SPL Parts Rear Toe Arms with Eccentric Lockouts for 2015-2023 Ford Mustang (SPL RTAEL S550)

Fits select 2015-2023 Ford Mustang models, including EcoBoost, GT, V6, Shelby GT350/GT350R/GT500, Bullitt, and Mach 1.

The SPL Parts Rear Toe Arms (RTA) for the S550 Mustang platform significantly increase chassis response and stability by eliminating factory bushing deflection. These arms provide an expanded range of toe adjustment, which is essential for maintaining performance alignments on lowered vehicles or track-focused setups. While factory eccentric bolts often slip under high cornering loads, the included SPL Eccentric Lockout (EL) kit secures your alignment settings with CNC machined plates and high-strength hardware.

Engineering for performance and weight savings, these arms are constructed from gun-drilled 2024 Aluminum main links and utilize a 360-degree Rotating Clamp design for fast, precise adjustments. The clamps are secured with blue-anodized Titanium socket head cap screws to minimize unsprung weight. For maximum durability, SPL utilizes FK Spherical Bearings with chemically bonded Teflon/PTFE liners, providing low-friction articulation and quiet operation without the maintenance of traditional rod ends.
