Coilover Type Shock Absorber
By definition, a Coilover is a type of shock absorber where the spring goes around the damper. A Coilover type shock absorber can be adjustable or non-adjustable. People often misuse the word “Coilover” to refer to adjustable suspension.
This is where the damper adjuster is positioned for more information see the damper adjuster info sheet.
The shaft is connected to the shims and a piston which moves through the oil as it moves up and down the body.
Covers the top of the body and the shaft to help stop dust getting into the internal components.
Springs come in various lengths and rates. These are marked on each spring in the form of 5 numbers. For example “18006” means 180mm long and 6kg/mm in spring rate.
These are simply a piece of rubber that is designed to protect the shock absorber from a “metal to metal” impact when reaching the fully compressed length.
This spring helps keep pressure on the main spring if you lower the spring seat. It’s ok if this spring is compressed or loose, its job is only to keep pressure on the main spring.
This is used to adjust the vehicles ride height. If you wish to change the ride height, do not worry if you have to pre-load the spring or have it sitting loose (untrapped) to achieve your desired ride height. This is perfectly fine. To adjust the spring seat, loosen the allen key and then twist the seat with the MCA C Spanner.
Holds oil and gas. Inside there is a floating piston that separates the gas from the oil.
Bottom Mount & Locking Ring
This is used to adjust the shocks length and wheel travel range. This is preset by MCA Suspension at a position that should suit most cars of the same model. If you wish to move this, please contact MCA Suspension first.
At the base of the body (only visible with the bottom mount removed) there is a 2.5mm allen key bolt DO NOT remove this bolt.
