Part #: IS - PRO - GRB. After achieving long - term success with basic coilovers, ISR Performance has launched a premium line of coilovers. These coilovers offer superior dampening control and overall performance, making them ideal for both street driving and track racing. They provide a comfortable ride while significantly enhancing handling. Key features include 32 - way adjustable dampening, a mono - tube design, and a spring rate of 8K/10K. The front comes with pillowball upper camber mounts. ISR Pro Coilovers use high - end Japanese bearings. Our basic coilovers were used in professional Formula D drift cars, and these Pro coilovers are an upgrade. What's in the box: 2 front coilover assemblies, 2 rear coilover assemblies, and 1 spanner wrench set. All ISR Performance products are designed for off - road use only. Note: ISR orders may take a day to process. If you need it faster, contact us directly.


Using the ISR Performance Pro Series Coilover Kit is easy. First, make sure your vehicle is parked on a flat and stable surface. Carefully install the 2 front and 2 rear coilover assemblies according to the included instructions. Use the spanner wrench set for proper tightening. For adjusting the dampening, you can set it to your preference with 32 different levels. This allows you to customize the ride based on whether you're on the street or the track. Remember, these coilovers are designed for off - road use only, so don't use them on public roads. When it comes to maintenance, regularly check for any signs of damage or leaks. Keep the coilovers clean and free from dirt and debris. If you notice any issues, contact ISR Performance for further guidance.
