This 4-piece rear trailing control arm kit provides precise suspension geometry adjustment for Buick Rainier models from 2004 to 2007. Constructed from high-strength steel with a classic black powder-coated finish, each arm resists corrosion and withstands demanding road conditions. The rear lower arms feature an adjustable center distance ranging from 440 mm to 510 mm (17.3 in to 20.1 in) for customizable alignment, while the rear upper arms offer a fixed center distance of 443 mm (17.44 in). Heat-resistant urethane pivot bushings enhance durability and reduce deflection under load. By improving suspension response and minimizing bump steer, this set promotes even tire wear and predictable handling for street, track, or drift applications. The kit includes two rear lower trailing arms and two rear upper trailing arms, all engineered for direct replacement with no modifications required. Package dimensions are approximately 57.3 cm in length, 23.1 cm in width, and 11.5 cm in height, with a total weight of 8,950 grams, ensuring robust construction and long service life.
