American Automotive solid cast iron lift blocks are stronger than aluminum and cast as a single, more stable construction than blocks with pressed pins. They are designed to increase rear load and towing capacity. American blocks absorb noise and vibrations, and are tapered for perfect pinion alignment. American Automotive u bolts are manufactured for maximum clamp force and are guaranteed for life. Made of cold drawn certified 1541 carbon steel OEM factory material with grade 8 hardware, American ubolts embody extreme strength and maintain OEM handling characteristics. These square ubolts are engineered to clamp 2.5 inch wide leaf springs and are 10.5 inch extra-long measured from the bottom of the bend to the bottom of the threads. American u-bolts provide an even distribution of pressure to protect against premature spring failure and unwanted movement. Allowances need to be made for all overloads and aftermarket leafs. 5 inch thread can be cut down to fit many applications.
