Overview

The Rev9 Power Hyper-Street II Coilover is an entry-level suspension upgrade designed for the 2015-2019 Hyundai Sonata (LF), excluding Hybrid models. It features mono-tube shocks that provide a larger capacity of oil and gas for an improved ride quality compared to stock shocks and lowering springs. The coilover system offers 32-way adjustable rebound settings and full height adjustability by twisting the lower bracket, allowing for a drop in ride height without compressing the spring.
Show original supplier description
The Rev9 Power Hyper-Street II Coilover kit is engineered as an entry-level suspension upgrade for the 2015-2019 Hyundai Sonata (LF), specifically excluding hybrid variants. This system utilizes mono-tube shocks, which offer a greater capacity for oil and gas, contributing to a superior ride experience over conventional lowering springs and stock shock combinations. Featuring a front spring rate of 6 kg/mm (336 lbs/inch) and a rear spring rate of 5 kg/mm (280 lbs/inch), these coilovers are precisely rated to enhance handling performance. The independent spring tension design allows for custom stiffness adjustments without altering the ride height. Furthermore, the 32-click rebound adjustment enables users to fine-tune the damping force for a more comfortable ride or improved handling, while the full-length adjustment facilitates lowering the vehicle without compromising spring tension. Construction is of full steel alloy with aluminum hardware. Prior to installation, it is crucial to verify all hardware and properly preload the suspension to 10mm. A vehicle realignment is recommended after installation, and professional installation is highly advised. Rev9 Power requires installation by an ASE Certified Mechanic to honor the warranty.
