Hydraulic Tailgate Installation Guide: Step-by-Step Instructions

Upgrade your vehicle with a smooth-operating hydraulic tailgate system. Our comprehensive guide ensures safe and efficient installation.

Benefits of Hydraulic Tailgate Kits

Effortless Operation: Replace manual lifting with gas strut-assisted motion.

Enhanced Safety: Prevents sudden drops and reduces physical strain.

Durability: Corrosion-resistant components ensure long-term reliability.

Universal Fit: Compatible with most pickup trucks, SUVs, and vans.

Tools & Materials Required

Hydraulic tailgate kit (struts, brackets, mounting hardware)

Socket wrench set

Torque wrench (for precise bolt tightening)

Drill with metal bits (if drilling required)

Safety glasses & gloves

Thread-locking compound

Pre-Installation Checklist

✓ Verify kit compatibility with your vehicle model (check OEM part numbers).

✓ Park on level ground and disconnect the battery.

✓ Clean tailgate hinges and mounting areas.

Step-by-Step Installation Process

Step 1: Remove Existing Components

Open tailgate fully and support it with a prop rod.

Detach factory torsion rods or manual struts (if applicable).

Label wiring harnesses if disconnecting tailgate electronics.

Step 2: Mount Hydraulic Strut Brackets

Upper Mounting:

Alounce bracket to pre-drilled holes near roof line.

Secure using M8 bolts (torque to 22–25 Nm). Apply thread locker.

Lower Mounting:

Attach bracket to tailgate hinge area.

Use included shims for alignment if needed.

Step 3: Install Hydraulic Struts

Extend struts fully before installation (prevents premature pressure loss).

Clip ball sockets onto upper/lower brackets until "click" is heard.

Critical: Ensure struts mirror each other at identical angles.

Step 4: Test & Adjust

Slowly lower tailgate to test strut resistance.

Ideal lift: 20–30% assistance on initial pull.

Ideal lowering: Controlled descent without slamming.

Adjust bracket positions if tailgate sags or recoils too forcefully.
