  • Hydraulic flat tappet design for reliable street performance
  • Aggressive lobe profile for maximum throttle response
  • Designed for modified engines with upgraded valve train components

I paid for 2nd day shipping and 5 days later they were shipped out. So, I should receive my rotors in a full week from when I paid for 2 day shipping. I called customer service and they discounted the shipping rate to ground service. At least they were polite and helpful in the phone.

great experience, good price, item arrived within 4 days of purchase, would do business with again in future !
