How to install TTC urethane cushion

You should loosely tie the coil spring and the cushion buffer using cable tie for the following types of cushion buffer: K, S, A, & B. At this time, be careful not to bend the cushion buffer. (It is not applicable for the following types: C, D, E, F)


1. Prepare tools

Prepare TTC urethane damping buffer, lifting device, soap water or WD (Water Displacement), and drawstring.

2. Lift the car

Use lifting equipment or an elevator (used in engineering) to lift the body up until the wheel is lifted off the ground.

3. Check the status of coil springs

Spring coil should be fully relaxed.

4. Clean the spring before installing

Spray lubricant, silicone or WD40 onto the coil spring makes the surface of the coil spring more smooth to easily install TTC Urethane cushion.

5. Install the buffer on the coil spring

Gently rotate the TTC Urethane damping pad until the grooves of the cushion align with the spring steps and the buffer is now in the center of the spring roll.

6. Check after installation

Make sure that the grooves of the buffer align with the coil spring. After checking, use drawstring to fix spring coil and TTC Urethane cushion.

Note when you install TTC Urethane Buffer

   Your car should park on a flat ground

   Choose a safe location for installation, no means running around

   You should turn off the engine to ensure safety

   Make sure the lifting device works properly before the gaskets enter the vehicle to ensure safety.

Check the status of the buffer after installation

Check if the coil spring fits into the grooves of the buffer. If not, you may have installed it incorrectly.

Check the buffer installation location

We recommend placing the buffer in the middle of the spring coil. In the general case, do not place the buffer on the top or bottom of the spring.

Check the size of the buffer

If the installed buffer has a size that is not compatible with the coil spring, the life of the product may be shortened. Please refer to the standard size table for each type of vehicle before purchasing and installing the product. Or contact our customer support center for specific advice.

Checking the installing location of the cushion buffer

We recommend that the position of the cushion buffer be in the middle of the coil spring. In general case, the cushion buffer should not be installed on the very top or bottom part of the coil spring.

How to fix TTC buffer into coil


1. Fix the upper part

Use the draw cord to fix the damping buffer into the spring in the second hole position from the right edge of the cushion as shown in the picture.


2. Fix the lower part

Using the cable tie, fix the damping buffer into the spring at the second hole position from the left edge of the cushion as shown in the picture.


3. Adjust the position of damping cushion

Adjust the buffer to the correct position between the coil spring if there is a deflection, then finish the job.

Do not over tighten when bundling with cable ties

The purpose of the cable tie is to prevent the buffer from moving around. If you tie too tightly, the O-shape of the buffer will be lost, which can degrade performance. See the red circle in the photo above
