Product Description
Michigan Motorsports 7.550" Chromoly 5/16" Pushrods
High-Strength One-Piece Chromoly Pushrods | 7.550" Length | 5/16" Diameter | .080" Wall Thickness
Upgrade your valvetrain with Michigan Motorsports 7.550" Chromoly 5/16" Pushrods. These high-strength one-piece pushrods are designed for engine combinations that require a verified 7.550" pushrod length and added valvetrain stability. Built from SAE 4130 chromoly tubing, each pushrod is precision formed, centerless ground to exacting tolerances, and case hardened to Rc 60 for excellent strength, wear resistance, and long-term durability. With a 5/16" diameter and .080" wall thickness, these pushrods are a strong choice for LS camshaft swaps, cylinder head changes, lifter changes, valvetrain geometry correction, and performance engine builds where factory-style pushrods may not provide the required length or strength.
Key Features & Benefits
- 7.550" Pushrod Length: Designed for engine combinations requiring a verified 7.550" pushrod length. This size is commonly used when valvetrain geometry changes from factory specifications due to camshaft upgrades, cylinder head work, block machining, lifter selection, or custom engine assembly.
- SAE 4130 Chromoly Construction: Built from one-piece SAE 4130 chromoly tubing for superior strength compared to standard factory-style pushrods. Chromoly construction helps support improved durability in performance applications with upgraded valve springs, larger camshafts, and increased RPM demands.
- 5/16" Diameter with .080" Wall Thickness: The 5/16" diameter and .080" wall thickness provide a strong balance of stiffness, clearance, and durability for many performance valvetrain setups. Added pushrod stiffness helps reduce flex and supports more accurate valve motion at higher engine speeds.
- Precision Ground for Consistency: These pushrods are centerless ground to exacting tolerances to help maintain consistent length, fitment, and valvetrain operation across the complete set. Precision manufacturing is critical for proper preload, rocker geometry, and dependable engine performance.
- Case Hardened to Rc 60: Case hardening to Rc 60 creates a durable wear surface for long service life in demanding valvetrain environments. This makes these pushrods a strong upgrade for street performance builds, race engines, camshaft installs, and custom LS engine combinations requiring added strength.
