Speedmaster 1-254-015 7.950" Chromoly One-Piece Pushrods 5/16" 0.080" Wall DNA

The Speedmaster 1-254-015 DNA One-Piece Pushrods deliver the strength and precision required for high-performance, high-lift cam applications. Manufactured from 4130 chromoly steel and fully heat-treated, these 7.950-inch pushrods are engineered to withstand the rigors of high-RPM operation while maintaining consistent valvetrain geometry.

Key Features:

• 7.950" overall length — uniform intake and exhaust length for straightforward installation
• 5/16" tube diameter with a robust 0.080" wall thickness for high-RPM durability
• 4130 chromoly steel construction — heat-treated for superior hardness and wear resistance
• One-piece design — no joints or welds that could fail under load
• Ball-end tips (top and bottom) with 210 degrees of rotation for maximum load-bearing surface contact
• Precision-drilled and chamfered oil holes to promote lubrication flow and prevent stress fractures
• Compatible with guideplates — heat-treated surface resists guideplate wear
• Black oxide finish for corrosion resistance

Part of Speedmaster's DNA performance series, these pushrods are an ideal upgrade for engines running aggressive camshafts, increased spring pressures, or elevated RPM targets. The tapered body design reduces reciprocating mass while maintaining structural integrity under demanding valvetrain loads.
