E Series Pistons The E Series are a forged from lightweight, 4032 alloy, yet feature prices that are comparable to cast units. Pistons incorporate forged side
GSX Series Pistons Top-of-line forged pistons include all of the features of the SX series with the addition of larger, deeper CNC valve
reliefs, additional CNC milling for weight reduction in non-critical areas and patented “X Groove” skirt for improved cylinder and ring life. Pistons, which are machined for 1.5mm, 1.5mm and 3.0mm piston rings, are sold in sets of eight complete with high strength piston pins. Rod Wrist Piston Comp. Comp.
