The same high quality parts we use in our Smeding LS engines, now available in a balanced & ready to run rotating kit! Start by selecting how much horsepower you plan to make, followed by your engine block's bore diameter, what stroke crankshaft you want, and then your desired piston volume! All rotating assemblies come with coated tri-metal race main & rod bearings, and the correct piston rings for your horsepower goals. The crankshaft will also be digitally spin balanced to the weight of your new rotating assembly, on our Hines Legend balancer, ensuring smooth, trouble free operation for many many years!
