if I can put the lock rite into my FJ62 which has 4:10 gears? Also how much lift can i put on the 62 with out having to add shims to turn the diff?
    Thanks,

    Yep, same Lockright Part#1630. Gear ratio doesnt matter with the locker...

    I would assume any spring lift needs shims in the front to correct the front diff.

    you sure you have 3:70's in the 40?
    4:10's were stock that year
    Oh, and in theory a spring manufacturer will design the spring to require no shims. Messing with shackle length usually dictates whether or not you need shims. every 3/4" you add to a shackle changes the pinion one degree on a 44" spring ( FJ60 front, as an example )

    I've only pulled a Lockright once, but I found it more difficult to pull it than install it. Removing the springs without mangling or loosing them was the tricky part. You may want to have a spare set of springs on hand before yanking the Lockright.
