    I just installed a rear add-a-leaf to my 71' k5 and was wondering what is the correct torque for the center bolt nut. I have tightened it to the point where im afraid if I go anymore i might strip out the nut. At this point I can barely move the overload leaf with some strength....is this good enough? Please reply -Thanks

    ShinnyH,
    I'm not exactly sure of the centerbolt torque spec, but generally when I install the centerbolts, I use c-clamps to pull the leaves together with the bolt or a screwdriver placed in the leaf holes to keep the holes lined up. Then once the leaves are pulled together , install the centerbolt and tighten the nut. The nut does not need to be super tight, since the axle u-bolts keep the spring sandwiched. Those u-bolts are torqued to 110 ft-lbs. Good luck, JT
