product details

This is a standard-size piston with additional teeth for elongated Gearboxes. The Spacer and screw (included) is required for use in elongated Gearboxes.

Due to the removed teeth, this piston will have correct AoE in the vast majority of Gearboxes, although some gearboxes may require a little more material to be removed.

The metal racks are visually straighter than most ACM pistons and sit in the piston body well. The rack has no wobble and is difficult to remove by hand.

Weight: 17.4g (without spacer), 22.2g (with spacer and screw)
Length: 66.55mm
Width (excluding rails): 18.67mm
Total Width (including rails): 21.98mm
Height (inlcuding main teeth): 20.8
Height (pickup tooth & body -- the tallest area of the piston): 21.10mm

This piston has a narrow inner diameter at 15.4mm, so it may not be compatible with some thrust bearings.
