RockJock's 1 in. body lift for Jeep TJ Wrangler, LJ Unlimited and YJ Wrangler vehicles allows for additional tall tire clearance without exceeding practical suspension lift heights. The RockJock billet aluminum body lift pucks are concave on the bottom side to allow the retention of the stock rubber body mounting pucks. This keeps the body isolated from the frame just like stock, so that no more noise or vibration will be transferred to the cab of the vehicle than would be stock. The aluminum pucks are powder coated black for durability, and all of the necessary, new, longer grade 8 body bolts are included in the kit. We highly recommend the use of the 1 in. raised heavy duty motor mount kit in conjunction with this body lift to keep all of your underhood and linkage pieces in line with the body where they belong. On a vehicle with a 4 in. lift and 33 in. tires, you can install the body lift and motor mount lift and efficiently clear 35 in. tires.

Installed the full kit on my XJ. Ride quality is night and day better than what I had before. The articulation on the trail is insane. These guys know what they are doing. Already recommended Core 4x4 to everyone in my club.

The quality and durability of the arms are the best. They are super heavy duty. And lifetime warranty is crazy

I’m extremely impressed with Core 4x4. The quality of their parts is outstanding — everything feels solid, well‑built, and engineered with real attention to detail. Shipping was fast and everything arrived perfectly packaged. Their customer service is just as good as their products: responsive, helpful, and genuinely committed to making sure you get exactly what you need.
Overall, a top‑tier experience. I’ll definitely be buying from them again. Specially thank you Mr. Linscomb from Core 4x4. Arturo M.

Customer service is top notch. They answered all of my questions and got me my tracking number for my packages. I just received both of them and the quality is next level. You guys are truly awesome.

I wanted to take a moment and give these guys a shout out, I’ve currently got, for my xj, their adjustable control arms, tier 4 adjustable track bar and adjustable leaf spring shackles. You can always count on a fair price, high quality products, and quick delivery. Keep up the great work guys, will definitely continue to shop with you

Korby was a great help with getting me a set of leaf springs for my Cherokee. Great customer service and an awesome product all made in the USA. Proud to support and rock their parts on my vehicle. 👍 …

I have nothing but good things to say about Core 4x4. I have the crawler series on my JKU and we take it all over the place. These parts handle everything we throw at them.
