Pontiac 400 455 4340 Forged Steel Crankshaft ST-4.25 M-3.25 RJ-2.200 RMS-2Pc Ext
Overview
These PCE crankshafts are made from the same strong aircraft-quality forging as standard-weight cranks, but have profiled counterweights for less weight. PCE lightweight crankshafts are perfect for engines wanting quicker rpm. These crankshafts feature profiled aero-wing counterweights and have straight shot and chamfered oil holes. PCE crankshafts are nitride-hardened, with large radii on all journals for superior wear resistance, and use lightening holes in all rod throws.
