Retainers & springs

[C Doo]

Has anyone had any experience with the supertech kit? Are they as reliable as the riva ones? They are half the price but concerned on quality. And also if I want to run 8650 rpm on a rxpx 260, is doing the retainers enough? Or should the springs be done also??

There are many post on the subject, and some past comparisons on spring pressure,
You want to do the springs and retainers together,
I ran the supertech in this last round of endurance racing and was hitting 8600 and above with no issues,
I smoked a new 2012 RXPX with the v-tech upgrade on the hole shot in the endurance race in round 2,
Jerry has them for a good price, you can't go wrong,

Thanks for your input. I race too and don't want anything letting go at WOT!

Does the Supertech kit include the Rocker Arm shaft bolts or do we need to order those from the GH OE Replacement store?

Thank you for your time,

I hear ya on that one... But I think there are quite a few guys running the supertech upgrade. Just trying to see if they have had any dramas with them
