Upper and Lower Ball Joint Kit for 2001–2010 Silverado and Sierra 2500HD/3500HD Duramax Trucks

This upper and lower ball joint kit brings together four replacement joints and installation hardware for 2001–2010 Chevy Silverado and GMC Sierra 2500HD/3500HD Duramax diesel trucks. Designed for heavy-duty use, the Kryptonite joints use a greaseable metal-on-metal design for serviceable suspension maintenance, including applications with lifted vehicles and large off-road tires.

Machined bearing housings, induction heat-treated steel stud bearing surfaces and tear/wear-resistant boots support smooth joint operation. The joints arrive pre-greased with Chevron Ultra EP2 grease. Match the upper joint mounting style to your existing control arms: press-in for stock-style arms, or bolt-on where required by aftermarket arms.

Frequently Asked Questions

Which trucks does this ball joint kit fit?

This upper and lower ball joint kit fits 2001–2010 Chevy Silverado and GMC Sierra 2500HD/3500HD trucks with LB7, LLY, LBZ or LMM Duramax diesel engines. Match the upper joint mounting style to your control arms before ordering.

Should I select press-in or bolt-on upper ball joints?

Select press-in upper ball joints for stock-style upper control arms. Most aftermarket upper control arms use bolt-on joints, but confirm your existing arm's mounting style rather than relying solely on whether it is aftermarket.

Does each configuration include both upper and lower ball joints?

Yes. Both configurations include two upper ball joints, two lower ball joints and installation hardware. The selectable difference is the upper ball joint mounting style.

How often should these ball joints be greased?

Service these greaseable ball joints every 5,000–7,000 miles. They arrive pre-greased with Chevron Ultra EP2 grease; use only a small amount of grease per joint during servicing and avoid over-greasing.
