All new manufactured products are designed with engineered improvements that meet, or in many cases, exceed OEM designs.Cylinder Liner Design ImprovementsCylinder Head Design ImprovementsStress relieve liner while brazing water jackets This helps eliminate water leaksWe have improved the "Mae West" area while keeping the bore straight which reduces scuffingConsistent laser hardened surface area reduces wearControlled hone rate creates uniform cross-hatching, which reduces oil consumptionNew design stud boss reduces bore distortion and stud boss cracksBy eliminating large core plugs, HKEC eliminated the largest cause of water leaksEducate customers to torque outboard crabs firstControl fire face thickness which reduces thermal fatigueRedesigned internal water flow to a radial design. This eliminates hot spots which prevents fire face cracks.High strength ductile iron headsInjector seat cracks eliminated by casting changeBridge seat cracks eliminated by casting changePremium PistonHardened upper wear groove significantly reduces ring groove wearTin plated skirt aids lubrication during break in and reduces scuffing tendencies"Fat Boy" Connecting RodBlade:Slipper surface is micro-polished to reduce wear of the fishback bearingIncreased radius at the toe end reduces bearing failuresFork:Forged steel baskets provide increased longevityIncreased radii at beam to basket reduces fatigue crackingStiffer rod at pin end reduces twist and bend
