Comp Cams 42030510101 Features:

• Meet Comp Cams Xtreme Race G2 Pushrod PN 42030510101—8.150 in. length, 5/16 in. diameter, .106 in. wall—built from thick-wall 4130 aircraft-quality seamless Chromoly for serious race engines.
• Delivering roughly 40% more column strength than typical .080 in. wall pushrods, it boosts valvetrain stiffness and stability to keep aggressive cams, high spring loads, and high RPM under control.
• The 210-degree radius single tip is engineered for enhanced clearance at rocker adjusters, helping prevent bind in high-lift applications or compromised geometry where standard 180-degree tips can contact.
• Precision matters: centerless-ground for consistency, held to tight runout standards, compatible with all guide plate setups, then hardened and carburized to 58 RC for durability under punishment.
• Finished in a durable black oxide coating, this is the pushrod choice when you want maximum strength, reliable clearance, and repeatable performance from the pits to the finish line.
