Can't recall the costs, but the Zions is like 4X the cost of OE....and the OE on mine was changed around 95K just because...

I'd say take that extra money and use it for the hoses and such.
And or, if you're lucky like me, save the extra coin for the unexpected like the high pressure steering hose, I replaced 2X within 15K miles if my memory recalls. I was not a happy camper spending $$ on this $$$ hose
