Just flip your fronts and use spacers on rear. Dont get those extenders. They are only lug centric and weak compared to what you have now.
I really agree with you there.. You shouldn't run spacers on the front of any type..
Just because of the added stress to the spindle bearings..
But I have 3 guys that I ride with that use the stud style spacers like the ones I posted the link to.. I also run them on the rear of my Warrior.
People are scared off by them cause they look kinda chickenshit, but trust me.. For the price they work just fine, and like I said.. Their stronger than they look!!
We ride hard, and on some pretty gnarly trails. Nobody has busted one yet, and one friend has them all the way around on his Blasty. No problems.. (They look kinda funny though)
I guess it would be your preference.. But don't be drawn in by fancy advertising, or the bigger is better BS..
I don't see why people would pay $200 for billet spacers, when these work just as well..
