SPL Parts Adjustable Rear Upper Control Arms (REAR)
2023–2026 Toyota GR Corolla
SPL RUA E210
Overview:
The SPL Parts Adjustable Rear Upper Control Arms are precision-engineered suspension components designed specifically for the 2023 and newer Toyota GR Corolla. These rear upper camber arms replace the factory bushings with high-quality spherical bearings, eliminating bushing deflection to sharpen suspension response and deliver a more predictable on-limit feel. Whether you are a spirited street driver or a track enthusiast, these control arms help you achieve improved handling, tire wear, and braking performance.
With a wide adjustment range, the SPL RUAs allow you to dial in the perfect amount of camber, especially beneficial for lowered vehicles. Advanced users with aggressive suspension setups can also fine-tune bump geometry when paired with adjustable lower arms, enhancing overall rear suspension dynamics.
Key Features:
These adjustable rear upper control arms incorporate premium materials and thoughtful design to maximize performance and durability:
- 6061-T6 Aluminum clevis and arm with anodized black finish for strength and corrosion resistance
- 6061-T6 Aluminum spacers and 360Âş clamp for secure and precise fitment
- 4130 Chromoly steel double adjuster, electroless nickel plated for durability and smooth adjustment
- Ti-6Al-4V Titanium 1/4-20 socket head Allen screws with anodized blue finish for lightweight strength
- FK PTFE-lined spherical bearings that are self-cleaning, US made, and provide low friction articulation
- Wide camber adjustability range to optimize suspension geometry and tire contact patch
- Clamp-style double adjuster located outboard for quick, easy, and jam nut-free adjustments
- Eliminates bushing deflection to improve rear suspension response and feedback
Construction & Design:
The SPL Parts Adjustable Rear Upper Control Arms are crafted from high-grade materials to ensure long-lasting performance under demanding conditions. The use of 6061-T6 aluminum for the arm and clevis provides an excellent balance of strength and weight savings, while the chromoly steel adjuster offers robust adjustability without compromising durability. The FK PTFE-lined spherical bearings reduce friction and self-clean to maintain smooth operation over time. The anodized finishes protect against corrosion and wear, maintaining the arms’ appearance and function.
The outboard clamp-style double adjuster design allows for fast and accessible camber adjustments without the need for jam nuts, making setup changes more convenient during track days or suspension tuning sessions.
Installation & Fitment:
These control arms are designed as direct replacements for the factory rear upper control arms on the 2023 and newer Toyota GR Corolla. Installation utilizes existing mounting points, requiring no cutting, drilling, or special tuning. The adjustable design enables precise camber settings to suit a variety of suspension setups, including lowered and performance-oriented builds.
