Product Description

The RS-R N123D Down Sus lowering springs are engineered for the AWD V37-chassis Infiniti Q50, covering the 2014-2015 3.7L and 2016-2024 3.0T models in Premium, Signature, Luxe, and Sensory trims. Designed as a direct drop-in replacement for factory springs, this set delivers approximately 1.2 to 1.4 inches of front drop and 1.0 to 1.2 inches of rear drop while maintaining compatibility with OEM shocks. Spring rates are 8.68 kg/mm front and 3.67 kg/mm rear, matched specifically to the AWD suspension geometry of the V37 platform.

This is the AWD-specific application -- RWD Q50 owners require N122D, and Q50 Red Sport 400 AWD and Sport 3.0T AWD owners require N145D. All four springs are included. Powder coated finish. Made in Japan and backed by RS-R's 3-year / 36,000-mile warranty.
