Dual spring 1.300 inch Diameter

I have gone with these springs on new setup they have arrived this week.Motor should be in and running in three weeks.I went with the Comp R lifters for these springs mainly due to rpm I want to run and the spring pressure on these is higher than what 99% of what everybody is using for springs at the moment.

Thanks for the Info. So are these ok with stock lifters?

I think you need to ask the manufacturer of the springs they are pretty new on the market, more the question who here is running a similiar pressure spring withthis lift with standard lifters.

Personally the cost of these springs is nearly double compared to other duals on offer why compromise for an extra couple of hundred dollars if you are looking at a budget setup you would be better of with 987 with stock lifters.

They will work fine with the stock lifters.
