Hi bro can your shocks be paired with Honda city 09 original spring?

Now I'm having a problem that my absorber is become softer and softer after quite sometime of using it. I would like to have a harder absorber without changing the height of the car.

Does your absorber suit my requirement? What is the specialty of your absorbers as compared to other brand like GAB, APM performax and IMProve ?

If yes, please pm me the best price and details (the duration of customizing the absorber and place to install) for honda city 09. Thank you very much
