COMP Cams® Hustler™ Pushrods for GM 603/604 Crate Engines

To complement the Hustler™ Camshafts and Lifters for the GM 603/604 crate engines, COMP Cams® introduces Hustler™ Pushrods that look stock but offer superior performance in race applications with tight rules packages.

The new COMP Cams® Hustler™ Pushrods for GM 603/604 Crate Engines feature a .075” thick wall that provides a tremendous increase in stiffness over stock .060” wall pushrods, all while maintaining an OE appearance. While appearing stock, they are anything but that – they are engineered from a durable hardened tube that meets or exceeds all OE pushrod specifications and allows the use of guide plates. This high performance pushrod precisely matches the factory 7.122” length and provides less valve train deflection for improved performance.

COMP Cams® Hustler™ Pushrods are a great performance upgrade for any GM 603/604 crate engine, especially when matched with a COMP Cams® Hustler Camshaft and Lifter set.
