Details
Core 4x4's Camp Series 5-piece rear suspension kit replaces all four worn factory stamped-steel control arms and the worn factory track bar on the Chevy Tahoe (2000–2006). The factory parts use soft rubber bushings and a fixed length, so there's no way to re-align the rear axle, recenter it side-to-side, or correct pinion angle after a lift or leveling kit. These Core 4x4 parts are a serious step up: DOM steel tubing, a poly bushing at each fixed end, and a forged Rock Jock Johnny Joint at each adjustable end for increased articulation, with adjustable length to set rear axle alignment, side-to-side centering, and pinion angle back to spec.
Includes: Rear upper control arms (pair), rear lower control arms (pair), and the rear adjustable track bar; mounting hardware (bolts, nuts, and washers).
Specs:
- Upper arms — 1.5 in. o.d. × 5/16 in. wall DOM steel
- Lower arms — 1.75 in. o.d. × 5/16 in. wall DOM steel
- Track bar — 1.5 in. o.d. × 5/16 in. wall DOM steel
- Joints — poly bushing at each fixed end, forged Rock Jock Johnny Joint at each adjustable end
- Adjustable length — arms and track bar
- Lift range — 0–6 in. and up
- Made in the USA
- Lifetime warranty — bend it or break it, we'll replace it
- Wear items (bushings, joints) — covered for 18 months
Suspension Type — Standard or Autoride (Z55): Select at checkout. Z55 trucks have factory rear air leveling; the Autoride version includes the ride-height sensor mounting tab on both rear upper arms. If you're not sure which you have, check the RPO sticker in the glove box for a Z55 code.
Notes:
- Hardware is included with your kit. If you ever need replacements down the road, the matching kit is available separately.
- Running a lift? The 7-piece full rear kit (CMP-G-800-TAH-RK7) adds the rear sway bar end links to finish the rear.
Parts:
- Upper poly bushing — BSH-UPBH-CB, 9/16-in. bolt (1 per upper arm, 2 for the upper pair).
- Upper forged Rock Jock Johnny Joint — CE-9112N-22 (1 per upper arm, 2 for the upper pair).
- Lower poly bushing — BSH-LOBH-CB, 9/16-in. bolt (1 per lower arm, 2 for the lower pair).

I purchased upper and lower adjustable arms for my WJ and lowers were missing the spacers. I didn't know until 3 months later when I was installing them. With absolutely zero hassles they quickly sent me the missing spacers. Fantastic product and service! Huge thank you guys for the awesome service and parts!!! Customer service is quickly becoming a lost commodity and you guys gave me hope that it's still alive and well, you just have to buy from the right people... Thanks again for going above and beyond! 👍👍

Great company! I have used there products consistently with no complaints with quality you can see and feel. From my experience, their customer service is also amazing. Core 4x4 has no issues standing behind their already amazing products and will quickly and professionally solve issues may they arise. I will continue to be a customer.

Phenomenal company - very rare to come by in the automotive industry. Also very impressing. Let me start here. I got a set of yellow sway bar end links for my 19 ram DT (new body style) and let me tell you, I’m hooked. For numerous reasons. One the craftsmanship behind the product is unmatched for sure for without breaking the bank. 2ndly, they stand behind their product. Had a very minor issue and it was resolved in a blink of an eye!!! Insane. Just because of what i listed above i will forever spend my money with core 4x4! And i think you should too! I have no affiliation at all with this company besides being a consumer. I will be ordering my yellow UCAs and the rest of my rear suspension from them here shortly!
Korby on the other hand. The representative that helped me went above and beyond FAST. I hung up the phone with him, and with in no lie 3 minutes he was calling back with an answer. GREAT GREAT GREAT customer service, Korby you and core 4x4 are what give us hope in the car community! With much love and great health to you all!!

We have all shopped places where the person on the phone makes you feel like they don't have the time to talk to you the customer or answer your questions. I can tell you first hand that's not Core 4x4. They have the best customer service I have seen so far. They have taken the time to respond to all of my questions in a very prompt and professional manner, taking the time to answer each and every question I have had. Lets put it this way if Core 4x4 sells a product I am wanting for my truck I will buy it from them, I highly recommend Core 4x4.

To start off if you're looking to upgrade your control arms definitely hit this company up. Great product, easy install of the product, with three different tiers everything is priced pretty good, I'm a sticker guy and they sent a sticker for each arm each track bar and also three extra ones so the extra are on the Jeep the advertise them for sure. If you're reading this review I highly recommend you to check their website out.

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!

I want to share a truly positive experience.
I ordered a car kit consisting of two packages, but unfortunately one was lost during shipping with UPS. The situation could have become complicated... but it didn't.
The company manager was extremely helpful and professional: he personally followed up on the situation and did everything he could to resolve the issue, even sending me the package again without hesitation.
It's rare to find such attentive and reliable customer service these days.
My sincere congratulations on your professionalism and commitment: that makes all the difference.
