HAWK BROTHER Front Sway Bar End Links Kit for Chevy Silverado/GMC Sierra 1999-2006 — 2 PCS, OE-fit Replacement with Bushings

HAWK BROTHER front stabilizer (sway) bar end link kit K80631/K700539 is a direct-fit replacement set of two end links engineered to restore proper anti-roll performance on compatible GM trucks and SUVs.

These sway bar end links are built as a like-for-like service part for many Chevrolet, GMC and Cadillac models from the late 1980s through the 2010s, including Silverado, Sierra, Tahoe, Avalanche, Escalade and Express vans. The kit includes two complete end links with bushings and hardware where required and matches OE mounting points and overall length to maintain factory handling characteristics. Materials and machining reflect HAWK BROTHER's goal of balancing durability and value for routine suspension repairs.

How will these end links affect steering stability and body roll?

Replacing worn or loose sway bar end links helps re-establish the connection between the stabilizer bar and control arm, reducing unwanted body lean during cornering and improving overall steering feel. You should notice more predictable vehicle responses in turns and reduced clunking noises from the front suspension.

• Replaces fatigued or broken links that compromise anti-roll function
• Restores OEM-like pivot points to reduce body sway
• Improves vehicle handling consistency under load

What are the main installation considerations?

Installation is typical for front sway bar end links: raise the vehicle, support the control arm, remove the old link, and torque the new link to spec.
