The Sentinel Front Bumper with stinger is built for drivers who want extra frontal protection and a more aggressive trail-ready profile without sacrificing clearance or breaking the budget. Made from 3/16-inch steel, the bumper uses a low-profile, high-clearance design that tucks tight to the frame to improve approach angle and obstacle clearance while keeping the strength required for off-road impacts and recovery use.
An integrated tube stinger adds an added layer of protection up front while maintaining a clean, purposeful stance. The bumper supports a recessed winch mount option (JL5611) and includes an integrated fairlead opening to help keep the winch protected and positioned for optimal pulling angles.
Auxiliary light mounts are located front and center for simple lighting upgrades. Reinforced, built-in recovery points are designed to handle winching and snatch recoveries with confidence.
Finished in a durable black powder coat over zinc primer, the Sentinel is built to resist corrosion and stand up to harsh use. From rock crawling to overlanding, this is a capable, affordable front bumper that installs clean and delivers function-first performance.

I recently ordered a set of control arms from Core 4x4, and the entire experience was absolutely top-notch from start to finish. The ordering process was smooth, the parts arrived quickly, and the control arms themselves are extremely high quality—solid construction, great finish, and clearly built to last.
I also want to give a special shout-out to Korby, the guy I spoke with during the process. His customer service was amazing. He went above and beyond to make sure I got exactly what I needed, answered all my questions, and made the whole experience stress-free. You don’t see service like that very often these days.
If you’re looking for high-quality suspension components backed by truly exceptional customer service, I highly recommend Core 4x4. I’ll definitely be buying from them again.

Great products they sell, got a crawl series long arm kit for my xj and it has held up quite nice, they are beefy, and for what ever reason they fail it has a great warranty with a customer service to match, when someone asks what control arm kit to buy I always recommend core 4x4

Very beefy items for a very reasonable price. Personally have CORE rear track bar and all upper control arms for my 04 Jeep TJ. Had a slight issue with control arm length and they went above and beyond to swap jam nuts to get me where I needed to be. Really have to appreciate a company like this.

Korby was extremely helpful in helping me find the right part for my truck. He was kind, knowledgeable, and patient while I asked a million questions. He also went out of his way to find the right shipping option for me since it’s tricky where I live. I’m looking forward to getting the parts so I can fix my truck and go adventuring again soon!

Beefy parts made and painted well, very fair pricing for what you get, and fantastic customer service to boot. Easily my favorite place to get suspension parts.

Great customer service. I got my front upper and lower control arms and hardware on Friday afternoon. It didn’t come with instructions so I called Core 4X4 and they immediately e mailed me the instructions. Also, the kit I got had the spacers missing so I called. It was late Friday by thus time but they took care of the issue first thing Monday morning and I got the spacers on Tuesday. Great company.

I couldn't have been more excited for the initial unboxing of these new Core 4x4 UCA's!
They appear to be so well built and just a true quality product.
Installation was a breeze and the initial testing with the forklift appears to have given me some additional flex with less binding on the rest of the components now that the geometry is back properly aligned.
Time will tell how they hold up on my near future off-road adventures but I don't have any doubt that they are up to the task!
