Use 45 weight make sure you have those black foam inserts for the reservoirs otherwise the shocks will leak. Great product, look awesome I've mine for over a year and no problem so far.
so i have to put the black insert into the reservoir? up to where do i fill them? i think i overfilled mine and i didnt put the insert into the reservoir so all 4 of mine are leaking and i am going to order a rebuild kit to get rid of the leak.
