Description
aFe CONTROL Rear Sway Bar – 2009–2020 Nissan 370Z change axle roll stiffness so the chassis responds more decisively to steering input and carries lateral load with less body roll. This listing is built around aFe POWER part number 440-712001RL for the 2009–2020 Nissan 370Z.
A sway bar couples left and right suspension movement. Increasing its effective stiffness changes how lateral load is distributed at that axle, making it a genuine chassis-balance tool rather than simply a 'stiffer suspension' part.
What This Means on the Car
The correct bar depends on the rest of the setup. Tires, spring rates, dampers, alignment and front-to-rear grip all influence whether additional front or rear roll stiffness improves the car. Adjustable bars add another tuning variable through different end-link positions.
Fitment & Part Numbers
Application: 2009–2020 Nissan 370Z
aFe POWER part number: 440-712001RL
Fitment can differ by engine, drivetrain, trim, factory equipment, emissions configuration and production date. Match the part number above to the vehicle before installation; where aFe publishes SKU-specific installation or emissions requirements, those requirements take precedence.
Legacy Racing Enthusiast Perspective
For performance use, we choose sway bars to solve a handling objective—response, rotation, stability or roll control—not simply because a larger diameter is available. That approach produces a more balanced car than treating every increase in stiffness as an upgrade. On the 2009–2020 Nissan 370Z, we would make the purchase decision around the limitation this component addresses and how it fits with the car's current and planned modifications.
