Thanks for the pics Shorty, does the spring hit the upper A-Arm when the suspension is at full drop?

Also from the looks of this full drop is less than stock as the shocks are mounted so much higher? Looks like they are a good 3 inches above the stock mounts? Also is this a YFZ450 shock or what is the E2E on this?

More info on leverage ratio:
Called Wayne at PEP yesterday about some other stuff and ended up talking about this as he also runs a LT500 for his duner bike.

Stock LT500 is 2.4/1 with the OEM rims (2/3 rims)
LT500 with 3/3 rims (from FSS) Leverage ratio is 2.5/1

Stock YFZ450 is 1.95/1 with the OEM rims (1/4 rims)
YFZ 450 with 3/3 rims (from FSS) Leverage ratio is 2.25/1

Wayne said running the stock YFZ450 shock will work on the zilla I just need to be mindful of the compressed length of the shock when re-locating the upper perches so it does not bottom out on the frame rails.

Having to make new upper perches will post up when completed.

thanks for all the help
