Aeagle Front Upper Control Arm with Ball Joint for 1999–2006 Chevy/GMC SUVs & Trucks — Preassembled, Heavy-Gauge

The Aeagle K80942 is a replacement front upper control arm with integrated ball joint engineered to restore steering geometry and suspension performance on compatible 1999–2006 GM trucks and SUVs.

If your Silverado, Sierra, Yukon, Tahoe, Suburban, Avalanche, Escalade, or full-size Express/Savana shows uneven tire wear, looseness at the front end, or noisy suspension travel, a worn upper control arm can be the root cause. This single-driver/passenger universal unit arrives preassembled with a ball joint to simplify installation and returns the factory-style connection between wheel hub and frame.

How will this control arm affect steering and handling?

Replacing a tired or bent upper control arm re-centers the wheel alignment, reduces play in the steering, and stabilizes cornering response. You should notice a crisper steering feel and improved predictability during lane changes and braking.

• Restores correct caster and camber relationships for factory handling.
• Reduces front-end shimmy and steering wander on straight roads.
• Improves tire contact patch for more even tread wear.

What vehicles does the Aeagle K80942 fit and how to confirm fitment?

The K80942 is designed for many GM full-size pickups and SUVs from the 1999–2006 model years, including Silverado, Sierra, Yukon, Tahoe, Suburban, Avalanche, Escalade ESV/EXT, Express, and Savana. Always verify vehicle compatibility against the product listing and your OEM part number before ordering.

• Direct replacements for applications that list OE number 12475485 and RK80942.
• Works with 1500 and 2500 series models where specified.
• Cross-check with the vehicle’s VIN or parts database for exact fit.

What are the build quality and warranty details?

The arm is manufactured from high-grade materials and is subjected to impact, wear, and fatigue testing to meet durability expectations for road use. Aeagle supports the component with a 12-month limited warranty and inspects parts before shipment.

• Heavy-gauge metal construction for torsional strength and longevity.
• Preassembled ball joint to save install time and ensure correct seating.
• Quality control checks and a 12-month warranty offered by the seller.

How straightforward is installation and what should I prepare?

Installation is a standard front-suspension job for experienced DIYers or professional technicians: remove the old arm, transfer any reusable hardware if required, and torque to factory specifications. A wheel alignment after replacement is recommended to lock in handling and prevent premature tire wear.

• Requires basic suspension tools: sockets, torque wrench, ball joint press or appropriate separator.
• Expect roughly 1–2 hours per side for a trained mechanic; times vary by shop and vehicle condition.
• Plan a post-install alignment to restore proper toe, camber, and caster values.

Who this is for: Owners or mechanics working on late-1990s to mid-2000s GM full-size trucks and SUVs who need a reliable, preassembled upper control arm to replace worn or damaged originals. This part suits anyone restoring factory handling, stopping uneven tire wear, or preparing a vehicle for safe daily driving or towing. If you want a straightforward OE-style swap backed by inspection and a 12-month warranty, the Aeagle K80942 is a practical replacement choice.
