"Awesome control arms! My mechanic said 'Your Jeep is pretty much bulletproof now', and I just got the tier 1 arms! The people at the Core4x4 shop were really nice too. They were running behind on shipping, (which is understandable) so I decided to go pick it up because it was only an hour drive. They gave me a free $60 hardware kit for the inconvenience. Thanks Core4x4! You guys are awesome!!"

"I have purchased all front/rear upper/lower control arms. Front track bar and rear track bar. Quality is excellent and extremely durable, you can tell its built to last. Bent a bolt on the front track bar and called and spoke with Spence. He immediately sent me out new hardware plus some! Product is amazing but what really separates companies apart is their service and these guys are second to none. Thank you all!"

"Great quality arms in multiple styles and colors! I purchased the tier 3 short arms for my 98 xj. I can say that they setoff nicely so my 35 inch tires do not rub! The body of the arm is bulletproof. However make sure to maintain and grease the joints regularly as with any greaseable joint and they should last forever. I recommend this setup to any and all Jeepers looking to get away from the stock arm setup. Mechanic and bodyman of 12 years and my first choice for quality control arms!"

"Outstanding experience! I asked Core to build me a set of custom control arms that were larger/heavier than they normally build. They gladly accepted the challenge and turned out an expertly crafted and super strong product ahead of schedule. Fit and finish are excellent. Spence and Cameron were a pleasure to work with every step of the way. And all of this for a very reasonable price. I highly recommend these guys!"

"Excellent quality product and service. My l lower control arms broke and within the same day core 4x4 hooked me up with tier 2 arms and with the color I wanted. My Jeep rides better and has been solid for several months so far. 10/10 would recommend their products to anyone."

"Purchased Tier 3 control arms and rear track bar for a 2006 Jeep LJ. I had some technical questions and they were happy to answer them. They allow local pickup and were built to order same week. The order was wrapped and ready when I walked in and even gave a tour of the shop. Very impressed. Happy to do business with these guys."
