Classy bumper
Hopefully the bumper has the correct size sensor holes, so I don’t need to make any adjustments. I am waiting for which shipping company is bringing it to Alaska, Span Alaska, Lynden, Carlile, some other shipping company on a container ship ir truck it up the Alcan hwy

Great Bumper, but needs some design review
The bumper is heavy duty and looks nice. One very irritating issue though... When installing the brackets for the bumper, found that the slots punched were too small. I had to ream the slots out to allow the factory stock bolts to fit through and bolt to frame. This issue added a couple of hours of installation time. plus a trip to the hardware stock to purchase reaming bits that fit drill to open up the slots. Once this was done, installation moved along better. Also wish that Chassis Unlimited supplied some photos in instructions to help identify the proper steps.

Nice looking bumper.
This bumper is tuff, well built and nice looking. Made of sturdy materials ready to assemble and install on your rig. The welds are layed well and the textured coating adds to the look.

I have had this bumper installed for a few months now. I like the look and it is really well made. A 12,000 lb winch makes for tight fit.

Chassis Unlimited Octane front bumper
Over all I am pleased with this bumper. The craftsmanship is exceptional and quality is outstanding. The fit is lightly adjustable allowing for minor up and down and side to side movement. This allows the installer to tailor the bumper how they want it, high and tight to the grill, or left about 3/4” lower if they choose. The one thing I would change if I were to do this install over to make it a lot easier would be to cut the holes between the outer wings and center section larger. Currently, the holes are about 3-3.5” diameter making it very difficult to get your hand through it to install the nuts and bolts. There is plenty of material to open that hole up another inch. Other than that, everything went smoothly and took about 2.5 hours to install in my driveway. I opted to make some brackets to mount the factory fog lights as they fill the opening nicely and allow you to use the factory wiring. You will need to trim the mounts on the fog light to do this, but it’s a simple fix. Great product, solid bumper and simple install.

Review shared from Chassis Unlimited Prolite Winch Front Bumper; Black Textured (20-23 Silverado 2500 HD)
2022 LTZ - Dubbs105
Surprisingly good!
Solid bumper, good powder coating. Very symmetrical. Put it on a 2022 Silverado HD with a Duramax. You have to completely disassemble your original bumper and cut off some tabs used to hold the old plastic lower grill in. You'll also need to relocate the lower shutters if you have them. Expect to do some various plastic trimming behind the lower shutters for the winch to fit. An Apex 12K fits right into the space in front of the radiator without having to relocate the control box. Have a friend or an engine lift because with a winch and light installed, it is HEAVY. If you've never taken the face off your truck, expect to spend about 8 hours pulling everything apart and getting it all trimmed up. Loose fit your original bumper first, then put the ProLite in place. There are plenty of YouTube videos for taking the old bumper off. Once it's all back together and you start throwing P05AE codes, you'll probably need to replace the lower shutter unit.

Prolite bumper
Used the suggested shop by American Truck. Couldn’t be happier with the shop and the bumper. Looks like a factory upgrade. This thing is a tank.

2016 SLT - SickJoePick
My Extreme Chassis Attitude bumper is a bully
Just got back from Big Bend NP and thrashed my truck around the toughest roads. The bumper has the guts to hold up under harsh conditions. I would recommend lock washers and blue locktite on all connections as there was serious vibration and jostling going on. Needed more gap between fenders and bumper edges as the frame flex hammered the bumper against the fenders (it quit, self corrected over 120 miles of hammering!)
