I've been looking at the Summit and ERBE front assembly exploded views and comparing part numbers for what's the same and what's different.

As far as I can see, both have the same part numbers for suspension pushrods, a-arms, shocks, rockers.

Why is it that the ERBE sits with the A-arms parallel to the ground, whereas, the Summit sits obviously higher?

There's a reason for the difference but I must just be having a man look.

Any "pointing out the obvious" appreciated.
