IRONTREE Front Upper Control Arms with Ball Joints — 2007–2016 GM Truck/SUV Pair, Pre‑Assembled Greased

IRONTREE K80669/K80670 is a pre-assembled left-and-right front upper control arm kit with integrated ball joints designed to directly replace the OE units on many 2007–2016 GM full-size trucks and SUVs.

These two pre-assembled upper control arms (driver side K80669 and passenger side K80670) restore correct suspension geometry and steering response after wear, damage, or failed ball joints. Manufactured to meet OE fit and function, each arm includes a greased ball joint and corrosion-resistant finish. The kit covers popular models such as Chevrolet Silverado, Tahoe, Suburban, Avalanche; GMC Sierra and Yukon series; and Cadillac Escalade — saving time by delivering a matched left/right pair ready for bolt-in installation.

How do these control arms improve driving feel and handling?

Worn or loose upper control arms cause play in the front suspension, uneven tire wear, and vague steering. Replacing both upper arms with pre-assembled IRONTREE pieces restores factory alignment points and reduces unwanted movement so steering feels firmer and tires wear more evenly.

• Pre-assembled ball joints remove the need to press in separate components.
• OE-form geometry restores correct caster and camber locations.
• Greased joints reduce break-in noise and help longevity.
• Weight-matched arms maintain original ride characteristics.

Will these parts fit my 2007–2016 GM vehicle?

This kit is engineered for direct replacement on specific GM models and model years; proper fit depends on exact year and trim. Verify compatibility with your year, make, and model — the kit covers a broad range of full-size pickups and SUVs but not every sub-configuration.

How difficult is installation and what’s included in the kit?
