Wj Adjustable Short Arm Comparison

I want to know the difference between the JKS adjustable short arms and the IRO adjustable short arms. I'm looking into new control arms and I want to see if the JKS ones are worth the extra money. I will be replacing all my control arms and my rear a arm. One of the guys in my club told me to ask if either one specifically has Johnny Joints.

I'm in the same boat actually, trying to decide on the best adjustable shortarms. I am also curious about Johnny Joints, do they actually improve ride quality? or would the stock bushings from JKS be better?

The JKS arms pivot in the center in order to give added flex and use rubber bushings at each end for excellent noise, vibration and harshness isolation.

The JKS arms are extremely stout and offer a wide range of adjustability.

PM me for pricing - I have JKS on special with free shipping too.
