Overview
These all new BTR Beehive springs were designed to provide maximum valve control and valve train stability in today's demanding high performance engines. Tested on both the engine dyno and Spintron to verify performance and longevity.
Spring specs:
140lb @ 1.950"
400lb @ 1.310"
Coil bind @ 1.240"
407lb spring rate
.650" max lift
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.
