2pc Front Lower Control Arm Ball Joint for Chevy Silverado 1999-2006

In this review of the 2pc front lower control arm set, the bottom line is simple: this pair is aimed at owners of 1999-2006 Chevy Silverado and GMC Sierra 1500 trucks who need a direct-fit, durable replacement that simplifies alignment and steering setup. The reviewer found the package - one driver side arm (K620265) and one passenger side arm (K620264) - useful for completing a front suspension repair in one go, and the most persuasive reason to buy is the combination of tested durability and precision tolerances that make installation straightforward.

Key Features

• Complete pair: Ships with both driver and passenger front lower control arms so a single purchase covers the full side-to-side replacement need.
• OE compatibility: Matches OE numbers such as 12477633 and 12478067 to ensure the parts align with factory fitment for Silverado and Sierra models.
• Tested durability: Undergoes impact, wear, and fatigue testing to help ensure the control arms hold up under typical driving stresses.
• Precision tolerances: Manufactured to tight dimensions to allow easier installation and to preserve steering alignment without extensive adjustments.
• Wide vehicle support: Available for both foreign and domestic nameplates, indicating a design intended for common replacement applications.

Who It's For

This set is best suited for owners and independent mechanics repairing a 1999-2006 Chevy Silverado or GMC Sierra 1500 with worn or damaged front lower control arms and ball joints. Because the package includes both left and right arms, it fits customers who prefer doing both sides at once to restore even handling.

It is less appropriate for someone seeking an OEM-branded part from a dealer or a performance-upgraded heavy-duty aftermarket arm; this product is positioned as a tested, cost-effective replacement rather than a specialty performance component.

Pros & Cons
