i got a six inch lift for my 84 ford bronco witch is same as f-150 and i put the ad-a-leaf in and then took the stock riser block out and put the new one in but im not shur if i was supposed to leave it in because it seems like the axle should be pointing or more inlign with the drive shaft. im not shur if the is bad for it or wrong because it was not in the directions. thanks

You should need to re-use the factory block, underneath any additional blocks that come with a lift kit. The driveshaft need to point straight into the rear axle pinion, or you will get vibration in the driveline from binding of the u-joint at the rear axle yoke. You may also need to use a degreed shim to get a zero-degree driveshaft-pinion angle.

the stock block you are referring to is called a wedge..you do need that it gives the rear pitch it needs.
