Leaf Spring Lowering kit

[Killerinc]

Got a question about a Leaf Spring Lowering kit. I was planning on lowering my Challenger 2 inches in the rear.
Is the lowering blocks the only way to go?
Does this also mean i need to add a pinion angle shim, if so how much for a 2 inch drop?
thanks

Blocks are the easiest means of lowering. There also are two position front hangers, rear sliders, and leaf with minimum to zero arch and alternate eye mounts that can work together to achieve a drop.  For instance, Hotchkis uses an alternate front hanger that reduces height .75" and combine it with a berlin eye spring with .75" to achieve a 1.5" overall drop.

You may need to add a pinion angle shim. Depends on how far out you end up from where you started.

Thanks for the reply but is there a calculation like when you drop it with blocks 2" you need to shim it with a 1/2" for example.

I will look into those Hotchkis parts

There is no is calculation that I'm aware of or have ever seen. There are simply too many variables between vehicles, parts, and installation to have a standard adjustment.
