Found a couple of gems - actually IN Canada while shopping for lift components and such and thought I'd share.
Nothing wrong with shopping at tried and true National4wd but sometime found their prices a bit on the high side so went hunting...
Was looking for ARB bumpers and Old Man Emu coil springs and shocks and found:
www.arbcanada.com in Montreal (ex. $140 a pair for OME springs VS. National who wanted $260, bumpers are as good as US pricing)
Looking for Bilstein offroad shocks (like B6, 5100 or 7100) I found Essex in BC who actually shipped for free anywhere in Canada
www.bilsteincanada.com .
Finally, when pricing Magnaflow stainless systems came upon
www.hottexaust.com in Toronto - they have a "make offer" feature on their online shop - I recommend using it as you might be surprised with negociated pricing lower than US.
Maybe other Canucks could share their online Jeep part finds and we might get a sticky of CANADIAN resources someday?
