TEIN EnduraPro PLUS KIT Shock Absorber Instruction Manual

1. Product Overview

The TEIN EnduraPro PLUS KIT is a high-performance, OEM-shaped shock absorber designed to enhance your vehicle's ride comfort and handling. This kit is engineered to be compatible with genuine springs and upper mounts, making it an ideal choice for both replacement of worn-out OEM shock absorbers and for performance upgrades while maintaining the original ride height. It can also be used in conjunction with lowering springs for a customized setup.

The EnduraPro PLUS features a new 'sealed structure' manufacturing method, ensuring both high quality and cost efficiency. Its robust construction includes increased plate thickness at the mounting points for strut-type applications, providing strength superior to genuine parts and improving overall durability. The shell case, a critical component, is made from high-strength material, achieving approximately 1.5 times the tensile strength of OEM parts. Furthermore, a larger shell case diameter increases oil capacity, contributing to enhanced durability and stable damping force performance over extended periods.

This shock absorber utilizes high-performance damper oil with stable viscosity characteristics across a wide temperature range, ensuring smooth stroke operation and consistent damping force in various driving conditions. For superior corrosion resistance, the product undergoes a patented 2-coat, 1-bake powder coating process after surface treatment, making it suitable for use in snowy and coastal regions.

The EnduraPro series incorporates a Hydraulic Bump Stopper (H.B.S.) mechanism. This system converts impact energy during full stroke into thermal energy within the shock absorber, significantly reducing disruptive impacts on vehicle behavior. This also minimizes damage to the shock absorber itself, further improving its durability.

Featuring a dual-tube design, the EnduraPro PLUS ensures ample stroke with low rebound. It is equipped with a 16-level simultaneous rebound/compression damping force adjustment mechanism. By rotating the adjustment dial, users can precisely modify the shock absorber's characteristics to achieve their preferred ride feel and handling.

2. Key Features

• OEM Shape & Compatibility: Designed to match the original equipment manufacturer (OEM) shape, allowing for the use of genuine springs and upper mounts. This ensures a direct fit and maintains the vehicle's original ride height if desired.
• Enhanced Durability: Features increased plate thickness at the knuckle mounting points for strut types, providing superior strength. The shell case is constructed from high-strength material, offering approximately 1.5 times the tensile strength of OEM parts.
• Increased Oil Capacity: A larger shell case diameter compared to OEM parts results in increased oil volume, contributing to more stable and consistent damping performance over time.
• Superior Corrosion Resistance: Utilizes a patented 2-coat, 1-bake powder coating process with anti-rust paint, ensuring excellent durability and corrosion resistance, even in harsh environments like snowy or coastal regions.
• Hydraulic Bump Stopper (H.B.S.): This innovative mechanism converts impact energy during full suspension compression into heat, effectively absorbing shocks and minimizing disruption to vehicle stability. It also reduces stress on the shock absorber, extending its lifespan.
• Dual-Tube Design: Provides ample stroke with low rebound characteristics, contributing to a comfortable and controlled ride.
• 16-Level Damping Force Adjustment: Equipped with a precise adjustment dial that allows for 16 distinct levels of simultaneous rebound and compression damping force. This enables drivers to fine-tune the ride feel and handling to their personal preference.

Important: Before purchase and installation, always verify your vehicle's model type, engine type, drive system, year, and grade using your vehicle inspection certificate or caution plate. Please cross-reference this information with the manufacturer's official website to ensure correct product fitment, as product part numbers may change due to model updates.

4. Installation

Installation of shock absorbers requires specialized tools and technical knowledge. It is highly recommended that this product be installed by a qualified professional mechanic to ensure proper fitment, safety, and optimal performance.

4.1 Pre-Installation Checks

• Verify all components are present and undamaged according to the kit configuration.
• Confirm vehicle compatibility using the information in Section 3.
• Ensure the vehicle is securely lifted and supported on a level surface.

4.2 General Installation Steps (Consult a professional for detailed instructions)

1. Remove the wheels and access the existing shock absorber assembly.
2. Carefully disconnect and remove the OEM shock absorber and spring assembly.
3. Install the TEIN EnduraPro PLUS shock absorber, utilizing the genuine springs and upper mounts as designed.
4. Secure all mounting bolts and nuts to the manufacturer's specified torque settings.
5. Repeat the process for all four corners of the vehicle.
6. Perform a wheel alignment after installation to ensure correct vehicle geometry.

5. Damping Force Adjustment

The TEIN EnduraPro PLUS features a 16-level damping force adjustment mechanism, allowing you to customize the ride characteristics to your preference. This adjustment affects both rebound and compression damping simultaneously.

5.1 Adjustment Procedure

1. Locate the adjustment dial on the top of each shock absorber.
2. Turn the dial clockwise for firmer damping or counter-clockwise for softer damping.
3. Each click represents one level of adjustment. The total range is 16 levels.
4. It is recommended to adjust all four shock absorbers to the same setting for balanced handling.
5. Test drive the vehicle after adjustment to evaluate the ride feel and make further fine-tuning as needed.

Note: Start with the recommended factory setting (usually a mid-point) and adjust gradually. Extreme settings may affect ride comfort or handling stability.

6. Maintenance

Regular maintenance helps ensure the longevity and optimal performance of your TEIN EnduraPro PLUS shock absorbers.

• Periodic Inspection: Regularly inspect the shock absorbers for any signs of oil leaks, damage to the dust boots, or unusual noises.
• Cleaning: Keep the shock absorber bodies clean, especially after driving in harsh conditions (e.g., mud, snow, salted roads). Use mild soap and water, then rinse thoroughly.
• Bolt Torque Check: Periodically check the torque of all mounting bolts and nuts to ensure they remain securely fastened.
• Professional Check-up: It is recommended to have your suspension system professionally inspected during your vehicle's routine maintenance schedule.
