CoreStrike value proposition
Patent-pending CoreStrike technology reinforces the elastomer element tooth geometry and shear plane. Operating temperature range -40 F to 200 F per manufacturer documentation.
Dodge accelerated dynamic lifetime head-to-head testing under 150% torque, 1 degree angular misalignment and up to 0.08 in parallel misalignment. 2.5x longer life than nearest industry competitor per manufacturer documentation. Laboratory qualification; not an unconditional real-world lifetime guarantee.
