SPC Performance Front Adjustable Upper Control Arm – ±2.0° Camber / ±1.5° Caster for 2009-2023 Chrysler 300 & Dodge Charger / Challenger (RWD Only)
The SPC Performance 66045 Front Adjustable Upper Control Arm is a premium tubular upgrade engineered for precise alignment on 2009-2023 Chrysler 300 and Dodge Charger / Challenger RWD models. This single arm (order two for a complete front kit) delivers up to ±2.0° camber and ±1.5° caster adjustment to correct alignment issues after lowering springs, coilovers, or performance modifications. Constructed from lightweight aircraft-grade aluminum with a low-profile adjustable ball joint and stock-style rubber bushings, it reduces weight while adding strength and adjustability. Bolt-on design installs in under an hour and dramatically improves tire wear, cornering grip, and high-speed stability. Sold individually perfect for street, track, or aggressive daily driving.
