NOTE - BTR does not recommend single wire conical or beehive springs with roller rockers due to the extra mass causing loss of valve train stability, or the use of a higher ratio rocker as it could possibly cause a coil bind issue. If you have a specific combination of valvetrain parts you are needing to use a roller rocker on, please call in to our sales team for clarification.
