Manufactured in the USA from high- quality materials to help deliver maximum voltage, the wires have a high EMI/RFI suppression along with a very low resistance to help deliver the most spark possible. They feature a heavy-duty, 8.5mm-diameter silicone jacket to protect the Kevlar spiral-wound core from heat, moisture and chemicals. The wires are offered in two levels: Ultra-Spark 500 and high- performance Ultra-Spark 50. Adjustable Pushrods COMP Cams, Memphis, Tennessee, presents its patent-pending XD-A Adjustable Pushrods that incorporate a top section that slides 2 inches inside a wider bottom section, with one or two shims captured in- between.

Proven to 9,000-plus rpm in solid roller LS applications, the system provides a 90-percent increase in bending stiffness for enhanced valvetrain stability.
