dont waste your money they are known to break and destroy your motor. get S&S 605 springs or woods

I'll second that !! They are prone to breaking. This one has 43000. Got a buddy that didn't make 10,000

A buddy just broke a spring and dumped a valve in his 2018 stage 4 RG special. Fortunately the dealer appears to be willing to cover it.

I just got off the Phone not an hour ago discussing the Springs in the Stage IV M-8 Builds - They're snapping at an alarming rate. MoCo will only allow the Tech to replace the failed Spring - He's doing all 8 at his Dealership when they see it.

They have updated the springs, I think the new ones have a yellow paint marking on them. Are they any better than the old ones? We will see!
