SPL Parts Porsche 981/991 Front Trailing Arms, manufacturer part number SPL TR 991, is a vehicle-specific control arms component. Match the exact part number, application, mounting position, adjustment purpose, and included components before ordering.
Key Features
- Any changes to front camber will change front caster necessitating adjustable arms for a proper alignment.
- Anti dive geometry can also be tuned with the use of our 6061 aluminum spacers.
- Billet Aluminum alloy 2024 hex rods are precision CNC machined and gun drilled to reduce unsprung weight while maintaining high strength and stiffness.
- SPL Front Caster/Thrust/Tension rods provide a wide range of front caster adjustment, allowing precise alignment for optimal turn-in response and to compensate for variances between left and right caster.
- Low-friction, smooth articulating FK Spherical Bearings eliminate the stock mushy rubber bushing to provide a more responsive steering feel.
- These arms are designed to be used with the OEM or OEM style front lower control arms.Our parts are engineered for maximum performance.

Alignment Components
Shop alignment components, camber kits, caster kits, and adjustable control arms at Black Ops Auto Works. Find vehicle-specific parts for correcting suspension alignment or preparing a performance setup, including toe links, adjustment cams, camber plates, and replacement mounts. Choose components based on your vehicle, suspension configuration, and measured alignment needs.

Toe describes whether the wheels point inward or outward when viewed from above. Each measurement has a different role, so the right correction part depends on which angle needs adjustment. This collection includes options from Black Ops Auto Works, AAD Performance, SPC Performance, Eibach, SuperPro, Whiteline, and other suspension brands. Adjustment capability varies by product.
