With Camburg's rear shackles you can easily lift the rear of your Tundra with Camburg's 1.5 lift shackles. Not only are they longer than stock to give you the lift you're looking without stiffening the ride, but are built considerably stronger too. The stock shackles are just stamped out of them metal and bolted together. Camburg's shackles are laser cut from thick 3/8? steel and have a welded in gusset bridging the side plates together to eliminate flex. They powdercoat them wrinkle black and supply new metric bolts and hardware to bolt right into the factory mounts. These measure 6? bolt to bolt center in length, the stock shackles measure 4?. When using these with the stock leaf springs you may need to grind the serrated teeth on the leaf spring pivot sleeves so it slips into the shackle.
