Since i heard from ARB that there isnt any OME shocks made for the Hilux 4x2 im still looking for one

Any Hilux 4x2 owners there who have their suspensions changed for better ride and so?

Does Bilstein or any other brands have shocks available for the 4x2? Hope there are some..

and btw, there previous models of Hilux pick ups didnt have aircon filters?
I can get a filter installed then right?

And my stock head unit sa hilux ko nasira ung cd reading capability, under warranty pa to right?

Thanks a bunch
