Performance Engine Rods

Engine Rods connect the reciprocal motion of the pistons to the rotational motion of the crank. Performance engine rods, which are lighter than OE, allow for faster throttle response and acceleration. More importantly they can withstand the tension from a performance engine. Depending on what purpose your building your 2009 GMC Yukon for, the type of rod need can vary. Sport Compact Warehouse is your premier source for Performance Rods. We have a large inventory of forged rods, billet steel rods, and aluminum rods. You will also find your I-Beam, H-Beam, A-Beam, floating or press-fit rods in our inventory. If you have any questions out to one of our experienced representatives today who can help you make a more informative decision.

The valvetrain is the mechanical connection between the camshaft and intake and exhaust valves. It transforms the profiles of the rotating cam lobes into the opening and closing motion of the valves. Overhead Valve (OHV) engines have the most complex valvetrains with lifters, pushrods, and rocker arms between the cam and valves, while Overhead Camshaft (OHC) engines are much simpler, with some designs having only bucket lifters between the cam and valves.

Performance valvetrain components must be much stronger to function at high RPMs and overcome stiff valve spring pressure to open larger valves. Higher valve spring pressure is needed to prevent valve float at high RPM. Performance rocker arms and valve spring retainers are made of lighter materials to enable the engine to rev easier and achieve higher RPM, and components like roller lifters and roller rockers reduce power-robbing friction.

The OEMs switched to roller lifters long ago because roller operation made camshafts and lifters much more reliable than their flat-tappet predecessors. But reduced friction and improved durability are not the only benefits. Roller cams have much more aggressive ramp rates that would cause a flat tappet lifter to dig into the ramp.These ramp rates allow the valves to open faster and remain at high lift for most of the opening duration, which increases power. Roller cams are also much more tolerant of high valve spring pressure. Roller cam and lifter kits are available to convert older flat tappet engines.
