Introduction
Welcome to your EVIL ENERGY Coilovers instruction manual. This guide provides essential information for the proper installation, adjustment, and maintenance of your new suspension system. Adhering to these instructions will help ensure optimal performance and longevity of your coilovers.
Compatibility
These coilovers are specifically designed for the Nissan Sentra B17 models manufactured between 2013 and 2019. Please verify your vehicle's make, model, and year match this specification before proceeding with installation. Professional installation is highly recommended to ensure correct fitment and safe operation.
Key Features
- Height Adjustable: Allows for a 2-4 inch lowering range, providing an aggressive stance and improved handling. This adjustment capability helps eliminate turning noise and enhances steering feel and response.
- Durable Coil Spring: Features heat-treated, high-strength steel springs with an anti-corrosion coating, ensuring extraordinary elasticity and durability. The springs are tested for a fatigue life of 60,000+ cycles. Front and Rear Spring Rate: 5kg/mm (280 lbs/in). Front Spring Length: 200mm & Rear Spring Length: 162mm.
- Twin-Tube Structure: Compared to mono-tube designs, the twin-tube structure minimizes friction to achieve sufficient stroke with less effort. This design provides enhanced stability during driving on undulating roads and contributes to a more comfortable long-term driving experience.
- Premium Materials: Constructed with a steel body, plate top mount, spring, lower mount, and piston rod, all made from high-quality steel. These components maintain powerful abrasion performance during movement, ensuring overall strength and durability.
Product Components Overview
The EVIL ENERGY Coilover Suspension Kit includes the following main components:
Installation Guide
Professional installation is strongly recommended for optimal performance and safety. Improper installation can lead to vehicle damage or personal injury. Always use appropriate safety equipment and follow your vehicle's specific service manual.
General Installation Steps
- Step 1: Measure and Determine Height. Before removing the old suspension, measure the current ride height from the center of the wheel to the fender lip. Determine your desired lowering amount within the 2-4 inch adjustable range.
- Step 2: Adjust Coilover Height. Use the provided spanner wrenches to adjust the coilover's lower spring perch to achieve your desired ride height. Ensure the locking rings are securely tightened after adjustment.
- Step 3: Install New Coilover. Carefully remove the old suspension components and install the new EVIL ENERGY coilover unit into the vehicle's suspension mounting points. Ensure proper alignment.
- Step 4: Secure Components. Reconnect all associated components, such as brake lines and sway bar links. Ensure all mounting bolts are tightened to the manufacturer's specified torque settings.
Adjustment
Ride Height Adjustment
Your EVIL ENERGY coilovers allow for a ride height adjustment range of 2 to 4 inches. This adjustment can be made using the provided spanner wrenches. Always adjust both sides of an axle equally to maintain vehicle balance.
Damping Adjustment
The coilovers feature damping adjustment to fine-tune your ride comfort and handling. Locate the damping adjustment knob (usually at the top or bottom of the coilover) and turn it to your desired setting. Refer to the product's specific instructions for the range of adjustment and recommended settings.
Maintenance and Care
- Regularly inspect coilovers for any signs of damage, such as leaks, corrosion, or loose components.
- Keep the coilover threads clean and free of debris to ensure smooth height adjustments. A wire brush and appropriate lubricant can be used for cleaning.
- Periodically check the torque specifications for all mounting bolts and adjustment locking rings. Re-tighten as necessary to prevent loosening over time.
- Clean the coilovers with mild soap and water, avoiding harsh chemicals that could damage finishes or seals.
Troubleshooting Common Issues
Noise from Suspension
- Loose Mounting Bolts: Check and re-torque all coilover mounting bolts to factory specifications.
- Component Contact: Inspect for any contact between suspension components (e.g., springs, shock body) and other vehicle parts (e.g., chassis, control arms). Adjust clearance if necessary.
- Improper Spring Seating: Ensure the springs are correctly seated in their perches and not binding.
Uneven Ride Height
- Incorrect Adjustment: Re-measure and adjust the coilover height on each corner of the vehicle, ensuring precise and equal settings for both sides of an axle.
- Loose Locking Rings: Ensure all height adjustment locking rings are securely tightened to prevent settling.
Harsh Ride Quality
- Damping Settings: Adjust the damping settings to a softer position. Experiment with different settings to find the optimal balance for your driving conditions.
- Preload: Ensure spring preload is set correctly according to the product's specific guidelines. Excessive preload can lead to a harsh ride.
