Details

Core 4x4's Crawl Series 4-piece rear control arm set replaces all four worn factory stamped-steel arms on the GMC Yukon XL 1500 (2000–2006). The factory arms use soft rubber bushings and a fixed length, so there's no way to re-align the rear axle or correct pinion angle after a lift or leveling kit. These Core 4x4 arms are a serious step up: DOM steel tubing and Rock Jock Johnny Joints at both ends of every arm for maximum articulation, with adjustable length to set rear axle alignment and pinion angle back to spec.

Includes: Rear upper control arms (pair) and rear lower control arms (pair); 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
Joints — Rock Jock Johnny Joints, both ends (every arm)
Adjustable length — for rear-axle alignment and pinion-angle correction
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 arms. If you ever need replacements down the road, the matching kit is available separately.
Running a lift? The 5-piece rear kit (CRL-G-800-YXL-RK5) adds the adjustable track bar to recenter the axle side-to-side.

Parts:

Upper forged Rock Jock Johnny Joint, right-hand — CE-9112N-22 (1 per upper arm, 2 for the upper pair).
Upper forged Rock Jock Johnny Joint, left-hand — CE-9112NL-22 (1 per upper arm, 2 for the upper pair).
Lower forged Rock Jock Johnny Joint, right-hand — CE-9114 (1 per lower arm, 2 for the lower pair).
Lower forged Rock Jock Johnny Joint, left-hand — CE-9114L (1 per lower arm, 2 for the lower pair).
Replacement hardware kit — CRL-G-800-RS4-HWK.

Fits:

Chevy Tahoe (2000–2006)
Chevy Suburban 1500 (2000–2006)

The whole process was quick and painless. The products are top tier and when I reached out them for package update info, Korby Linscomb was very responsive, and got me the answers I needed the same day. Even when I emailed back to some additional info, he sent what I was looking for that same day. I love core 4x4 and will be giving them my business from now on.

Ordered a control arm and track bar kit for my WJ from Core 4x4 on Monday 7/28 and received it today, Friday 8/1. Im not a state or two away, im in CT aka the other side of the country. Communication is phenominal, emails were responded too in an hour or less. Parts arrived well packed, not damaged, and are great quality for my needs. There arent many companies left that service customers as well as Core 4x4 and i wont hesitate to check them out again if i need something else. Well done!

I contacted these guys on a Saturday through email and needed some control arms by the following weekend, Spence got back with me and told me he would make sure the order got shipped out on Monday, they got busy and wasn’t able to ship the package out so he got back with me that evening and upgraded my shipping for free and shipped out the next day, only because he told me he’d make sure I’d have them by the weekend! This company sticks to their word! The customer service from these guys are unmatched and they will have another lifetime customer here!

After ordering an upper and lower adjustable control arm kit manufactured by CORE 4X4 from a jeep parts distributor who's intials are E.T., they came with 3 of the threaded ends missing. After over 2 months of phone calls and emails to this E.T. company nothing was resolved. I finally decided to call CORE 4X4 myself and tell them my dilemma. I spoke with a very personable and professional gentleman named Korby, who is one of CORE 4X4's representatives, after a brief discussion of what I went thru he simply asked me for a picture and some measurements and the items I was missing and asked if I could cover ONLY the cost of shipping and I had my missing parts in exactly 1 weeks time. This company not only builds all it's parts in the U.S.A., they stand behind their products with great customer service and life time warranty. My experience with this company and their Rep Korby was fantastic. I would definitely recommend CORE 4X4 to anyone who needs parts for any 4x4 projects. You just can't beat their quality and service.

Recieved warrenty exchanges for my control arms last night couldnt be happier!!! Lets talk about the arms tho! Great quality arms in multiple styles and colors!!! I purchased the teir 3 short arns for my 98 xj. I can say that they setoff nicely so my 35 inch tires do not rub! As long as you can get a photo or video of broken hardware core will take care of you. The body of the arm is bulletproof. However make sure to maintain and grease the joints regularly as with any greaseable joint and they shouldkast forever. I had a few problems arise a year after purchase and after some troubleshooting spence was able to help get me the correct parts to get back on the road. I recommend this setup to any and all jeepers looking to get away from the stock arm setup. Alltogether i am Very happy with the performace of my control arms!!!! Mechanic and bodyman of 12 years and my first choice for quality control arms!!

Core 4x4 excels with precision and service and keeps nothing else higher in mind. Everyone I've met at the company is very honest and down to earth, 10/10 would recommend.

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.
