    Lowering shackles

    Anyone put lowering shackles on a nnbs? Do you have pics? Looking at Ground Force #91208 (2" rear). Can't make up mind to lower rear or raise front.

    DO NOT put shackles on! Rise the front by cranking the torsion bars up a little.

    the Bully Dog did wake it up a little. Everyone says to get Nelson Tune. I think I will try that next time. It cost the same.

    Shut your trap homie, maybe he wants a fast 4wd setup like Im going for

    Ill tell you this speedy, are you wanting to be fast or be lifted, cause its an extreme Pain in the rear and lots of $$ to be lifted and be fast. I was lifted and am going back to stock and lowering my 4wd an inch 1/2 in the front (with the HD Purple Keys) and 4" in the rear (2" block going out and 2" shackles). If you do want to lift it somewhat and put some offroad tires on it and still have performance I highly recommend only doing like 33s and the leveling kit for the NNBS.

    Even with shackles you can use your 4wd. You could even find some stock 2wd U bolts for the rear and take out the 2" Block as well. If you like the stance in the rear though and want to level it Id do the Rough Country Leveling kit. Its cheap too.
