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.

CORE 4X4 Company produces/manufactures exceptional products. My rear upper and lower control arms and rear track bar were powder coated custom Fox “Shock Orange” for my 2024 Bronco Wildtrak. OEM looks minimal compared to the CORE 4X4 control arms. Plus they’re adjustable, serviceable and rebuildable. Shipment was very fast and packaging used custom foam wrapped around the arms and heavy duty boxes. Not even UPS could damage. Korby L. was great to work with and responded quickly with emails and product information. Great products. Great people from the State of Utah. All Made in the USA. 5 Stars!!!

I have bought a bunch of sets of arms, track bars and even had custom work done by Core 4x4. Just yesterday, Spence and Cam delivered an awesome cross member they designed and built for me! All of their products have been exceptional! I have personally seen their progression with design changes/updates. They truly take pride in their work and products. Quality control is second to none! They’ve also helped me diagnose issues with different jeeps I’ve had, as well as Dodge/Rams. These guys know their stuff! Really! I trust them whole heartedly and absolutely love their products/quality of work! I’ve referred many people, and will always continue to do so. Keep up the good work Core4x4!

Had a great experience with Core 4x4, I desperately needed a custom track bar and found out just a couple days before Easter Jeep Safari. Spence was a huge help and made it happen with plenty of time to spare. Their parts are top notch!

Excellent service, Prompt responses when needing technical assistance, Amazing looking parts that fit excellently. I would recommend them to anyone looking for suspension components. Also very well packaged when we received the shipment, which means no damage from shipping company!! We went with the Crawl Series double adjustable kit and it definitely looks killer on our build!!!

First of I just want to say Great customer service korby Has helped me from the start and has not let me down! Reached out to him again today and he was able to warranty some parts out for me.
As far as the quality of the parts.. excellent! The build quality is great. I can definitely tell a
Difference from the cheap oem rear control arms to these and the pan hard bar.
Color, From what I can tell it’s super durable been through a few mud holes on top of the daily road grime and after a quick wipe they still pop!
Overall I recommend. Customer service is everything for me and it’s definitely there at Core 4x4.
