Does anyone know how much the lower bumper insert costs? I haven't had any takers with Titan that wanted to trade their painted bumper for the chrome one so now I am looking into just buying the piece. Anyone know how much they run for?

Not sure but check this out:

Thanks for the link. I emailed them about it. Hopefully this is a solution for me :-)

I got the lower insert from Mossyperformance for $170. It is a T-rex brand.

Anyone have a photo of the lower insert?

I'm guessing the addition is for looks, possibly a distant second would be some damage protection from rocks, etc.
