Thunder racing has ARP Rocker arm studs and then they have the ARP pro series rocker arm studs, whats the difference and benefits?

 

What did it say? It might have to do with the material it is made out of. Might be a stronger metal. But then again it could be the exact same metal and they could be adding the "pro".

 

from their description on Jegs: Exact length ARP rocker arm studs are straight and true to provide positive seating. 170,000 psi tensile strength (High Performance),190,000 psi (Pro-series). Not to be used with OEM-style self-locking nuts.


so the pro series are a little stronger, by about 20,000 lbs on tensile strength.

 

Well im building a 383 with a 250/300 shot...Im using the pro mag 1.6's they have those poly locks or whatever you call them. So which would yall recommend running? Heres the link to them.

I don't know what difference in price Thunder has them for but for me the $10 price difference, there is a lot to be gained for that amount of money. The stud setup is already a weak link, a ARP Pro Series 7/16 stud just makes sense and I always recomend that over going another weaker route.

I have brand new 3/8 pro mags so I will have to get the 3/8 stud because I dont want to sell my promags and loose money on those since they are brand new. But you recommend running the 3/8 pro series? Theres nothing specials needed to run those?
