The blocks are machined with a 4* taper to aid in drive line angle correction. Blocks are built to mimic factory blocks bump stop leg. These blocks have a captured U-bolt design to keep bolts from possibly spreading on the axle and have multiple spring pin positions. 5/8" pin.
Will fit most every application using a 3" wide spring and a 3.5" axle tube. WE have also used them on the older trucks with a 3.125 axle tube. This can be 78 up through the leaf sprung Super Duty.
