I'm planning to put some on my Prado and my Sorento. How much are the hydraulic shocks? Mayrun rin ba na gas type? I'm not familiar with shock absorbers and all I know is pag nag install ka ng heavy duty shocks eh pwede mo sila itaas at ibaba with the swtich of a button kundi minsan automatic na nade-detect yung terrain at naga-adjust nalang automatically. Pls. kindly pm me if you know any store in q.c. that sells these shocks and give me an idea on how much. Salamat.
