05-14 Mustang GT Rear Lower Control Arm Kit

The 05-14 Mustang GT Rear Lower Control Arm Kit (MPN: M-5538-A) is a Ford OEM replacement suspension component engineered for 2005–2014 fifth-generation Mustang GT platforms. This pair of stamped steel trailing arms restores factory geometry and bushing compliance to the rear axle assembly, addressing wear-induced steering compliance, ride harshness, and suspension binding that develops across high-mileage or spirited-driving applications.

Each arm features greasable rubber bushings and natural steel construction, allowing field service and customization without integrated bearing preload constraints. The stamped design—lighter than forged alternatives—maintains factory compliance characteristics while supporting OEM suspension geometry and anti-squat tuning. Greasable bushings enable extended service intervals and accommodate thermal expansion in high-performance duty cycles, whether street cruising, road course work, or sustained acceleration runs. Replacement at the rear lower control arm stage prevents cascading wear to the axlehousing, differential mounts, and driveline components.

This kit is essential for operators and enthusiasts maintaining fifth-generation Mustang GT suspension integrity. Worn lower control arms introduce vagueness in directional response, increase tire scrub, and degrade brake feel—critical concerns in any duty or performance scenario. The pair configuration eliminates side-to-side imbalance and ensures symmetric roll stiffness and load distribution. Direct bolt-in design requires no frame modification, suspension geometry correction, or aftermarket adapter hardware.

Ford Mustang suspension components carry tight dimensional tolerances to maintain factory alignment specs and steering feel. Fifth-generation GT models (2005–2014) used this control arm architecture across standard and track-focused builds, making OEM-equivalent replacement the standard for reliability-critical applications. The greaseable bushing design also allows integration with modern polyurethane or spherical bushing upgrades if increased stiffness or reduced compliance is desired in future modifications.

Fits 2005–2014 Ford Mustang GT models. Weight: 15.94 lbs per pair. Dimensions: 6.25 × 6.25 × 28 inches.
