All new manufactured products are designed with engineered improvements that
meet, or in many cases, exceed OEM designs.

Cylinder Liner Design Improvements

Cylinder Head Design Improvements

Stress relieve liner while brazing water jackets This helps eliminate water leaks

We have improved the “Mae West” area while
keeping the bore straight which reduces scuffing

Consistent laser hardened surface area reduces wear

Controlled hone rate creates uniform cross-hatching, which reduces oil consumption

New design stud boss reduces bore distortion and stud boss cracks

By eliminating large core plugs, HKEC eliminated the largest cause of water leaks

Educate customers to torque outboard crabs first

Control fire face thickness which reduces thermal fatigue

Redesigned internal water flow to a radial design. This eliminates hot spots which prevents fire face cracks.

High strength ductile iron heads

Injector seat cracks eliminated by casting change

Bridge seat cracks eliminated by casting change

Premium Piston

Hardened upper wear groove significantly reduces ring groove wear

Tin plated skirt aids lubrication during break in and reduces scuffing tendencies

“Fat Boy” Connecting Rod

Blade:

Slipper surface is micro-polished to reduce wear of the fishback bearing

Increased radius at the toe end reduces bearing failures

Fork:

Forged steel baskets provide increased longevity

Increased radii at beam to basket reduces fatigue cracking

Stiffer rod at pin end reduces twist and bend
