  • Find your 10MM sockets
Size: 20-26 Gladiator JT 4 door
These running boards provide easier access to the vehicle and do add an additional rugged look that complements the Gladiators design. Pros Heavy-duty steel construction-E-coated and powdered coated for durability. Non-slip steps for secure footing. Very easy bolt on installation with no drilling required. Custom fit for 2025 Jeep Gladiator model Great price$$ Value for the money is a no brainer. Cons The instructions were pretty much useless. It does add a slight amount of weight to the overall vehicle. Overall I would do definitely recommend this product. Even though the instructions were not very good. It took longer to find my 10MM sockets than it took to bolt it on. Update later if this changes but they look very good quality. I don't think they will rust at least not soon. ... show more

Size: 20-26 Gladiator JT 4 door
Outstanding product. Perfect fit for my Jeep Gladiator. Reasonably simple to install with a helper. Quality is excellent. Extra installation bolts, washers, lock nuts included if needed. Great price. One of the best recent purchases I’ve made on Amazon.

  • An excellent product. Great steps, and rock guards.
Size: 20-26 Gladiator JT 4 door
I was concerned these wouldn't be as well made as the OEM rock guards. They are every bit as good. They mount in all the manufacturers mounting points just like originals. They come with all the mounting hardware, and a lot of extra bolts, nuts, and washers to make sure you have everything you need to complete the installation. And a complete set of instructions that are not too difficult to follow! ... show more

I am not a mechanic and easily installed both within an hour. Previously it was just the rocker board. Now the jeep looks like a jeep.
