im wrecked my sled with a bunch of different bumpers..and they all did their job perfectly.
IMO it just comes to price, and what you think looks better...
--Co-Be bumper is sick looking, but too much for most (~new $350)
--Skinz bumper is awesome and very well priced (~new $200)
--TCP bumper is toughest but hard to find, and if you do is still pricey ($350 new, around $200 used)
--Treedog bumper is strong as hell also, but more pricey then skinz (~i think their around $225)
X2 on the tcp bumper. My sled had it when i got it. That thing has taken some pretty good hits on trees and the only thing wrong is some small scratches in the powder coat. I love that thing. Except there is a lot of snow build up on my 08. The one above is different from the one i have.
