SCAT’s forged standard weight crankshafts are designed for street or race engines with strength and reliability perfect for all LS applications. The LS series cranks are made from premium, non-twist 4340 forgings and machined to exact tolerances.
Each crank is precision ground, micro-polished, heat-treated and ion nitrided. All LS cranks come with straight shot and chamfered oil holes, have lightening holes and large radii on all journals.
SCAT LS series cranks are available in 3.622˝, 4.000˝, 4.125˝, and 4.250˝ strokes. LT1 and LS7 are also available in 4.000˝ and 4.125˝ strokes.
