Step up your valvetrain stability with Dynosty LS Chromoly Pushrods, engineered for strength, precision, and durability in performance LS applications. Measuring 7.400” in length with a 5/16” diameter and .080” wall thickness, these pushrods are a serious upgrade over factory units and are highly recommended when installing an aftermarket camshaft.
Manufactured from SAE 4130 chromoly tubing, these one-piece precision formed pushrods are centerless ground to exacting tolerances and case hardened to Rc 60 for exceptional wear resistance and strength under higher spring pressures and aggressive cam profiles. Don’t risk valvetrain instability, go with quality chromoly to handle real-world performance abuse.

Frequently Asked Questions:
1. Why should I upgrade to Chromoly pushrods?
Standard OEM pushrods are prone to "deflection" or flexing when paired with aftermarket camshafts and higher-pressure valve springs. Dynosty Chromoly pushrods are manufactured from 4130 steel with a .080" wall thickness to eliminate this flex, ensuring your valve timing remains precise and your valvetrain stays stable at high RPM.
2. What is the difference between OEM-Replacement and Chromoly pushrods?
• OEM-Replacement: Best for stock or very mild street builds where factory spring pressures are maintained.
• Chromoly (This Product): Engineered with a .080" wall and case-hardened to Rc 60. These are a requirement for performance cam swaps, dual valve springs, and high-performance racing applications.
3. Will these work with my stock LS rocker arms?
Yes. These feature a 5/16" diameter and standard radius ball ends, making them a 100% "drop-in" fit for factory LS rocker arms and most aftermarket roller rockers designed for LS engines.
4. Are these compatible with 5.3L and 6.0L LS Truck engines?
Yes. 7.400" is the industry-standard length for the Gen 3 and Gen 4 LS family (1999–2013), including the 4.8L, 5.3L, and 6.0L Silverado and Sierra engines. They are the go-to choice for popular cam swaps.
5. Do I need to measure my pushrod length before buying?
While 7.400" is the standard length for most LS cam swaps with stock-height blocks and heads, we always recommend using a pushrod length checker if you have milled your cylinder heads, changed to a thinner head gasket, or are using aftermarket lifters. This ensures your lifter preload is set perfectly for maximum longevity.
