Well i bought KYB shocks from plaza 3 months back for Rs.5100, some people were asking Rs.5700. But very happy with the performance.
Earlier had gabriels installed but ride was very still so replaced them.
One more option is that you exchange your shocks with kabli ones which will cost you around 2000-2500. But that is risky, sometimes they last very long and sometimes not even 6 months.
If you can afford it, buy KYB shocks and hopefully all your problems will end inshallah. I have a khyber too.
