Regular Juice

[D-Maxtim]

Will the Juice box that I run on my 01 work on an 03? And does JK sell
a 4" exhaust converting kit to go from 01 Ext Cab Short Bed to
03 Crew Cab long bed? I am trying to weigh the Pros and Cons of this swap
as I have several mods on my 01 and would hate to have to start all over with
them on a new truck. I know that my Guages will transfer and my intake should
but was not sure about Juice and what to do about exhaust.

I read somewhere that the older juice needs an update to work on an 03. If you don't do the update one of the guages will not work IIRC.

Juice compatibility depends on version. If the LARGE plug has any 3 pins missing in a row on the outer corner, it needs these wires added. Best way I can describe it. If it is old, it WILL work, but the oil psi gauge will read zero and will need to have the code reset. Not sure if it will cycle out quickly or not.

I've had a few moving up in the world with trucks, and all it requires is a single pipe and a couple more band clamps (they suggest NOT reusing, but I often do) and you should be good to go!


Some private party buyers gobble these things up, but then again others have a negative opinion...
