TNT billet aluminum offset leaf spring shackles. Designed specifically to fit 1967-1981 Camaro/Firebird and 1968-1974 Nova/Ventura, but will fit almost any leaf spring car. CNC precision machined from T6061 T6 billet aluminum with a black hard anodized coating. This coating is 100% necessary to prevent premature wear on the shackles, don't be fooled by others that sell these without being hard anodized. Moves the leaf spring inboard 1 3/4". Fits up to 335mm tire on Camaro/Firebird with mini-tub and up to 315mm tire on Nova/Ventura with mini-tub.
Note: You WILL need to use a fuel cell, or narrowed factory gas tank. You will also need to move the spring perches inboard a little on your axle housing.
