While engineered to be lighter on the wallet, SCAT’s LS S-Series crankshafts are heavy on benefits. Each LS S-Series crankshaft features lightening holes in all rod journals and straight-shot and chamfered oil holes for better lubrication. All throws are lightened to keep rotating mass to a minimum and all mains are gun-drilled, reducing even more mass, but also allowing for better breathing between cavities within the block. All journals are machined to a large radius at the fillet, which helps eliminate stress in this area, but also requires a bearing designed for this performance-adding feature.
SCAT’s LS S-Series crankshafts are rough-balanced to 1,800 grams and can be had in a variety of reluctor wheel selections. SCAT offers its LS S-Series crankshafts with either 24- or 58-tooth reluctor wheels or no reluctor wheel at all for either its 3.622- or 4-inch stroke versions.
