The SHR Ronin Bushings made by Zak Maytum
The problem was, the other super springy bushings on the market were only super springy. No damping.
Cars have springs AND shocks for a reason! All the rebound with no control has a great effect on stability and adjustability.
If you try to tighten your trucks with no damping, a lot of the time the bushing just squishes, and you get no more tension.
