AURFA-SFX Full Coilover Kits
The AURFA SFX series adopts height-adjustable single-tube gas-hydraulic design. The greatest improvement is it separates the damper oil and nitrogen effect. One of the defects of multiple-tube gas-hydraulic shock absorbers is it mixes oil and nitrogen, and the pressure tends to be released unevenly which leads to abrasion and deformation of the steel core that cause the leak of the damper oil.

The AURFA SFX series damper adopts the design of 54mm super-large diameter and is made of intensified aluminum alloy. It greatly increases the volume of damper oil and provides excellent efficiency of heat spreading, which avoids air bubbles and ensures stable quality of damper oil. The shock absorber works well even when the car is being drove fiercely.Each type of AURFA SFX series shock absorber is designed specifically for the car type and. It has passed strict damper modulus test configuration, with. AURFA SFX series coil spring configuration, the car turns smoothly at winding courses. AURFA SFX series has high performance as a top-quality shock absorber.

As of safety, most original shock absorbers, designed for providing comfort for passengers, are not capable of truly reflecting the road situation, not to mention the G-force which dramatically increases when dodging or passing winding courses。The imbalance could lead drivers to making incorrect judgment. On the contrary, competition-level shock absorbers focus on control sensitivity rather than comfort and do not meet needs of most drivers. AURFA SFX series has qualities of both street and sport cars. It allows the driver to enjoy driving, no matter on winding courses or urban streets. If you are tired of the boring driving journey, AURFA SFX series will let you rediscover the connection between driver and cars.

 STEP 1
Lower the spring-seat and fixed-plate, make it has enough space for the upper mount completely falls on the damper. Firmly fix the upper mount to the damper.

 STEP 2
Place the spring in between upper mount and spring-seat. Winding up the spring-seat to make the spring disables moving up and down, but still can be easily revolved.

If there is space remained between the spring and spring-seat, it might cause scratching sounds during vehicle is moving.

If the spring-seatis over wound, it would make the spring  be in over-pressed status which can change the normal performance of the spring, and cause uncomfortable  bounces during vehicle is moving.

 STEP 3
After make sure the postion of spring-seat, use the wrench firmly  wind the spring-seat and fixed-plate in opposite way. 

 STEP 4
Keeps a record of the length between upper mount and  spring-seat of the first assembled shock. The pair of corresponding〈front / rear〉shocks should have the same setting.

 STEP 5
The distance between upper fixed-plate and lower fixed-plate suggested remain 4-6cm ; and the main body of damper should be wound into Lower Mount(bracket) at least 3cm.

 STEP 6
During installing shocks, the nuts of Upper Mount need not to be bolted to the bottom. After the whole installation process is done, and the vehiecle is completely put down on the ground, bolt the nut at last.

1. Bolt the the Lower mount(bracket)  by turns until nuts are firmly wound.
2. Fix oil pipe , ABS pipe or other wire, make sure they will not be pulled by one an other.

 STEP 8 
After put on wheels and put the vehiecle on the ground, check the horizontal of vehiecle. (distance A= distanceB as the graphic in the right)

Adjust the fixed-plate to the final position, Make sure there is no space remain between fixed-plate and lower-Mount(bracket). Bolt the Upper-Mount to the vehiecle at last.

 STEP 9
After the whole installation process is done, you should do the wheel Precision, ensure driving safety.
