assemblies built with our forged pistons and high quality components from K1 Technologies. As your One Name. One Solution.™ company, it seems logical we offer complete
assemblies built from the highest quality products we offer.
This decision makes choosing components for your engine rebuild much easier and you can rest knowing that
the parts are made to work together to give the best performance possible.
These products have been matched for optimal performance by our engineers, so you can get the rebuild components that you need without taking the time to do all of the research. Click For A Short Video.
Forged Rotating Assembly Components
The relationship between K1 and Wiseco is an industry first. For the first time, rotating assembly components will be designed around each other from the inception, which.
enhances strength and eliminates mass. The professional engine builder will note the assembly balances well and fitment is exceptional requiring much less finish and balancing work.
All of our rotating assemblies come with pistons that are 100% forged and manufactured in the USA to withstand the heavy use of a professional racer or the more general use of a weekend racer.
These assemblies also have multiple choices of different crankshaft and connecting rod offerings from K1. All components sold by K1 are either Forged or Billet steel depending on your
choice in assembly. Either way you are guaranteed to have a rock solid bottom end that matches very well with our forged pistons.
Wiseco Pistons included in these assemblies are the same great pistons you can buy from us individually and are forged and machined in the USA to receive a full compliment of
power enhancing features. Light weight forgings, millimeter ring packs, extra-strength forgings, gas ports, optimized skirt profiles, skirt coatings, offset pins,
and a variety of other features are available depending on your application. Our sport compact pistons come with the Nitride Steel top and Napier 2nd XX ring packs for the ultimate in sealing and durability.
K1 Crankshafts are 4340 steel, core hardened and tempered to reduce stress and optimize tensile strength. The crankshafts are made with a nitriding process for hardening rather than induction heat treated.
This eliminates any softening between the journals and any post running deformation. Our crankshafts also feature straight oil holes for the best oiling
to the rod journals to insure you get the best crank for your money. Each K1 crankshaft is magnetic particle inspected and held to a maximum tolerance of .0002”
journal dimension. Counterweights are placed for optimal load reduction and ease of balancing making less work for you or your builder.
K1 Connecting Rods are offered in two different types, made from Forged 4340 Steel and Billet 4340 Steel.
Proprietary bolts produced by ARP to K1 specification have asymmetrical threads to equally load each thread when under pressure. Connecting rods are
shot peened for improved fatigue life and are finished in the USA using our state of the art Sunnen hones to exact specs.
The rods have double bridged caps to reduce housing bore distortion and there is no ridge between the blades acting as a stress riser. Rods are
weight-matched to +/- 1 gram and boxed with the individual rotating, reciprocating, and total weights conveniently noted for balancing.
A special wrist pin bushing material is also used with these assemblies offering friction reduction.
