These rods were designed to give the most optimal rod/stroke ratio, while being super light weight and super strong. The better the rod/stroke ratio, the smoother the engine revs with less friction and thus better and faster! You can use these rods in both 3.0 liter setup with an L28 crank and our CH 29mm forged pistons, and also in a 3.1liter setup with an LD28 crank and our CH 27mm forged pistons.
L28 crank (39.5mm) + 139.5mm + 29mm = 208mm
LD28 crank (41.5mm) + 139.5mm + 27mm = 208mm
Length = 139.5mm, appx. 508g.
