Nice ride. My advice is get those reputable brands instead of chap ayam. This is because if the ARB has not gone through a proper design, it might not able to sustain the stress and it might break into pieces. This might endanger urself.
Already got the 19mm , didn't like it. Felt too stiff and like it jumps over bumps instead of absorbing it.
There's a reason why cusco , TRD, whiteline chose 16mm instead of 19mm.
