Product Details
These SF Racing Sport coilovers fit the 2017+ Infiniti QX50 AWD (J55/P71A). They are the best coilovers available for street-driven cars. SF Sport Coilovers were designed to give a wide range of ride height adjustability without reducing the spring travel. Each corner of the car has 32 levels (or clicks) of damping adjustability. This combines both the rebound and compression into one adjustment knob. The coilovers also use rubber top mounts to help reduce the noise that typically comes with high performance aftermarket coilovers. SF Coilovers come standard with an anodized coating to protect against rust and corrosion caused by extreme use and harsh external elements.
SF Racing parts are manufactured from high quality products sourced from around the world while still maintaining a very affordable price. SF Racing Sport Coilovers are the perfect setup for your daily driver.
