These pistons have flat linear compression and digressive rebound with up to 0.056" of preload to generate low-speed control without excessive high-speed forace, helping you maintain grip over surface irregularities. Used on both dirt and asphalt cars, these pistons can generate the force numbers you're looking for to keep the left rear up or keep the front end sealed off. The amount of shim stack preload, shim thickness, and diameter are all able to be tuned to tailer the force curve of the shock.
