Calmini is pretty pricey stuff, if you want to save some coin. You could get the Trail-gear 6.5:1 there 499. Cheaper than calmini and it has a life time warranty on it. Cant beat that.
I think it would have to do with your preference to brands, lots of Toyota guys dislike trail gear.
Has something to do with they borrowing marlin crawlers products.
RRO has some half assed shipping, seems to take quite a bit longer than other places.
