Overview
The Rugged Ridge 18320.21 is a pair of extended rear sway bar end links for the Jeep Wrangler JK, designed for vehicles with a 4-inch suspension lift. They attach to the ends of the rear sway bar and are made of corrosion-resistant steel.
The extended length is designed to suit a lifted Wrangler JK, and the links attach to the ends of the rear sway bar. They are a fit for vehicles with a 4-inch suspension lift.
Key features

- Designed for a 4-inch suspension lift
- Corrosion-resistant steel construction
- Sold as a pair
- Non-adjustable rear end link
Lift height and link length
Sway bar end links carry the bar’s motion to the axle, and a lift changes the angle they work at. Longer links are used on lifted Wranglers so the geometry stays closer to stock while the axle moves through its travel. A link that is too short or too long can bind, so measure the lift height before choosing a length.
After installation, check that the links move freely through full suspension travel and that the ball joints are not pinched against the axle or frame. Steel links resist corrosion well, but coated surfaces still need inspection for chips. Replacing the sway bar bushings during the same job is a common choice, and it keeps the links from working against worn mounts.
