First introduced back in 1987, the Crower Sportsman rod was the original high performance stock replacement rod. Features traditional thru-bolt and nut fasteners for stock legal classes. All Sportsman aircraft quality rods are forged from two separate dies each dedicated to a specific length (5.7"/6.0"). This forms a more uniform molecular grain flow for a stronger, more reliable rod than other brands using one die for several lengths, then cutting to size. Includes 3/8 8740 bolts and nuts (180,000 psi).
