MOOG RK620889 Front Right Lower Control Arm and Ball Joint Assembly

In this review of the MOOG RK620889 front right lower suspension control arm and ball joint assembly the bottom line is simple: it is for owners of late 2000s to mid 2010s GM fullsize trucks and SUVs who need a direct-fit replacement that prioritizes strength and corrosion resistance. The reviewer found the part engineered for long life, with heat-processed components and added rust protection that help it withstand road grime and salted winter roads. It installs with precision tolerances intended to make steering alignment straightforward, which is the single biggest reason a DIYer or technician would choose this assembly.

Key Features

• Compatibility: Covers a wide set of GM trucks and SUVs from 2007 through 2016, making it easy to find the correct application.
• Easy to Install: Precision tolerances are designed to provide a correct fit out of the box and simplify steering alignment after replacement.
• Enhanced Structural Strength: Heat-processed components match or exceed OE requirements to resist premature failure under heavy use.
• Added Rust Protection: Coated studs and e-coated cast iron and steel inhibit corrosion from salt, road grime and oils for longer service life.
• Long Life Ball Stud: Ball stud shape is optimized to reduce fatigue, compensate for suspension sag and extend operational life.
• Quiet Operation: Engineering aimed at reduced noise and wear helps maintain a quieter front end over time.

Who It's For

This assembly is aimed at owners and independent mechanics working on 2007-2016 Chevrolet, GMC and Cadillac fullsize trucks and SUVs who want a strong, restorative replacement for a worn front lower control arm and ball joint. It suits vehicles used in regions with winter salt exposure because of the extra rust protection and coated components.

Those who should look elsewhere include owners of non-GM vehicles or those who require aftermarket parts with extensive performance tuning features; this part is engineered as a durable OE-style replacement rather than a performance upgrade.

Pros & Cons

Pros

• Direct-fit coverage for many GM model years reduces fitment guesswork for compatible trucks and SUVs.
• Heat-processed construction and coated components offer tangible resistance to premature failure and corrosion.
• Precision tolerances aid installation and steering alignment, saving shop time.
• Ball stud design targets long fatigue life under repeated suspension movement.

Cons

• Not a performance-oriented upgrade; it is intended as an OE-style replacement rather than for modified suspension setups.
• Buyers must verify exact fit for their trim and engine using the vehicle fit tool before purchase, as additional fit notes may apply.
