A: is bentup the only place you can get them?
No, you can get the original bent ups at
Welcome to Trail-Gear Inc. Trail gear is also a supporting vendor. Ask for Chris, He'll take care of you.
B: how much was shipping?
Shipping is included in the order $300 out the door
c: i assume they are unfinished--does bentup powdercoat? and if so, how much extra?
They are unfinished. Most people who wheel will just spray paint them because it's easier to fix rock rash with spray paint then it is to re powder coat.
Soon Trail gear is suppose to offer sliders that are already powder coated for the same price (which includes shipping). Contact them for more info.
Visit their website for pics of the sliders. Good luck
