The width is the same as OEM bearing and thrust washers 25.75 mm, the difference is that the Aluminum thrust washers are thicker by 1mm (no cut step) giving you more side to side protection, also the aluminum harden #7075 alloy is pretty hard material and will expand some as the engine heats up, also the DCS Trust Washers have been tumbled with no sharp edges to cut into the piston pin, if your not happy with your purchase I can offer a RMA and will be happy to refund your money.
