How is the Aeagle K80942 constructed and tested?

This control arm assembly is produced from premium-grade metal and includes a pre-assembled ball joint to streamline replacement. Aeagle subjects each unit to impact, wear, and fatigue testing to help ensure consistent durability under normal driving conditions.

• Material: high-strength stamped or forged steel (depending on production run) for load resistance.
• Pre-installed ball joint: reduces installation steps and alignment risks from mixing parts.
• Quality checks: impact, wear, and fatigue testing before packaging.

What comes in the kit and what do I need for installation?

The product ships as a single front upper control arm with the ball joint already attached, intended as a universal driver- or passenger-side replacement. Installation typically requires basic suspension tools and a wheel alignment afterward.

• Kit contents: 1x front upper control arm with ball joint (driver or passenger universal fit).
• Tools commonly required: socket set, torque wrench, ball joint press or suitable separator, jack stands, and penetrating oil for stubborn fasteners.
• Recommended service: professional alignment after installation to correct camber/caster settings.

What warranty and quality assurance does Aeagle offer?

Aeagle backs this control arm with a 12-month warranty and inspects each unit before shipment. While the warranty covers manufacturing defects, normal wear and damage from collisions or improper installation are typically excluded—retain proof of purchase and document installation for warranty support.

• Warranty length: 12 months from date of purchase.
• Pre-shipment testing: each item is tested before it leaves the warehouse.
• Support tip: save your order details and take photos if you need to file a claim.
