Kliková křídel 76mm zdvih kalená en40b ocel

Nitrided, 76mm stroke, 1.625″ “S” big end journal, for 1275/1300 non-S block.Forged EN40B steel nitrided cranks are considered the ultimate in specification, even over the “billet” type. This is mainly because the grain pattern of a forging follows the shape of the webs and bearings whereas the billet type is machined across the grain. We stock all the forged types. All have superior oil distribution galleries, and heat treated for maximum durability. All are machined to fit 1275/1300 non-S center main except C-AEG479 which is “S”.All cranks have been re drawn to benefit from latest technology by having the crank webs designed to reduce whip and resistance at high revs giving smoother running and easier balancing, plus being mass centre balanced.
