Flashark AWD Coilovers for Infiniti G35x, G37x, M35x and M45x
Upgrade the stance and suspension response of your Infiniti AWD model with this Flashark height-adjustable coilover kit. It is specifically designed for confirmed G35x, G37x, M35x and M45x AWD applications and will not fit rear-wheel-drive models.
The performance-oriented spring rates and twin-tube shock design help control excessive body movement and provide a firmer, more responsive driving feel. The true rear coilover configuration combines the rear spring and shock into one assembly, creating a complete front-and-rear suspension setup.
Adjust ride height and spring preload during installation to achieve the desired stance and suspension setup. Actual ride height and ride quality will vary depending on the vehicle, wheel and tire configuration, alignment and installation.

Product FAQ
Yes. This application-specific kit is confirmed to fit the listed Infiniti G35x, G37x, M35x and M45x AWD models. It is one shared kit for these confirmed applications, but it is not a universal coilover kit. No. This kit is designed exclusively for confirmed AWD “x” models and will not fit Infiniti G35, G37, M35 or M45 RWD models. Compatible vehicles normally use the “x” designation, such as G35x, G37x, M35x or M45x. Check the vehicle badge, VIN information or drivetrain specifications. Contact us with your VIN if you are unsure. No. The Infiniti G37 Convertible is not included in the confirmed AWD applications for this coilover kit. A true rear coilover combines the rear spring and shock into one assembly instead of retaining the factory-style separate spring and shock arrangement. Professional installation is strongly recommended. Yes. The threaded coilover design allows the ride height to be adjusted during installation. The final ride height depends on the vehicle, wheel and tire setup, alignment and installation. No manual damping adjustment is advertised for this kit. The available adjustments apply to ride height and spring preload. Spring preload adjustment is not the same as shock damping adjustment. The front spring rate is 12 kg/mm (672 lbs/in), and the rear spring rate is 10 kg/mm (560 lbs/in). This provides a firmer, street-performance-oriented suspension feel compared with typical factory suspension. They can be used on a daily-driven vehicle, but the performance-oriented spring rates will produce a firmer ride than the factory suspension. Ride quality also depends on ride height, tires, alignment and road conditions. The ride height is adjustable, but the exact usable lowering range varies by vehicle application and installation. Avoid setting the vehicle excessively low, as this can reduce suspension travel and affect tire clearance, alignment and AWD axle angles. The package includes two front coilover assemblies, two rear true coilover assemblies and two height-adjustment wrenches. Yes. Professional installation is strongly recommended because this kit changes the vehicle’s ride height and rear suspension configuration. A four-wheel alignment is required after installation. This product includes a 2-year limited warranty against manufacturing defects. Normal wear, incorrect installation, collision damage and improper adjustment are not covered.
