Blocks that bolt onto the spring pack for lift, usually 1 inch. They have no effect on the spring rate, hence the name.

Correct.
And they allow you to relocate the axle a small amount. 1/2 to 1 1/2"

Yep, and if you mill a taper on them they're better than adding shims to correct pinion angle. I've made my own to get good level height and pinion angle. 3/8" on the front and tapered 1 1/2" on the rear.

o ok thanks for that. so they are similar to lift blocks but alot smaller corect and can be tapered to reduce pinion angle. that might come in handy

And unlike lift blocks, you can use zero rates in the front because it bolts to the the spring pack.
