Front Left Lower Control Arm with Ball Joint & Bushing - Aluminium Fit

In this review of the Front Left Lower Control Arm with Ball Joint & Bushing, the bottom line is simple: this part is aimed at DIY mechanics and independent shops needing a reliable, OEM-quality replacement for compatible Honda and Acura SUVs. The reviewer found the aluminium construction and included cotter pin offer a neat, practical swap-in that fits 2003-2008 Honda Pilot and 2001-2006 Acura MDX models. Installation was straightforward and the part feels like a durable upgrade that meets or exceeds original equipment expectations, making it a sensible choice when the goal is long-term suspension reliability.

Key Features

• Compatibility: Direct fit for 2003-2008 Honda Pilot and 2001-2006 Acura MDX models, so buyers can replace the left front arm without custom modification.
• Material: Aluminium construction provides corrosion resistance and a lightweight option that helps preserve suspension geometry and handling characteristics.
• Complete assembly: Comes with ball joint and bushing preinstalled plus a cotter pin, reducing prep time and simplifying the installation process.
• OE interchange: Matches common OE/interchange numbers like RK621349 and 51360S3VA03, which helps verify fitment against existing parts lists.
• Quality standards: Manufactured to IATF 16949 and ISO 9001 processes, offering traceable production standards above typical aftermarket parts.
• Warranty: Backed by a 3 Year / 36,000 mile limited warranty from installation, giving added confidence after the purchase.

Who It's For

The primary audience is owners of 2003-2008 Honda Pilot and 2001-2006 Acura MDX who want a direct-replacement left front lower control arm that arrives ready to install. It also suits independent repair shops or knowledgeable DIYers who prefer parts that meet certified quality standards and come with a warranty for peace of mind.

Those who should look elsewhere include drivers who need a scaled performance upgrade outside OE geometry or vehicles with modified suspension where a vehicle-specific aftermarket performance arm is required. If a different model year or the right-side arm is needed, this specific left-front unit will not be suitable.

Pros & Cons

Pros

• Good fitment reports and easy installation mean less shop time for routine replacement.
• Solid build from aluminium offers durability and corrosion resistance compared with plain steel arms.
• Includes necessary hardware like the cotter pin and a preinstalled ball joint for a quicker swap.
• Manufactured to IATF 16949 and ISO 9001 standards and backed by a 3 year / 36,000 mile warranty.

Cons

• Not a performance-tuned arm, so drivers seeking altered suspension geometry should consider a dedicated performance part.
• Compatibility is limited to specific Pilot and MDX years, so fitment must be checked carefully before purchase.
