Scat Forged Superlight Crankshafts
These Scat crankshafts are made from the same strong aircraft-quality forging as standard-weight cranks, but have pendulum-cut counterweights to reduce rotating mass and oil windage.

Dart GEN III Fully Counterweighted Crankshafts
Dart GEN III fully counterweighted crankshafts are built for enhanced bearing load distribution, allowing them to withstand high-boost and high-rpm applications. With eight counterweights (instead of 6), crank is substantially stiffened—which reduces flexing, and thereby puts less stress on the mains. Crank comes in a 4.000 in. stroke with an LS1 or LS7 snout, and has lightening holes in the rod journals to reduce crankshaft inertia weight for faster rotation and improved engine acceleration. Your crankshaft is the backbone of your engine—so choose one that has the quality, features, and price you want: the Dart Gen III fully counterweighted crankshaft. Additional product features: * Extra-strong, 4340 billet one-piece construction * Long and short snouts available * Heavy-duty rod cheeks * Small hole through the rod pin * Rough balanced @ 1780 grams

S&S Cycle Oil Pump Driveshaft Woodruff Keys
S&S Cycle offers oil pump driveshaft woodruff keys for a wide range of Harley-Davidson© street bikes from 1936 through 2000. The semi-circular shaped machine keys fit into a specially cut slot (called a keyway) on a shaft, preventing gears, hubs, or other components from rotating independently on that shaft. They essentially act as a locking mechanism to keep parts aligned and prevent slippage during rotation. These steel replacements are machined according to factory specs to ensure proper fitment and performance. The keys are available individually or in a set of 10.
