Comp Cams 42030502301 Features:

• Comp Cams Xtreme Race G2 Pushrod (PN 42030502301): a 6.650 in. long, 5/16 in. diameter race pushrod built for high-lift, compromised-geometry valvetrains where stability at RPM is non-negotiable.
• Ultra-thick .106 in. wall 4130 aircraft-quality seamless Chromoly delivers up to 40% more column strength vs .080 in. walls, helping preserve valve lift by minimizing deflection under extreme spring pressure.
• Precision 210-deg tip radius improves rocker adjuster clearance to prevent binding at max lift—ideal with high-ratio rockers and aggressive cam profiles in serious competition engines.
• Centerless ground, tightly controlled runout, heat-treated/carburized to 58 RC, and finished in durable black oxide for exceptional wear and corrosion resistance across long race weekends.
• Sold as a single pushrod—choose the Xtreme Race G2 when you want maximum stiffness, accurate valvetrain motion, and confidence at the limit, lap after lap.
