Pack of 50 lightweight machined shims for adjusting the AOE (angle of engagement) on AEG pistons when fitted between the piston had and piston body. Two different thicknesses are provided to allow for more precise AOE adjustment than is usually possible with other methods such as sorbothane pads, these can also be removed and refitted in different combinations as other parts are changed or upgraded to maintain the correct adjustment.

Designed mainly for use with LPE AOE adjustable piston heads, these can be used with other piston heads but care should be taken to ensure the piston head remains centered.

The red shims weigh approximately 0.09g each and the yellow shims weigh approximately 0.12g each, a typical stack of shims to make up 3mm of AOE adjustment will weigh well under 1g.

Each pack contains 25x 0.38mm thick red shims and 25x 0.50mm thick yellow shims.
