Chevy SBC 350 4340 Forged Steel Crankshaft ST4000 M350 RJ21 RMS-2Pc Bal-Int LW

Speedmaster 746-PCE276.1018 Features:

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. PCE crankshafts are nitride-hardened, with large radii on all journals for superior wear resistance, and use lightening holes in all rod throws. Scat cranks are CNC-machined for absolute tolerances and symmetry, offering ease of balance and a reduced rotating weight.

• Precision-ground, heat-treated, shot-peened, inspected, and micro-polished for superior tolerance control
• Nitride-hardened for superior wear resistance
• Features large radius on all journals for improved strength and wear resistance.
