This pair of rear lower control arms restores the connection between your Infiniti's chassis and wheels, a critical link that every FX35 and FX45 from 2003 to 2008 relies on for balanced handling. Engineered as direct replacements for OE number 551B0CG000, they drop into the same mounting points as the factory arms, maintaining the suspension geometry that Infiniti engineers tuned for spirited driving on winding roads or steady highway cruising. The package measures 21 inches long, 12 inches wide, and 8 inches tall, arriving ready for installation without modification. Each arm weighs just over half of the total 11.6-pound package, a balance of rigidity and mass that helps the rear wheels track true over pavement changes. The set suits the 3.5L V6 and 4.5L V8 engines fitted to those model years, addressing clunks or wandering that signal worn bushings. When you replace these lower links, the rear axle reclaims its ability to articulate smoothly, conveying a composed ride around corners and under braking. The straightforward bolt-on design means you can bring back the sure-footed nature that once made every drive feel engaging.
