The rear sway bar keeps the GMT800 flat through corners, but it only works through the two end links connecting it to the frame — and after 20+ years the factory links are worn, clunking over bumps and letting body roll creep back in. Our Cruise REL2 replaces them with 0.75" OD cold-rolled steel and fresh poly bushings at both ends, built to the exact length for your lift — or stock height — so the bar does its job again.
The Escalade does daily-driver work — city miles, highway miles, the occasional tow. After a couple decades, the rear suspension is showing its age, and the fixed-length arms leave you no way to re-align the rear axle after a lift. You feel it as a clunk under throttle, a thud over expansion joints, and a vague, loose feel under load. Switching to Core 4x4 brings the rear back where it should be — with stronger, more durable construction built in.

Tier guide — Cruise (entry, this product) → Camp (mid, our most popular tier) → Crawl (top, extreme off-road, heavy towing, or high-HP builds). Cruise handles factory-power daily driving — lifted or not — and still outperforms much of the competition. Step up to Camp for serious trail and off-road use, or Crawl for extreme use, heavy towing, or high-HP builds — Johnny Joints handle that load better than bushings.
Hardware included — 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, washers, and fender washers — always ships in the box. Replacement hardware is available as a standalone HWK SKU if you ever need more.
Pairing tip — Doing a lift? These end links are part of our 7-piece full rear suspension kit — step up to the 7-piece kit to do the entire rear suspension in one order.
