Awesome product and service! I even got some of their swag because it looked pretty darn good. I will definitely be going back and would suggest this business to others looking for quality control arms. Buy local!

I purchased a set of the Cruiser Series control arms for my Jeep Jk based on postive reviews from different Jeep Facebook pages. Ordered and 2 days later realized they had the very same exact arms on sale in the overstock section. Called them up and they refunded me the savings from my original purchase. Amazing, honest service. Can't wait to get them installed. Keep up the good work guys.

Have full upper/lower CA set on both front and rear axles on a 96 ZJ. These are the rubber bushing sets not joint sets. I have beat the hell out it in the Nevada desert for 2 years and has been great. I don’t go fast but I do articulate suspension a lot. Super solid and haven’t any issues. Just inspected the entire set recently due to some banging under it. Turns out the banging is lower rear shock bushings. Inspected each CA along the way nothing. Aside from dirt and obviously winter roads and what not still in excellent condition, bushings are solid like the day they were installed. I’ll add that I’m about tapped on a short arm at 4.25(less with settle) so the front CA’s get beat on just from that, still they’re like new. Paint is great condition, this set is red. I would definitely buy again. Another plus for me, Utah isn’t local necessarily, but it’s nice to support businesses closer to me.

2022 I ordered a 2023 Jeep Wrangler Rubicon in High Velocity yellow. Without any hesitation I knew I was going with Core 4x4’s 16pc Camp series suspension, powder coated in yellow. Compliments were a given from any and everyone that looked under my jeep. So beefy, I may have left some yellow paint on the rocks from Maine to Florida, but no bends or breaks. Customer service has been perfect each and every time I have needed something. Their warranty is top notch! Their communication is also wonderful. Might upgrade to the Crawl Series control arms where the Johnny joints are on both sides. Great all around company and a great team to troubleshoot your issue and come to a conclusion. Nothing bad to say about this company. Just love this suspension.

I have recently come to know Core 4x4 when I purchased a Jeep XJ and was looking for a place that had dedicated XJ suspension and components. Here is what makes them different than most other shops. All of their components are top shelf quality and they back it up if you break any of it. I was able to see their shop when I picked up an order locally and was impressed with their attention to detail and how they assemble and powder coat each part. I had an issue with a shackle and needed the threaded shaft to be shorter. I called in and talked to Kaden and he told me to come by and they would shorten it for me. When I got there, Kaden and Spencer (the owner) met me and talked about options and proceeded to make the right adjustments to fit my XJ. Told me if anything changes in the future and I need additional length, they would take care of me. So what really sets them apart from others is their Customer Service. Try calling in to any other Jeep suspension or part shop and see how they treat you. Been there - done that.
Will continue to do business with Core and their team. Getting that kind of service for just a shackle has me thinking I may need to replace my JT components with Core's. Thanks Guys for being helpful good humans!

Exceptional customer service. All my questions were asked in a timely manner and parts were replaced when an error occured. I encourage people to make purchases due to their exceptional quality products, but also because of their customer service. Will make additional purchases in the future.
