SCITOO Front Suspension Kit 4pc Upper & Lower Ball Joints for Chevy Silverado 1500 / GMC Sierra 1500 (1999-2006) 4WD/AWD

Elevate ride quality with SCITOO front suspension kit

Designed for late 1990s to mid-2000s trucks, the SCITOO 4pc front suspension kit brings renewed steering feel and steadier braking through fresh upper and lower ball joints. Built for durability on daily drives, highway cruising, and light off-road use, this kit is a practical upgrade for aging front-end components.

The set centers on two front upper ball joints (K6540) and two front lower ball joints (K6541). These parts are pregreased before shipping, helping you move from unboxing to a real-world road test with less initial maintenance. The kit is intended for a broad range of Chevrolet and GMC models, including Silverado 1500 and Sierra 1500 platforms, as well as closely related family members like Tahoe, Suburban 1500, Avalanche 1500, Yukon, and Savana variants.

What’s included and how it helps

In the box you’ll find the two upper and two lower front ball joints you need to refresh the steering and suspension linkage. Proper replacement can contribute to smoother wheel alignment feel, improved steering response, and a more controlled ride when signals and bumps are encountered on grade or gravel roads.
