Schelle 12mm Flat 3+1 Shock Pistons with split hole sizes achieve a unique damping progression unlike a traditional piston. For the case of the 3+1 pistons, the added +1 small 1mm hole gives the shock lighter initial damping to prevent wheel hop, and to prevent the shock from binding up after huge landings. The 3+1 pistons are especially effective when using the Associated Kashima Coat optional shock bodies. The Kashima coat bodies tend to have a thicker damping feel because of the thickness and type of coating used.
Precision CNC machined, these pistons feature 3 x 1.4mm holes, and 1 x 1.0mm hole with a flat profile. These pistons are sold two per package and each pair comes with the Schelle Shock Piston Tuning Guide. The Tuning Guide explains the handling characteristics of each piston going from the lowest damping (low resistance) to highest damping.
These pistons are great in 2wd front OR rear (recommended 32.5 front, 30 wt rear oil).
