Repeat customer on these nerf bars. Easy install, looks great, and very sturdy

Very easy to install

I'm writing this review as it was unclear if this would fit on the WT version of Silverado 3500HD 2020 crew-cab. The Westin Traxx 4 Pro Nerf step bars, model 21-24135, fit perfectly for Chevy Silverado 3500HD 2020 crew-cab WT (work-truck). Be sure to double check model # to ensure fit, super easy install as truck already has welded nuts on cab under-body, just have to remove plastic speed nuts to expose the welded nuts to bolt on Nerf bar support brackets (total of 6 bolts holds brackets and 5 more holds the bar to the bracket so 12 bolts per side (plus a few more to hold decorative plastic covers to hide support brackets. Can be installed with only one person. Helpful to watch one of Westin's YouTube videos on how to install it as it's helpful to see it once before doing, though not necessary as directions are also fairly clear. All in all, very sturdy well built product, easy to install, highly recommend.

I was worried, after reading some of the reviews, that these wouldn't fit my 2021 Silverado custom. But it bolted right up to the rocker panel. I've never mounted nerf bars or running boards before. This took me a total of about two and a half hours to do. Once I got the one side on and figured it out, the other side was simple. I recommend having ratchet wrenches, as it would have saved me some time and scratches on my hands. Inside the mounting brackets are pretty tight. But I got it done with a ratchet barely on the nut and tightened the other side with a wrench. I'll see how these hold up for durability in a few months and try and update this review then. But they look great I think.

I’m running a 2021 Crew Cab Trail Boss with short bed. Both Westin and the Mexico production plant seem to have addressed the fitment issue. First, Westin now has 4 attachment points on the tubes. In my picture I point out where the 4th attachment point is located (not utilized for my install). It essentially coincides with the rear edge of the back doors. As it happens that final row also now lines up with an attachment point on the truck which brings me to the Mexico plant. They have pre drilled 5 or 6 bracket attachment points on the frame to accommodate a variety of steps. Added bonus they are threaded so no need for clips. So these bars are definitely now compatible with Mexico build trucks; also confirmed by Westin whom I called. Mexico produced trucks VIN # start with a “3”.The instructions are ok but brief. Here is the best way to proceed with install: First, the parts wrapped in clear plastic are for driver side and the colored plastic bags are for passenger. If you’re going to use the decorative plastic trim pieces attach them finger tight to the brackets using the smallest bolts and washers provided. Make sure the “Westin” logo is facing right side up. Next, get under truck and remove plugs. Starting from the front you will remove the very first column of plugs. As seen in my pictures, from there move back about 1’ 10” to the next column of plugs to remove. Then it’s back about 5’ 2” to the final column which is roughly the ¾ point on rear door. Hopefully these measurements will help if you want to preplan this install. Using blue Loctite mount the brackets loosely to truck using the larger brass colored bolts and washers. After this you should tighten down the plastic trim pieces. Attempting this after installing tubes there is limited room to work. Slide them upward and tighten down snug but don’t overdo it. Now install tube to brackets. If you’re alone the easiest thing to do is start at the middle bracket. Balance the tube in your lap and scoot up near the truck, then bend your knees to raise the tube into position and for balance. Using the black bolts, washers and blue Loctite, finger tighten to that middle bracket. Now it will remain in place for you to finger tighten the other 2 brackets. Everything is still loose at this point so plenty of wiggle room to line up holes. Once attached to all 3 brackets, slide the tube out away from the truck towards yourself until it stops and then tighten bolts. This ensures the steps are level and flat. Finally, work your way under the tubes to tighten brackets to truck frame. You’re done. 1-2 hour job depending on skill level and/or Murphy’s Law.The steps look good. They are a cheap, basic set but get the job done. They do offset the benefit of having a 2” lift so keep in mind if you off road. They hug pretty close to truck and you can’t really stand on them with doors closed. 4” isn’t much width but enough to get your foot on especially if you step in kind of parallel with the truck. The step area is some kind of ABS plastic with knobs and grooves for grip. Seems to work but non-skid or hard rubber would be better. I like the gloss black finish because it matches my truck trim but keep in mind these are not matte like most sets. At the price you really can’t complain too much. There are better sets out there but cost becomes a factor. These will do me just fine.

I liked everything about them

I bought these thinking that they would last longer than a couple years. They started rusting right after I’ve had them on for a year. I am very disappointed. Both sides rusting in the same spot and someone else I know bought the same ones and have the same rust spots. Buyer beware!

These are really nice. They do not detract from the look of my truck. They make it so much easier to get in my Trailboss. Now I don't have to run 50 yards and jump to get in my truck. 6'5" husband like them too.

fit perfect on 2020 Chevy 3500HD. they sit nicely on the truck without jutting out to far. easily installed within an hour.

Looks good fits perfect

One year old and rusting out
