If you are running AFR LS3 cylinder heads on your GM LS engine, the T&D Machine Shaft Rocker Arm System is the ultimate upgrade. Designed to replace standard components with a high-performance shaft-mounted setup, this system ensures that your valvetrain remains rock-solid, even at high RPMs and under heavy load conditions.
The 1.70 ratio aluminum rockers are precision-machined to provide consistent lift and improved valvetrain geometry. By eliminating the flex associated with stock-style rockers, you can achieve better valve control, which is essential for maximizing the performance of your LS3 engine. This system is perfect for street-strip applications where reliability and performance are equally important.
