Details
Core 4x4's Cruise Series rear sway bar end links replace the worn factory links on the Chevy Avalanche 1500 (2002–2006). The factory links use soft rubber bushings and are sized for stock ride height, so after a lift they sit at the wrong length and the sway bar can't keep the body flat the way it should. These Core 4x4 end links are a serious step up: 0.75 in. solid cold-rolled steel, fresh poly bushings at both ends, and built to the exact length for your lift — or stock height — so the sway bar does its job again.
Includes: Rear sway bar end links (pair); mounting hardware (bolts, nuts, and washers).
Specs:
- Material — 0.75 in. solid cold-rolled steel
- Ends — poly bushings, both ends
- Built to length — for your selected lift size (stock–6 in., or custom), non-adjustable
- Made in the USA
- Lifetime warranty — bend it or break it, we'll replace it
- Wear items (bushings, joints) — covered for 18 months
Notes:
- Core 4x4 end links use a thru-bolt design that won't work with factory stud-and-nut hardware, so the install hardware — bolts, nuts, and washers — always ships in the box. If you ever need replacements down the road, the matching kit is available separately.
- Doing a lift? The 7-piece full rear kit (CRS-G-800-AVA-RK7) does the entire rear suspension in one order.
Parts:
- Poly bushings — BSH-TBBH-CB, 12mm bolt (2 per link, 4 for the pair).
- Replacement hardware kit — CRS-G-800-REL2-HWK.
Fits:
- Chevy Tahoe (2000–2006)
- Chevy Suburban 1500 (2000–2006)
- Chevy Avalanche 1500 (2002–2006)
- GMC Yukon / Yukon XL 1500 (2000–2006)
- GMC Yukon Denali / XL Denali (2001–2006)
- Cadillac Escalade / ESV / EXT (2002–2006)
- 1500-series only. Does NOT fit 2500-series HD.

Small business, family owned, made in the USA, lifetime warranty. Purchased Tier 3 control arms and rear track bar for a 2006 Jeep LJ. Simple website and easy to contact over phone and email. 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. They abrasive blast all raw materials to achieve a better surface profile for powdercoat to adhere and create a smooth, durable finish. I also noticed several CNC machines and a robotic welder they use for all their parts. A small outfit with a robotic welder? Their concern for quality is obvious and it shows in the parts they make. Very impressed. Happy to do business with these guys.

I bought the 16pc Cruise Series Adjustable Control Arm, Track Bar, Steering, End Link Kit to replace a worn budget 4" lift on my used JKU. These are top quality parts; very solid. Customer service is unsurpassed. They even matched prices on my order placed before the tax day sale. I made an error in ordering a drag link flip kit; they were quick to help me fix this too. There's peace of mind knowing these components are made in the USA. Thank you. 👍👍

Purchased a set of Trailing arms for my Ram 1500, quality is first class. I bought the ones with the Jonny Joints for more articulation and it appears from the construction I should get a lifetime of use, Zerk fittings are an added plus. Would defiantly recommend, and the the service team answered all of my questions.

First time buying from Korby @ Core 4x4 and it’s being nothing short of a great experience. I bought the non adjustable Trail kit for my 5th Gen Ram 1500 with a 2” lift. The welds look great, nice powder coat finish and quality bushing. Had some trouble fitting the grease nipples due to the powder coating but a thread tap would fix that. They fit easily and perform great. I felt the improvement straight away. No more wheel hop on hard acceleration which was my main reason for the purchase.
I was missing some smaller bushings needed for the 5th Gen and Korby’s custom service was on point, with responsive emails and mailing out the missing parts straight away. Very happy with their products and customer service. Highly recommended company👌🏽
