Beast Mode
Wether you’re hitting a deer or a leftist, this bumper will see you through the carnage. It’s 175lbs of steel armor for the front end. I had a mechanic put mine on and he said it wasn’t too bad. Had to do some trimming of the plastic OEM stuff and the bottom left and right wings were a pain in the ass. The bumper does not come assembled, so there are a lot of pieces that you have to put together like legos. The stock fog lights are no longer useful so you’ll need aftermarket 4” cubes or whatever. Each side of the bumper can hold 2-4” cubes per manufacture.

Awesome looking
Took some time to assemble. Needed some tiny hands to get in a few spots but all in all. It went together great and looks great. So glad I did it. Its a 3500 by the way it won't let me change my vehicle type

Great bumper
Very solid, welds are great quality. Very happy with this bumper. Finding a light bar for the center hole is pretty difficult though unless you want to by a $800 dollar rigid one. Besides that im happy.

So to start the packaging was top notch it arrived in perfect condition and everything was included. The construction was well done, and the powder coating immaculate.
