Performance Connecting Rod Kits
One Name. One Solution
800-321-1364 wiseco.com
Connecting Rod Kits sold complete with: Rod, crank pin, crank pin bearing, top
end bearing and thrust washers.
Double forged, Wiseco connecting rods maintain superior dimensional consistency through
improved grain flow. Shot peening eliminates residual stresses and smoothly blends the
rod forging surfaces. Extensive tests verify that shot peened rods provide more consistent dimensioning and surface finish than hand ground and polished rods. This produces
superior strength under heavy loads.

Crank pin bearing radial running clearance is optimized
to insure maximum performance.
Precision engineered oiling slots maximize rod strength
and bearing life.
Top and bottom end rod bores case hardened to 58-62
HRC to optimize bearing running surface.
Precision honing process ensures ultra round bearing
Double drilled small ends provide the piston
pin with extra lubrication and cooling - Reducing
distortion of top end due to thermal transfer
from the piston.
