At the peak of suspension technology, the TTX36 is Öhlins' stage-3 double adjustable. The TTX36 is the top choice for all mono-shock cars. The revolutionary twin tube design allows the compression and rebound valving to work completely independent of one another and by utilizing a solid piston, all damping is generated in the externally adjustable valves. Low internal friction, vast adjustment range and responsiveness even at the smallest of strokes are among its virtues. This shock also offers infinite valving possibilities, as well as many length combinations. The TTX36 comes as a coil over set up with hardware. It is also upgradable to 3 or 4-way adjustability. This is the BEST of the BEST! Sold individually.
