E Series Pistons GSX Series Pistons
The E Series are a forged from Top-of-line forged pistons include all of
lightweight, 4032 alloy, yet feature the features of the SX series with the
prices that are comparable to cast addition of larger, deeper CNC valve
units. Pistons incorporate forged side reliefs, diamond-turned skirts, forged reliefs, additional CNC milling for weight reduction in non-critical areas and
oil drainbacks, double valve notches, precision honed pin bores and are patented “X Groove” skirt for improved cylinder and ring life. Pistons, which
machined to accept 5/64", 5/64", and 3/16" rings. Sold in sets of eight, are machined for 1.5mm, 1.5mm, and 3.0mm piston rings, are sold in sets
complete with heavy-duty piston pins and double true arc pin locks. of eight complete with high-strength piston pins.
