The function of the Chevrolet Suburban Pushrod directs the camshaft motion to the valves so that the big SUV can breathe and develop torque reliably. The Pushrod operates inside an overhead valve configuration, riding a lifter on a cam that seats atop the block, moving up and tipping a rocker arm that opens or closes each valve, dropping as the lobe swings away. The simple Pushrod keeps the cam low so the engine can be compact yet still produce sturdy low-end power. Throughout the decades, the Suburban has kept the traditional OHV pattern, so the Pushrod system doesn't change much, though better metals and oiling have helped longevity. Every version of the model utilizes steel tubular Pushrods sized for each generation's valve lift. The earlier thin wall Pushrod has since been replaced by thicker wall versions. These latter pieces do not bend when subjected to stresses caused by high heat, high rpm, or weak valve springs. In cases where clearance enlarges due to wear between cam lobes, lifters, and rocker arms, the rod may flex or bend. This can result in ticking, misfiring, and power loss. Regular oil changes and the right spring pressures keep Chevrolet engines happy and prevent Suburban valvetrain damage. Chevrolet prefers this mechanical linkage for its simplicity and durability, despite new electronics and fuel systems.
