G3 rocker arms

So Jesel just cam out with a rocker set up that uses the stock rocker pads like the TD.
Intakes ratio is 1.80 Ex is 1.85
Comes with shafts.
These are for the Dragpak cars?
Now before you read any further grab a seat.........

They are 250.00 a rocker

Part # are as follows
EX = IRA-127210EA185
INT = IRA-127210IA180
This is the info given to me over the phone.

The ratio change is interesting. I assume these are adjustable roller tip? Roller bearing or bushed?

Price US $ ?

Manton pushrods is just coming out with a nice set too. It's on their FB, about a grand cheaper but still spendy.

Speaking of Rockers, Steff Do you still have these printed ones?

That what a new rocker cost me from Jesel when I broke one on my R5.

Apparently the Jesel rockers don't fit under many of the aftermarket valve covers. Josh King spent a [censored] load trying to find valve covers that fit. I don't know what he ended up doing in the end.

Yes, I have a huge bag of them. I'll show them to my grandkids some day.....Never made it too steel after 2 failed machining sources and 18 months. Thats why it cracks me up when people complain about cost of Gen 3 Rockers. They are not easy to machine. Many cnc set ups. Time consuming. Thats why they cost so much.

Investment casting would probably be the most economical way to make them I would imagine

This. I also spoke to a gentleman from Diversified Creations (the people who bought out Arrington) and they are reworking the rockers that Arrington offered and hope to have them out by the end of the year.

Arrington's Rockers were non adjustable. Not sure on the investment castings versus machining from billet, from a strength perspective.

I believe Norris stainless steel rockers were investment cast.

That's also known as "lost wax casting".\

Strength depends on the material. If one is comparing cast iron to forged steel the answer is obvious. However, if one is comparing a forging or billet piece of say 17-4 ph to an investment casting of the same material it would surprise you how close the strengths are.

One reason investment casting is mentioned at all is that it provides a near net shape with little machining required. Thus the investment cast rocker might cost quite a bit less.

Manton is on FB today saying that they’re shipping their rockers now. Not in the catalog yet, you have to call. $3500 and are good to .850” of lift apparently

My gen2 StageV rockers were only $1600...and those are stainless...

That’s great, but your blocks are 6K+ and heads 3K+ (Minimum). Lots of guys run the stock Gen III stuff to 7500 rpm
