These Cylinders feature an oversized 1 1/8″ shaft which makes the cylinder 40% more stronger than the competition cylinder. The cylinder staft is machined at the bottom to use all standard cups. What makes this cylinder different is not only the larger shaft, but the unique seal design. It has two major seals in the piston head. First, is the poly-pak seal, then a white o-ring backer seal. These are the cylinders we use in out competition vehicles.
