Viola, Wisconsin based S&S Cycle has been building stroker cranks ever since George Smith was drag racing in the 1950s - "if anybody has it down to an art, then it is S&S," says Marketing VP David Zemla.
The company's latest efforts are aimed at the Milwaukee-Eight platform (2017 and newer big twins) and "open up a whole new level of performance for these engines. Stronger, more durable, and trued to a specification that others can only dream of, these new flywheel assemblies are the best of the best to build your high-performance engine around.
"Using heat-treated ASI 4140 steel, each assembly is harder and twice as strong as factory parts. S&S high-strength connecting rods are designed using Finite Element Analysis to eliminate weak spots and create a part that can handle substantially more power."
They are available in 4.375", 4.5" and 4.625" stroke with tapered or high-strength, full-width wrist pin to accommodate "even the most demanding of builds." Each of these flywheel assemblies are also available with or without the counter balancer gear.
"We’re particularly pleased with our 4.625" stroker crank and figure we could combine that with the S&S 128" Power Package and build a 131" monster."
