SBC T/S-3 4340 Forged Crank 3.750 Stroke

The SBC T/S-3 4340 Forged Crank with 3.750 stroke by Howards Racing Components is purpose-built for serious small-block Chevy engine builders targeting high-RPM performance and maximum durability. This crankshaft is engineered for competition-grade applications where stock components simply cannot withstand the demands of aggressive tuning, forced induction, or extended high-boost operation.

Forged from premium 4340 steel, this crankshaft delivers superior tensile strength and fatigue resistance compared to cast alternatives, making it capable of handling the violent reciprocating loads imposed by high-compression ratios and aggressive fuel mapping. The 3.750-inch stroke is a popular choice for SBC builds seeking increased displacement and torque output while maintaining reasonable piston speeds—critical for reliability when chasing horsepower above 7,000 RPM.

Howards Racing Components machines these cranks to exacting tolerances and applies modern metallurgical techniques to ensure consistent weight, perfect journal sizing, and minimal runout, all of which reduce vibration and extend bearing life. This SBC T/S-3 forged crank is ideal for engine builders upgrading from factory cast cranks or those who have experienced crankshaft failure under boost or nitrous oxide.
